Mode 1 gives you a standard PITI breakdown \u2014 how much the property actually costs to carry each month.<\/p>\n<p>Mode 2 adds rental income offset, showing Net Monthly Cash Flow (or Net Monthly Cost if the deal is negative), plus DSCR and Break-Even Rent. Mode 3 lets you compare two or three loan scenarios side by side \u2014 say, a 30-year Conventional against a DSCR loan against a 15-year term \u2014 and highlights the lowest-cost option. Each mode defaults to investor-appropriate rates (7.5% Conventional, 8.25% DSCR, 12% Hard Money), loan type variety that primary residence calculators don&#8217;t offer, and a two-tier analysis that separates lender risk from investor outcome.<\/p>\n<p>This investment property mortgage calculator fits into a broader workflow. Start here to price the financing, then validate Year 1 operating cash flow in the <a href=\"\/rental-property-calculator\">Rental Property Calculator<\/a>, project 10-year wealth in the <a href=\"\/rental-property-roi-calculator\">Rental Property ROI Calculator<\/a>, or check lender underwriting thresholds in the <a href=\"\/dscr-calculator\">DSCR Calculator<\/a>. If you&#8217;re comparing strategies \u2014 flip vs BRRRR vs rental hold \u2014 <a href=\"\/compare-real-estate-deals\">Compare Real Estate Deals<\/a> brings everything together. The mortgage calculator handles the financing question; sibling tools handle the operating and strategic questions.<\/p>\n<p>This calculator is designed for investment properties, not primary residences. It uses 2026 investor mortgage rates (typically 7.5% Conventional, 8.25% DSCR) and investor down payment defaults (25%). This investment property mortgage calculator is not for primary residence analysis, use a primary residence mortgage calculator. All investment property mortgage calculator outputs are projections based on your inputs \u2014 not rate quotes, lender commitments, or guarantees of outcome. Enter property price and loan terms into the investment property mortgage calculator above to see projected PITI, cash flow, and DSCR instantly.<\/p>\n<div style=\"background:#f8fafc;border:1px solid #e2e8f0;border-radius:12px;padding:20px 24px;margin:1.5em 0\">\n<p style=\"font-weight:700;color:#1e3a5f;margin-bottom:12px;font-size:0.9em;text-transform:uppercase;letter-spacing:0.5px\">On This Page<\/p>\n<ul style=\"columns:2;column-gap:24px;list-style:none;padding:0;margin:0\">\n<li style=\"margin-bottom:6px\"><a href=\"#how-to-use\" style=\"color:#1e3a5f;text-decoration:none\">How to Use<\/a><\/li>\n<li style=\"margin-bottom:6px\"><a href=\"#inputs-outputs\" style=\"color:#1e3a5f;text-decoration:none\">Inputs &#038; Outputs<\/a><\/li>\n<li style=\"margin-bottom:6px\"><a href=\"#how-it-works\" style=\"color:#1e3a5f;text-decoration:none\">Formula &#038; Example<\/a><\/li>\n<li style=\"margin-bottom:6px\"><a href=\"#what-is-investment-mortgage\" style=\"color:#1e3a5f;text-decoration:none\">What Is It?<\/a><\/li>\n<li style=\"margin-bottom:6px\"><a href=\"#interpreting-results\" style=\"color:#1e3a5f;text-decoration:none\">Result Meaning<\/a><\/li>\n<li style=\"margin-bottom:6px\"><a href=\"#benchmarks\" style=\"color:#1e3a5f;text-decoration:none\">2026 Benchmarks<\/a><\/li>\n<li style=\"margin-bottom:6px\"><a href=\"#investor-types\" style=\"color:#1e3a5f;text-decoration:none\">By Investor Type<\/a><\/li>\n<li style=\"margin-bottom:6px\"><a href=\"#use-cases\" style=\"color:#1e3a5f;text-decoration:none\">Use Cases<\/a><\/li>\n<li style=\"margin-bottom:6px\"><a href=\"#limitations\" style=\"color:#1e3a5f;text-decoration:none\">Limitations<\/a><\/li>\n<li style=\"margin-bottom:6px\"><a href=\"#faq\" style=\"color:#1e3a5f;text-decoration:none\">FAQ<\/a><\/li>\n<\/ul>\n<\/div>\n<figure class=\"wp-block-image size-large\"><img decoding=\"async\" src=\"https:\/\/arvcalc.com\/blog\/wp-content\/uploads\/2026\/05\/investment-mortgage-calculator-hero-overview-1.jpg\" alt=\"Investment property mortgage calculator showing three modes and PITI input fields\" style=\"width:100%;height:auto;border-radius:8px;\"\/><figcaption>The Investment