Maximum Allowable Offer (MAO): How Investors Determine the Right Price for a Deal

Maximum Allowable Offer (MAO) is the highest price an investor can pay for a property while still meeting their required profit margin. It is based on the property’s expected After Repair Value (ARV), minus repair costs and a target discount that covers profit and fees.

MAO protects investors from emotional decision-making and ensures every deal is evaluated with discipline. Whether you’re flipping houses or buying distressed rentals, MAO gives you a clear ceiling for your offer.

Here is the standard MAO formula used by real estate investors:

MAO = (ARV × Discount Rate) − Repair Costs

Where:

• ARV = After Repair Value
• Discount Rate = typically 70% for flips, but can range from 65%–80% depending on market conditions
• Repair Costs = estimated renovation expenses

Some investors also subtract holding costs, closing costs, and contingency reserves, but the core formula above is the primary industry standard.

Example Scenario

An investor is evaluating a distressed property with the following numbers:

• ARV: $300,000
• Investor Discount: 70%
• Repair Costs: $45,000

Step 1: Calculate the Discounted Value
$300,000 × 0.70 = $210,000

Step 2: Subtract Repair Costs
$210,000 − $45,000 = $165,000

Maximum Allowable Offer = $165,000

The Insight: In this scenario, the Discount Amount is $90,000 (the 30% spread). This is the buffer that must cover your profit, closing costs, and holding fees.

There is no single “good” MAO number because MAO is a result, not a metric with a target range. However, choosing the right Discount Rate is critical for a safe result:

• 65%–70% → common for heavy rehabs or uncertain markets where you need a larger safety net
• 70%–75% → typical for standard flips
• 75%–80% → used in hot markets or for light cosmetic updates

The more risk involved, the lower the percentage should be.

MAO matters because it:

• protects your profit margin
• prevents overpaying in competitive markets
• creates a disciplined, repeatable acquisition process
• helps you evaluate deals quickly
• reduces risk when flipping or rehabbing properties

Without MAO, investors often rely on emotion or guesswork — which leads to thin margins or losses.

Pros

• Simple and fast to calculate
• Helps investors avoid overpaying
• Works well for distressed and flip‑focused deals
• Creates a consistent acquisition strategy
• Easy to adjust for different risk levels by changing the Discount Rate

Cons

• Can be too conservative in hot markets
• Relies heavily on accurate ARV and repair estimates
• Not ideal for long‑term rental analysis
• May cause investors to lose deals if competitors use higher percentages

Common mistakes when calculating MAO include:

• Overestimating ARV — the most dangerous error
• Underestimating repair costs — failing to account for “hidden” issues
• Using the wrong discount percentage — being too aggressive to win a deal
• Ignoring holding and selling costs — forgetting they eat into your Discount Amount
• Failing to include a contingency buffer — leaving no room for the “unknowns” that arise in every rehab
• Letting emotions override the formula — talking yourself into a higher offer just because you “like” the property
• Ignoring realistic inputs — assuming best-case scenarios rather than using verified market data

MAO only works when the inputs are realistic.

MAO vs ARV
ARV is the property’s value after repairs.
MAO is the maximum price you can pay based on that value.

MAO vs Cash Flow
MAO is for flips and distressed deals.
Cash flow is for long‑term rentals.

MAO vs ROI
ROI measures return on investment.
MAO sets the purchase price needed to achieve that return.

MAO vs GRM or Cap Rate
GRM and Cap Rate evaluate rental performance.
MAO evaluates acquisition pricing for flips.

Market conditions should dictate the Discount Rate you plug into the formula:

• Hot markets: investors may use 75%–80% to stay competitive
• Cold markets: investors may tighten to 65%–70% to account for longer holding times
• High labor/material costs: repair estimates increase, lowering MAO
• High interest rates: holding costs rise, reducing your MAO
• Strong buyer demand: ARV may be more reliable
• Uncertain markets: investors often use more conservative numbers

Adjusting MAO for local conditions is essential.
