Real Estate Investment Calculator

Model any acquisition end to end: purchase price, repair budget, closing, holding and selling costs, financing at your actual rate, and your assumed exit value. The calculator returns the gross spread, total cost stack and net position so you can see exactly where a deal makes or loses money.

  • Every number is an input you enter. Nothing is scraped, inferred or estimated on your behalf.
  • Outputs are user-modeled estimates, not appraisals, predictions or investment advice.
  • Verify assumptions with a title search, independent appraisal or BPO, a licensed inspection and a written insurance quote before committing.

How the maximum allowable offer (MAO) is calculated

Investors use the maximum allowable offer formula to cap what they can pay for a property and still hit their required return. The classic shortcut is the 70 percent rule — 70% of the after-repair value minus repairs — but it ignores financing costs, holding time, closing fees and your actual margin of safety. This calculator works the MAO the defensible way: start from your assumed exit value, subtract the full cost stack (purchase closing, repairs, holding, financing and selling costs) and your required profit, and the remainder is the most you can offer. Every figure is an input you control, so you can defend the offer line by line to a partner, a lender or a seller.