Property Mortgage Calculator offers three analysis modes: Standard PITI, Investor with Rental Offset, and Compare Loans<\/figcaption><\/figure>\n<h2 id=\"how-to-use\">How to Use the Investment Property Mortgage Calculator<\/h2>\n<p><em>From property price to projected PITI and cash flow<\/em><\/p>\n<h3>Step 1: Enter property price and down payment<\/h3>\n<p>First, start with the purchase price \u2014 what you&#8217;re actually paying, not the Zestimate or the ARV. <strong>Down payment<\/strong> defaults to 25%, which is the investor standard for most conventional investment property loans. Drop below 20% and PMI kicks in on Conventional loans, adding $100-$250\/month to your carry cost. For DSCR loans, most lenders require 25% minimum regardless.<\/p>\n<h3>Step 2: Select loan type and interest rate<\/h3>\n<p>The <strong>Loan Type<\/strong> selector is where this calculator earns its name. Five options: Conventional (most common, personal income required), DSCR (qualifies on property income, no W-2 needed), Portfolio (relationship lenders, flexible terms), Hard Money (short-term bridge at 12%+), and Second Home (semi-owner-occupied, slightly lower rate). Rates auto-adjust by type \u2014 7.5% for Conventional, 8.25% for DSCR, 12% for Hard Money in 2026. Override with your actual lender quote for precision. This calculator is designed for investment properties, not primary residences \u2014 consumer owner-occupant rates are typically 0.75-1.5 percentage points lower.<\/p>\n<h3>Step 3: Add property taxes, insurance, and HOA<\/h3>\n<p><strong>Property tax<\/strong> defaults to 1.2% of price (the US average), but this varies wildly. Texas and New Jersey run 2-3%, while Hawaii and Colorado sit under 0.7%. Toggle between entering a dollar amount or a percentage \u2014 whichever you know. <strong>Insurance<\/strong> defaults to $1,800\/year, reflecting investor rates that run higher than owner-occupant policies. <strong>HOA<\/strong> is optional. Together with P&#038;I, these form your PITI \u2014 the full monthly payment that actually hits your account.<\/p>\n<h3>Step 4: Switch to Investor Mode (Mode 2) for cash flow analysis<\/h3>\n<p>Then, click the <strong>Investor with Rental Offset<\/strong> tab and enter your Expected Monthly Rent. Pull this from comparable leases within a mile, not Zillow estimates (which tend to run 5-15% optimistic). Vacancy defaults to 8% and Operating Expenses to 30% of gross rent \u2014 covering property management, repairs, capex reserves, and turnover costs. The calculator computes <strong>Effective Monthly Rent<\/strong> and subtracts PITI to show your <strong>Net Monthly Cash Flow<\/strong>. When the number is negative, it displays as &#8220;Net Monthly Cost&#8221; \u2014 how much you&#8217;re subsidizing the property each month out of pocket.<\/p>\n<h3>Step 5: Interpret PITI, Cash Flow, DSCR, and Break-Even Rent<\/h3>\n<p>As a result, your primary output in the investment property mortgage calculator Mode 2 is <strong>Net Monthly Cash Flow<\/strong> (or Net Monthly Cost). The status badge rates the deal: green for positive cash flow, blue for break-even, amber for slightly negative, red for significantly negative. Below that, <strong>DSCR<\/strong> shows whether a lender would fund the deal \u2014 1.2 or higher is the typical threshold. <strong>Break-Even Rent<\/strong> (Gross Required Rent) tells you the minimum gross rent needed before vacancy and expenses to cover PITI.<\/p>\n<p>And here&#8217;s what trips up most investors: projected profit is an estimate based on your assumptions. A property can have negative cash flow AND still meet lender DSCR requirements. DSCR evaluates lender risk using P&#038;I only; Cash Flow evaluates your pocket using full PITI. Before committing capital, validate rental income with lease comparables and financing terms with your lender.<\/p>\n<h3>Pro Tips<\/h3>\n<p><strong>Rate reality check.<\/strong> Investor rates run 0.75-1.5 percentage points above primary residence rates. If a lender quotes you a primary residence rate for an investment property, that&#8217;s a red flag \u2014 they may be underwriting incorrectly. Use 7.5% Conventional and 8.25% DSCR as your 2026 baseline.