How to Calculate MAO in Wholesale Real Estate (The Beginner's Step-by-Step)

You found a house. Someone gave you an address, or you drove past a beat-up property, and something clicked — this could be a deal. Now you're staring at your phone trying to figure out if the numbers actually work before someone else moves on it.

That number you need is called MAO — Maximum Allowable Offer. It's the highest price you can pay for a property and still make a real wholesale deal work. Learn how to calculate MAO in wholesale real estate once, and you'll never look at a distressed property the same way again.

What Does MAO Mean in Wholesale Real Estate?

MAO stands for Maximum Allowable Offer. It's the ceiling — the absolute most you should offer a seller if you want the deal to actually close and your buyer to actually show up.

It's not a negotiating position. It's not a starting bid. It's the mathematical line between a deal that works and one that wastes three weeks of your life.

Most beginners skip the math because it feels complicated. Then they get a property under contract, market it to buyers, and get nothing but silence. The MAO formula is how you stop that from happening.

The MAO Formula Explained Simply

Here it is:

ARV × 0.70 − Estimated Repairs = MAO

Three variables. That's it.

ARV is After Repair Value — what the property would sell for fully fixed up. The 0.70 is your target factor, which we'll talk about in a second. And repairs are what it actually costs to get the property to that ARV condition.

One important thing: that 0.70 is a starting default, not a fixed law. In slower markets or thinner buyer pools, you may need 65% or lower. In strong markets with deep cash buyer demand, some investors push to 75%. The 70% default is a floor to start from, not a ceiling to aim for. Use it until you know your market well enough to adjust it.

Now let's break down each variable so you can actually use this.

How to Find ARV (And Why Getting It Wrong Kills the Deal)

ARV is the price a fully renovated version of this property would sell for, based on comparable homes that have actually sold nearby — not the Zillow estimate, not active listings, not what the seller thinks it's worth.

Active listings are just asking prices. What matters is what buyers have already paid.

To pull comps correctly, you need: sold homes (not active), within 0.5 miles, same bed and bath count, sold in the last 90 days, and within 15% of your property's square footage. If your market is thin, you can stretch to 120–180 days — but note the trend. If prices are dropping, your 6-month-old comp is too optimistic.

Get this number wrong and everything downstream breaks. A $20,000 ARV error turns into a $14,000 MAO error. That's the difference between a deal your buyer jumps on and one that sits for six weeks.

How to Estimate Repairs Without Being a Contractor

You don't need to be a contractor. You need a system.

Start with a per-square-foot heuristic based on condition. Cosmetic only — paint, flooring, light fixtures, landscaping — runs $15–28 per sqft. Moderate work, meaning kitchen or bath updates plus cosmetics, runs $35–55. Significant rehab with system replacements lands at $55–80. A full gut down to the studs is $85–130.

Then add line items for the things that blow up budgets without warning:

• HVAC replacement: $5,000–14,000.
• Roof replacement: $8,000–22,000 depending on size and material.
• Foundation piers: $1,800–3,500 each — and a full perimeter job can run $30,000–80,000.
• Electrical panel replacement: $2,800–6,500.
• And if the house has a Federal Pacific or Zinsco panel, flag it — lenders won't touch those properties, which cuts your buyer pool dramatically.

When in doubt, add a $5,000–8,000 buffer to your repair estimate. Experienced wholesalers do this automatically. Beginners skip it and wonder why buyers keep asking for price reductions.

Putting It All Together: A Real MAO Calculation

Let's run the math on a real example.

You find a 3-bed, 2-bath house in a neighborhood where renovated comparable homes are selling for $245,000. The property needs a moderate rehab — new kitchen, updated bathrooms, fresh paint and flooring throughout — on 1,400 square feet. You estimate repairs at roughly $32,000 (about $23/sqft with a buffer for a few surprises).

Here's the formula:

$245,000 ARV × 0.70 = $171,500
$171,500 − $32,000 repairs = $139,500 MAO

That $139,500 is the most you can pay and still have a deal. But that's the buyer's purchase price — what they pay you. Your offer to the seller needs to account for your assignment fee.

If your fee is $12,000:

$139,500 − $12,000 = $127,500 offer to the seller

That's the number that goes into the contract.

What Happens After You Calculate MAO?

The MAO tells you whether to move forward. If the seller's price expectation is anywhere near $127,500, you have a deal worth pursuing. If they want $185,000, the math doesn't work — walk away and use the time on the next lead.

If it does work, you get the property under contract at or below your MAO, then market the deal to your buyers list at or near the full MAO price. The spread between your offer to the seller and what you charge your buyer is your assignment fee.

That's the whole model. Wholesaling Workflow: Lead to Close.

If you're running these calculations on every lead manually, you'll burn out fast. A lot of beginners use DealFlowOS to track their deals, store their MAO calculations, and keep their pipeline organized in one place — so the math doesn't live in seventeen different notes apps. Worth knowing about when you're ready to get serious.

The formula isn't complicated. What separates wholesalers who close deals from ones who don't is doing the math every single time, on every single lead, before they get emotionally attached to a property.
