How to Calculate Maximum Allowable Offer (MAO)
Learn the exact formula to avoid overpaying and ensure every real estate deal makes you money.
In real estate investing, your profit isn't made when you sell—it's made when you buy. If you overpay for a property by even $10,000, you are effectively working for free for the first three months of your renovation.
The most successful investors don't rely on "gut feelings" or what the listing agent says is a "good deal." Instead, they use a strict mathematical threshold known as the **Maximum Allowable Offer (MAO)**.
This is your "line in the sand." It is the absolute highest price you can pay for a property while still hitting your target profit and accounting for all risks. In this guide, we will break down the MAO formula step-by-step and show you how to calculate it like a pro.

What is Maximum Allowable Offer (MAO)?
The Maximum Allowable Offer (MAO) is the ceiling price an investor is willing to pay for a distressed property. It is derived by taking the projected sales price (After Repair Value) and subtracting all costs.
"Your MAO is the highest price you can pay while still hitting your target profit. No exceptions."
The Two Primary MAO Formulas
The 70% Shorthand
Best for quick screening of deals. It assumes a 30% wedge for profit and costs.
The Fixed-Profit Model
Best for advanced investors with precise control over their overhead and margins.
How it Works: The Logical Breakdown
The MAO formula works backward from the finished product. You start with what the house will actually be worth on the open market after it’s beautiful (The ARV).
Selling Costs
Agent commissions and closing fees (usually 8-10% of ARV).
Holding Costs
Loan interest, taxes, and insurance during the renovation.
Repair Costs
Material, labor, permits, and a 10% contingency.