<\/p>\n<p><strong>Break-Even Rent is higher than you think.<\/strong> It&#8217;s almost always 30-40% above your PITI. A property with PITI of $2,023 needs gross rent of roughly $3,141 for zero cash flow at standard 8% vacancy and 30% operating expenses. Many first-time investors skip this math and discover the gap after closing.<\/p>\n<p><strong>DSCR and Cash Flow aren&#8217;t the same thing.<\/strong> A DSCR of 1.25 means the lender sees enough P&#038;I coverage to fund the loan. But if property taxes and insurance push total PITI above effective rent, your monthly Cash Flow can still be negative. Always check both metrics \u2014 DSCR for approvability, Cash Flow for your bank account.<\/p>\n<p><strong>Compare before committing.<\/strong> Mode 3 puts two or three loan options side by side. A 15-year term has brutal monthly payments but slashes total interest in half. A DSCR loan has a higher rate but no income documentation. Ultimately, the right loan depends on your cash flow needs and long-term strategy \u2014 not the lowest monthly payment alone.<\/p>\n<h3>Choosing the Right Mode<\/h3>\n<p><strong>Mode 1 \u2014 Standard Amortization (blue).<\/strong> Use when you want a classic PITI breakdown showing all four components. Best for understanding the raw carry cost before rental income enters the picture.<\/p>\n<p><strong>Mode 2 \u2014 Investor with Rental Offset (indigo).<\/strong> Use when you want to see whether rental income covers the mortgage. Shows Net Cash Flow, DSCR, Cash-on-Cash %, and Break-Even Rent. This mode is unique to investor tools \u2014 primary residence calculators don&#8217;t offer it.<\/p>\n<p><strong>Mode 3 \u2014 Compare Loan Scenarios (emerald).<\/strong> Use when you&#8217;re weighing two or three different loan options. Side-by-side comparison with the &#8220;Lowest Cost&#8221; winner highlighted.

Rent-to-price ratio drives the outcome more than rate alone.<\/p>\n<h2 id=\"what-is-investment-mortgage\">What Is an Investment Property Mortgage?<\/h2>\n<p><em>How investor financing differs from primary residence mortgages<\/em><\/p>\n<p>An <strong>investment property mortgage<\/strong> finances a property you don&#8217;t live in \u2014 a rental, a flip, a short-term vacation unit. The mechanics look similar to a primary residence loan, but the terms are materially different. Rates run 0.75-1.5 percentage points higher (lenders price in higher default risk during downturns). Down payments start at 20-25%, not 3-5%. Underwriting scrutinizes the property&#8217;s rental income or demands larger cash reserves. And interest is deductible against rental income (per <a href=\"https:\/\/www.irs.gov\/publications\/p527\" target=\"_blank\" rel=\"noopener\">IRS Publication 527<\/a>) without the SALT cap that limits primary residence deductions. This calculator models the investor-specific cost structure from the start.<\/p>\n<p>Two metrics matter more than any other for investor mortgages: <strong>DSCR<\/strong> and <strong>Cash Flow<\/strong>. DSCR \u2014 Debt Service Coverage Ratio \u2014 is the lender&#8217;s question: &#8220;Does the property&#8217;s net operating income cover the principal and interest?&#8221; It uses P&#038;I only, excluding taxes and insurance from the denominator. Cash Flow is the investor&#8217;s question: &#8220;Does the deal put money in my pocket each month after everything?&#8221; It uses full PITI subtracted from effective rent.<\/p>\n<p>The critical insight: a property can meet DSCR requirements (lender approves the loan) and still produce negative Cash Flow (you write a check every month). Consequently, this happens commonly in high-tax states like Texas, Illinois, and New Jersey, where property taxes push PITI well above P&#038;I. Both metrics must be considered \u2014 one for financeability, the other for outcome.