Maximum Allowable Offer (MAO)
The Maximum Allowable Offer (MAO) is the absolute ceiling purchase price a real estate investor or wholesaler can offer on a distressed property to ensure holding costs, repair budgets, and desired profit margins are fully protected.
Updated with grounded research as of 2026-07-22.
The short answer
A Maximum Allowable Offer (MAO) is the strict upper financial boundary that real estate flippers and wholesalers set when acquiring off-market or distressed properties. Calculating MAO prevents investors from overpaying by factoring in the projected After Repair Value (ARV), total renovation expenses, holding costs, closing fees, and target profit margins.
Key facts
- Traditional 70% Rule Formula
- MAO = (After Repair Value × 0.70) - Estimated Repair Costs
- Wholesaler MAO Formula
- MAO = (After Repair Value × 0.70) - Repair Costs - Wholesaler Assignment Fee
- Fixed-Cost Detailed Formula
- MAO = ARV - Repair Costs - Holding Costs - Closing/Selling Costs - Target Profit
Understanding the Standard MAO Formulas
Real estate investors typically employ two main approaches to determine their Maximum Allowable Offer: the standard 70% Rule shortcut and the comprehensive Fixed-Cost Method. The 70% Rule assumes that all overhead—such as loan interest, property taxes, insurance, and closing costs—fits within a 30% margin buffer alongside the investor's profit.
- The 70% House Flipping Rule: MAO = (ARV × 0.70) - Estimated Repairs.
- The Wholesaling Rule: MAO = (ARV × 0.70) - Estimated Repairs - Assignment Fee.
- Fixed-Cost Method: MAO = ARV - Estimated Repairs - Financing/Holding Costs - Selling Expenses - Required Profit.
Local Factors Impacting MAO Calculations in Idaho
In moderate-margin or highly competitive submarkets, investors frequently adapt the traditional 70% rule to 75% or 80% to remain competitive. However, changing local dynamics require disciplined underwriting rather than loose assumptions.
- Treasure Valley Pricing Context: As of December 2025, Ada County's median home price stood at $525,000 (with an average 36 days on market), while Canyon County's median home price reached $435,000 (with 49 days on market). Higher median entry prices mean misjudging repair budgets or holding timelines can severely cut into target profit margins.
- Regulatory Changes in 2026: The Idaho Legislature passed six significant housing supply bills in early 2026—covering accessory dwelling units (ADUs), lot splitting, and streamlined permitting. Investors establishing ARVs must account for increased local housing inventory and potential starter-home competition across Idaho municipalities.
Key Limitations and Risk Protection Strategies
Relying solely on a rule of thumb can expose flippers and wholesalers to substantial financial risk if market conditions shift or unexpected property issues arise during construction.
- Accurate Comps: The accuracy of MAO relies entirely on establishing a realistic After Repair Value using comparable recent sales in the immediate neighborhood.
- Contingency Planning: Construction labor and materials fluctuate; experienced flippers add a 10% to 20% contingency line item directly into their estimated repair budget before running the final MAO calculation.
- Carrying Cost Reality: Higher mortgage rates mean holding costs (hard money loan interest, utility costs, property taxes) compound quickly if days on market extend beyond projected schedules.
Common questions
What is the difference between an MAO for a flipper and an MAO for a wholesaler?
A house flipper's MAO calculates the direct purchase ceiling required to hit their own profit target after completing renovations. A wholesaler's MAO must subtract an additional wholesale assignment fee (e.g., $10,000–$20,000) so that the contract remains profitable when assigned to the end cash buyer.
Why do some investors use an 75% or 80% multiplier instead of 70%?
In higher-priced markets or areas with rapid price appreciation, a strict 70% formula may lead to underbidding on every available opportunity. Higher percentages allow investors to submit more competitive offers, but it reduces their safety margin for unexpected rehab overruns or holding delays.
