A fixer-upper hits the market in Austin at $189,000 \u2014 but what’s the most you should actually offer?<\/strong> The 70 percent rule calculator real estate investors trust answers that question in about three seconds. Plug in your After-Repair Value and rehab estimate, and the tool screens your Maximum Allowable Offer using the commonly used formula: MAO = ARV \u00d7 70% \u2212 Rehab. For a property with a $250,000 ARV and $30,000 in renovation costs, that’s a screened MAO of $145,000 \u2014 leaving a 30% buffer for financing, holding costs, selling expenses, and profit.<\/p>\n

This 70 percent rule calculator real estate tool works as a first-pass screening heuristic, not a full deal analysis. As a 70 percent rule calculator real estate screening tool, think of it as the screening gate before you invest hours running detailed numbers. The tool offers three distinct modes: Standard 70% for quick screening, Adjustable Percentage (60\u201380%) for market-specific conditions, and Reverse Mode that lets wholesalers check whether their contract price fits the end-buyer’s 70% Rule. A built-in Financing Buffer toggle accounts for 2026’s high hard-money rates (12\u201314%), and two-tier status badges classify every deal from Deep Value to High Risk.<\/p>\n

The 70 percent rule calculator real estate professionals rely on sits in the middle of a three-tool workflow most flippers use. First, the ARV Calculator<\/a> establishes your After-Repair Value from comparable sales. Then this tool screens whether the deal passes at your target percentage. If it does, you run the full numbers in the Fix and Flip Calculator<\/a> to model specific financing, holding, and selling costs before making an offer. Screening saves time. Full analysis saves capital.<\/p>\n

One thing to be clear about upfront: the 70 percent rule is a screening heuristic \u2014 it embeds generalized cost assumptions that may not match your specific deal. For committed capital decisions, always validate with the Fix and Flip Calculator for precise modeling of your financing rate, holding period, and selling costs. The numbers here are projections, not guarantees.<\/p>\n