<\/p>\n<p>The 2026 rate environment makes this distinction sharper. Investor rates averaging 7.5% Conventional and 8.25% DSCR sit 250-300 basis points above pre-2022 levels. Properties that cash-flowed comfortably at 5% rates now bleed money at 7.5%. The <strong>Break-Even Rent<\/strong> required has climbed 20-30% in many markets. DSCR loan programs have surged in popularity \u2014 they don&#8217;t require personal income documentation, which appeals to multi-property investors and the self-employed. Hard money at 12-14% remains viable only for short-term flips, never long-term holds. This calculator uses 2026 defaults so your projections reflect today&#8217;s market, not a distant memory of 3% rates.<\/p>\n<h2 id=\"interpreting-results\">What Your PITI, Cash Flow, and DSCR Mean<\/h2>\n<p><em>Interpreting the primary and secondary metrics<\/em><\/p>\n<p>Your PITI is the full monthly payment \u2014 not just interest, not just principal and interest, but the complete cost of carrying this property. Cash Flow in Mode 2 shows what happens after rental income enters the picture. DSCR tells you whether a lender would touch the deal. All three together tell the financing story.<\/p>\n<h3>PITI \u2014 The Full Monthly Payment<\/h3>\n<ul>\n<li><strong>Principal (P):<\/strong> The portion reducing your loan balance \u2014 builds equity over time<\/li>\n<li><strong>Interest (I):<\/strong> What the lender charges for lending \u2014 largest component in early years<\/li>\n<li><strong>Taxes (T):<\/strong> Annual property taxes divided by 12<\/li>\n<li><strong>Insurance (I):<\/strong> Homeowner insurance divided by 12<\/li>\n<li><strong>PMI<\/strong> (if applicable): Only on Conventional\/Second Home with less than 20% down<\/li>\n<li><strong>HOA<\/strong> (if applicable): Condo or PUD association fees<\/li>\n<\/ul>\n<p>However, many primary residence calculators show only P&#038;I, which understates actual monthly cost by 20-40%. That gap has caught more than a few new investors off guard at their first closing.<\/p>\n<h3>Net Monthly Cash Flow Tiers (Mode 2)<\/h3>\n<ul>\n<li><strong>Cash Flow > $200\/mo (GREEN):<\/strong> Property pays you every month after all costs. Sustainable hold.<\/li>\n<li><strong>Cash Flow $0 to $200\/mo (BLUE):<\/strong> Self-sustaining but thin. One vacancy month can tip it negative for the quarter.<\/li>\n<li><strong>Cash Flow \u2212$200 to $0\/mo (AMBER):<\/strong> Modest monthly subsidy. May be acceptable if you&#8217;re buying for appreciation or equity build.<\/li>\n<li><strong>Cash Flow < \u2212$200\/mo (RED):<\/strong> Significant monthly cost. Verify your rent assumptions and consider alternative financing or a lower purchase price.<\/li>\n<\/ul>\n<h3>DSCR Tiers (Lender Underwriting)<\/h3>\n<ul>\n<li><strong>DSCR \u2265 1.25:<\/strong> Conventional lender-friendly range<\/li>\n<li><strong>DSCR 1.15-1.25:<\/strong> Most DSCR and Portfolio loan programs will approve<\/li>\n<li><strong>DSCR 1.00-1.15:<\/strong> Marginal \u2014 may require higher down payment or reserves<\/li>\n<li><strong>DSCR < 1.00:<\/strong> Below typical thresholds \u2014 rental income doesn&#8217;t cover P&#038;I<\/li>\n<\/ul>\n<h3>DSCR vs Cash Flow \u2014 Both Matter<\/h3>\n<p>Here&#8217;s where most investors get tripped up. <strong>DSCR<\/strong> uses only P&#038;I as debt service \u2014 it&#8217;s a lender underwriting metric that answers &#8220;Will the property income cover the mortgage payment?&#8221; <strong>Cash Flow<\/strong> uses full PITI \u2014 taxes, insurance, HOA, everything \u2014 subtracted from effective rent to answer &#8220;Will this deal actually put money in my pocket?&#8221;<\/p>\n<p>A property in Houston with DSCR of 1.25 and Cash Flow of \u2212$150\/month is simultaneously lender-approvable and investor-negative. The lender sees enough P&#038;I coverage. You see a $150\/month drain. Both are correct. Both must be weighed.<\/p>\n<h3>Break-Even Rent (Gross Required Rent) \u2014 What It Tells You<\/h3>\n<p>This is the minimum gross rent \u2014 before vacancy and expenses eat into it \u2014 needed to cover your full PITI. It&#8217;s always higher than PITI, typically by 30-40% at standard 8% vacancy and 30% OpEx assumptions. When your market rent sits below this number, the deal will be cash-flow negative under these assumptions. A PITI of $2,023 translates to a Break-Even Rent of $3,141 \u2014 55% higher.<\/p>\n<h3>2026 Investor Mortgage Market Context<\/h3>\n<p>Since 2021, rates have climbed 250-300 basis points since 2021, compressing cash flow margins across most US markets. Many Sunbelt rentals that produced $200-$400\/month positive cash flow at 5% rates now show negative cash flow at 7.5%. DSCR loans have become the fastest-growing investor product \u2014 no income docs, property-based qualification, rates roughly 1 point above conventional. Hard money holds steady at 12-14%, making sense only for 6-12 month flips. Running your deal at actual 2026 rates, not leftover assumptions from YouTube videos recorded in 2020, is the single most important thing this investment property mortgage calculator does.<\/p>\n<figure class=\"wp-block-image size-large\"><img decoding=\"async\" src=\"https:\/\/arvcalc.com\/blog\/wp-content\/uploads\/2026\/05\/investment-mortgage-calculator-results-panel-1.jpg\" alt=\"Investment mortgage calculator PITI results with payment breakdown\" style=\"width:100%;height:auto;border-radius:8px;\"\/><figcaption>Results panel shows full PITI breakdown \u2014 principal, interest, taxes, and insurance<\/figcaption><\/figure>\n<h2 id=\"benchmarks\">Investment Property Mortgage Benchmarks for 2026<\/h2>\n<p><em>Rate ranges, typical PITI, and lender thresholds<\/em><\/p>\n<p>These are illustrative patterns for investor mortgage scenarios in typical 2026 US markets.

Then switch to Mode 2 with conservative rent estimates (use actual lease comparables, not Zillow). Target DSCR \u2265 1.25 for comfortable lender approval and positive Cash Flow for a sustainable hold. Before signing anything, validate the full Year 1 picture in the <a href=\"\/rental-property-calculator\">Rental Property Calculator<\/a>.<\/p>\n<p><strong>Portfolio Builder (scaling to 5+ properties)<\/strong><\/p>\n<p><strong>DSCR loans<\/strong> become your best friend at scale \u2014 no personal income scrutiny means your 4th property doesn&#8217;t compete with your 3rd for DTI room. Use Mode 3 to compare DSCR vs Portfolio loan terms side by side. Negative cash flow compounds across properties, so focus on deals that at least break even individually. Run each deal through a Conservative scenario (vacancy +2%, rate +0.5%) to stress-test before adding it to the portfolio.<\/p>\n<p><strong>Fix-and-Flip Investor<\/strong><\/p>\n<p>Select <strong>Hard Money<\/strong> as your loan type with a 1-year term. Mode 2 is blocked for Hard Money \u2014 rental cash flow doesn&#8217;t apply to a flip. The calculator shows monthly carry cost during the rehab and sale period. For full flip deal analysis including rehab, selling costs, and profit projection, use the <a href=\"\/fix-and-flip-calculator\">Fix and Flip Calculator<\/a>.<\/p>\n<p><strong>Wholesaler<\/strong><\/p>\n<p>Instead, run the calculator from your end-buyer&#8217;s perspective. Enter the purchase price your buyer will pay (your contract price plus your assignment fee) and see whether the deal cash flows at investor rates. If DSCR falls below 1.0, buy-and-hold investors won&#8217;t bite. Use Mode 3 to demonstrate loan flexibility \u2014 showing a buyer that a DSCR loan at 8.25% still produces positive cash flow can close a deal.<\/p>\n<p><strong>Retirement Income Investor<\/strong><\/p>\n<p>Instead, higher down payment is your lever. Moving from 25% to 40% down cuts the loan amount \u2014 and PITI \u2014 substantially, often tipping negative cash flow into positive. Use Mode 2 with Conservative assumptions (higher vacancy, higher OpEx) for realistic retirement income projections. The <a href=\"\/rental-property-roi-calculator\">Rental Property ROI Calculator<\/a> extends this analysis over 10-30 years.<\/p>\n<h2 id=\"use-cases\">Common Use Cases<\/h2>\n<p><em>When this calculator is the right tool<\/em><\/p>\n<p><strong>Pre-purchase financing feasibility<\/strong><\/p>\n<p>Before making an offer, project PITI and Cash Flow at realistic 2026 investor rates.

Mode 3 shows monthly payment, total interest, and lifetime cost side by side.

Rates shift weekly with market conditions.<\/p>\n<p><strong>Rental income assumptions require validation<\/strong><\/p>\n<p>The calculator processes whatever rent number you enter. Zillow Rent Zestimates tend to overstate by 5-15%. Best source: 3-5 recent lease comparables within 1 mile, matched by bedroom count and condition. Overestimated rent inflates both Cash Flow and DSCR, masking a deal that doesn&#8217;t actually work.<\/p>\n<p><strong>PMI auto-cancellation not modeled<\/strong><\/p>\n<p>PMI typically cancels at roughly 78% LTV through normal amortization. This calculator assumes PMI continues for the full loan term, which overstates total interest slightly.

That gap is the difference between positive and negative cash flow for many deals. This calculator defaults to investor rates \u2014 keep them there unless you have an actual investor quote.<\/p>\n<p><strong>Confusing DSCR with Cash Flow<\/strong><\/p>\n<p>DSCR of 1.25 doesn&#8217;t mean the deal is profitable. It means the lender sees enough P&#038;I coverage to underwrite the loan. Your actual Cash Flow can still be negative once taxes, insurance, and HOA enter the equation. A deal in Dallas with DSCR of 1.20 and Cash Flow of \u2212$180\/month is simultaneously lender-approvable and investor-negative.<\/p>\n<p><strong>Forgetting taxes and insurance<\/strong><\/p>\n<p>To illustrate, P&#038;I on a $225,000 loan at 7.5% is $1,573\/month. Add property taxes and insurance and you&#8217;re at $2,023. That&#8217;s a 29% jump that many calculators hide behind a &#8220;P&#038;I&#8221; label. Budget around PITI from day one.<\/p>\n<p><strong>Underestimating Break-Even Rent<\/strong><\/p>\n<p><strong>Break-Even Rent<\/strong> (Gross Required Rent) is typically 30-40% higher than PITI because rent must cover vacancy, maintenance, property management, and capital reserves before it covers the mortgage. PITI of $2,023 requires gross rent of $3,141 to break even at standard assumptions. The gap surprises most first-time investors.<\/p>\n<p><strong>Using Hard Money for long-term rental analysis<\/strong><\/p>\n<p>Hard money is 12-14% (per <a href=\"https:\/\/www.biggerpockets.com\/blog\/hard-money-loans\" target=\"_blank\" rel=\"noopener\">BiggerPockets<\/a>) bridge financing for 6-18 month flips.

In 2026, Conventional investor rates average 7.5% versus 6.5-7.0% for primary residence. Because the premium reflects lender risk \u2014 investment properties have higher default rates during market downturns because owners prioritize their own home&#8217;s mortgage. This calculator is designed for investment properties, not primary residences \u2014 it uses investor rates by default. For primary residence analysis, use a primary residence mortgage calculator with owner-occupant rates. Projected outputs are estimates based on your inputs; always confirm terms with your lender.<\/p>\n<h3>What does PITI stand for?<\/h3>\n<p><strong>PITI<\/strong> stands for Principal, Interest, Taxes, and Insurance \u2014 the four components of your full monthly mortgage payment. Primary residence calculators often show only P&#038;I (principal and interest), which understates actual cost by 20-40%. Full PITI also includes PMI (if applicable) and HOA fees. Always budget around PITI, not P&#038;I.<\/p>\n<h3>When does PMI apply to investor mortgages?<\/h3>\n<p>PMI applies only when down payment is less than 20% AND loan type is Conventional or Second Home. DSCR, Portfolio, and Hard Money loans typically never carry PMI \u2014 the higher base rate already covers the risk premium. PMI typically auto-cancels at roughly 78% LTV through normal amortization, though this calculator doesn&#8217;t model that cancellation in the current version.<\/p>\n<h3>Why does DSCR show approvable but my Cash Flow is negative?<\/h3>\n<p>This is the most important insight in investor mortgage analysis. DSCR uses only P&#038;I \u2014 principal and interest \u2014 as debt service. It&#8217;s a lender metric that answers whether the property&#8217;s net operating income covers the loan payment. Cash Flow uses full PITI \u2014 adding property taxes, insurance, and HOA \u2014 subtracted from effective rent. It&#8217;s an investor metric showing whether you write a check or receive one each month. In high-tax states like Texas, Illinois, or New Jersey, or high-insurance markets like Florida, property taxes and insurance push PITI far above P&#038;I. A property can easily meet DSCR of 1.25 while producing Cash Flow of \u2212$150\/month. Both numbers are correct. They answer different questions.<\/p>\n<h3>What&#8217;s a DSCR loan?<\/h3>\n<p><strong>DSCR loans<\/strong> qualify borrowers based on the property&#8217;s rental income covering the mortgage payment \u2014 no W-2s, no personal tax returns required. Typical minimum DSCR for approval is 1.15-1.25. Rates run roughly 1 percentage point above Conventional investor rates (8.00-8.75% in 2026), but underwriting is faster and doesn&#8217;t cap the number of financed properties. They&#8217;ve become the dominant loan product for portfolio investors and the self-employed.<\/p>\n<h3>Can I use this for a flip?<\/h3>\n<p>If flipping, select Hard Money as your loan type with a 1-year term. This shows your monthly carry cost during the rehab and sale period. Mode 2 (rental offset) is intentionally blocked for Hard Money \u2014 rental cash flow analysis doesn&#8217;t apply to a property you&#8217;re renovating and selling. For full flip deal analysis including rehab costs, holding costs, selling costs, and profit projection, use the <a href=\"\/fix-and-flip-calculator\">Fix and Flip Calculator<\/a>.<\/p>\n<h3>What down payment should I expect?<\/h3>\n<p>Specifically, investor minimums by loan type: Conventional 20-25%, DSCR 20-25%, Portfolio 15-30% (varies by lender), Hard Money 10-30% plus points, Second Home 10-20%. This calculator defaults to 25%. Dropping below 20% on Conventional or Second Home triggers PMI. Most investors put 25% down to avoid PMI and access better rates.<\/p>\n<h3>How do I calculate Break-Even Rent?<\/h3>\n<p><strong>Break-Even Rent<\/strong> (Gross Required Rent) = PITI \/ [(1 \u2212 Vacancy %) \u00d7 (1 \u2212 OpEx %)]. This gives the gross rent needed before vacancy and expenses to cover your full PITI. With PITI of $2,023, 8% vacancy, and 30% OpEx, Break-Even Rent = $2,023 \/ (0.92 \u00d7 0.70) = $3,141\/month. If your market rent is below this number, the deal will be cash-flow negative at standard assumptions.<\/p>\n<h3>Does this calculator model ARM or balloon loans?<\/h3>\n<p>Not in the current version. The calculator assumes fixed-rate fully-amortizing loans for the full term. Adjustable-rate mortgages and balloon notes have payment structures that change over time \u2014 initial teaser rates reset, balloons require lump-sum payoff or refinancing. For ARM or balloon analysis, work directly with your lender to model the payment schedule.<\/p>\n<h2 id=\"related-calculators\">Related Calculators<\/h2>\n<p><em>Continue your investor analysis workflow<\/em><\/p>\n<ul>\n<li><strong><a href=\"\/rental-property-calculator\">Rental Property Calculator<\/a><\/strong> \u2014 Year 1 operating cash flow with DSCR, Cash-on-Cash, and NOI.
