Wholesale Real Estate MAO Formula: How to Calculate Maximum Allowable Offer in 2026
Wholesale Real Estate MAO Formula: How to Calculate Maximum Allowable Offer in 2026
If you’ve ever lost a deal because you overpaid — or walked away from a deal that was actually profitable — you were missing one thing: a reliable MAO formula.
The Maximum Allowable Offer (MAO) is the single most important number in wholesale real estate. It’s the ceiling price you can pay for a property and still make money for yourself and your cash buyer. Get it right and you close profitable deals consistently. Get it wrong and you either lose money or kill every deal before it starts.
This guide breaks down exactly how to calculate MAO, what variables to use, and how top wholesalers are using tools in 2026 to run these numbers in seconds.
What Is MAO (Maximum Allowable Offer)?
MAO stands for Maximum Allowable Offer — the highest price you can offer a motivated seller while still leaving enough room for:
- Repair costs (what the buyer needs to fix the property)
- Your wholesale fee (your profit for finding and contracting the deal)
- The cash buyer’s profit (their flip margin or rental return)
The MAO is not the price you want to pay — it’s the price you can’t go above without losing money.
The Standard MAO Formula
The classic wholesale MAO formula looks like this:
MAO = (ARV × 70%) − Repairs − Wholesale Fee
Let’s break down each component:
ARV (After Repair Value)
ARV is what the property will be worth after it’s fully renovated and sold on the retail market. This is your starting point for everything.
How to find ARV:
- Pull sold comps within 0.5 miles in the last 90 days
- Match on bed/bath count, square footage (within 15%), and property type
- Adjust for condition, lot size, and upgrades
- Average your 3-5 best comps
The 70% Rule
Cash buyers (flippers) typically need to buy at or below 70% of ARV to make their numbers work after repairs, holding costs, closing costs, and profit. This is the buffer that makes the deal attractive to buyers.
Some buyers work at 65% in slower markets, 75% in hot markets — know your buyers and adjust accordingly.
Repair Costs
This is what it will cost to bring the property to retail condition. Common categories:
- Roof, HVAC, plumbing, electrical (big-ticket items)
- Kitchen and bath updates
- Flooring, paint, landscaping
- Foundation or structural issues
As a wholesaler, you don’t need a contractor-level estimate — you need a ballpark that’s close enough to structure the deal. Many wholesalers use a per-square-foot estimate ($25–$50/sqft for light rehab, $50–$80 for heavy).
Wholesale Fee
This is your cut — the spread between what you pay the seller and what you charge the buyer. Typical wholesale fees range from $5,000 to $20,000+ depending on deal size and market.
MAO Formula Example
Let’s walk through a real example:
- ARV: $250,000 (based on sold comps)
- Repair estimate: $35,000 (kitchen, bathrooms, roof)
- Wholesale fee: $10,000
MAO = ($250,000 × 70%) − $35,000 − $10,000 MAO = $175,000 − $35,000 − $10,000 MAO = $130,000
So the most you can offer the seller is $130,000. If you can get it under contract at $125,000, your buyer pays $135,000, and you walk away with $10,000 at closing.
Adjusted MAO Formula (More Accurate)
The basic formula works, but experienced wholesalers use an adjusted version that accounts for closing costs and holding costs:
MAO = ARV − Repairs − Wholesale Fee − Buyer’s Profit − Closing Costs − Holding Costs
Using the same example:
- ARV: $250,000
- Repairs: $35,000
- Wholesale fee: $10,000
- Buyer’s desired profit: $30,000 (12% of ARV)
- Closing costs (buy + sell): $8,000
- Holding costs (4 months): $6,000
MAO = $250,000 − $35,000 − $10,000 − $30,000 − $8,000 − $6,000 = $161,000
This version gives you a more precise number and helps you show buyers exactly how their profit is protected.
Common MAO Mistakes Wholesalers Make
1. Inflating ARV
The #1 mistake. Using comps from a different neighborhood, different condition, or that are 6+ months old. Always be conservative — it’s better to underprice ARV and have room than overprice and lose your buyer.
2. Underestimating Repairs
New wholesalers routinely underestimate repair costs by 30-50%. If you’re not experienced with rehabs, walk through properties with a contractor until you develop an eye for it. When in doubt, add a 10-15% contingency.
3. Too Small a Wholesale Fee
Charging $3,000-$5,000 on a $250,000 ARV deal means you’re leaving money on the table and not getting paid for your risk. Know your market and price your fee accordingly.
4. Not Knowing Your Buyers’ Numbers
Different buyers have different criteria. A fix-and-flip investor needs different margins than a buy-and-hold landlord. Know what each buyer in your list needs and calculate MAO per buyer type.
5. Negotiating Without Running MAO First
Never make an offer without running the numbers first. Walk into every seller conversation knowing your MAO — it gives you confidence and protects your deal.
MAO by Market Type
The 70% rule is a starting point, but adjust based on your market:
| Market | Buyer Multiplier | Notes |
|---|---|---|
| Hot/competitive | 72–75% | Buyers compete harder, accept thinner margins |
| Stable/suburban | 68–70% | Standard rule applies |
| Slow/rural | 60–65% | Buyers need more cushion for longer hold times |
| High-end ($500K+ ARV) | 65–68% | More dollars at risk, buyers want bigger margins |

Advanced MAO:
MAO = ARV − Repairs − Wholesale Fee − Buyer Profit − Closing Costs − Holding Costs
Red flags — walk away if:
- You can’t find 3 solid comps within 0.5 miles
- Repair estimate exceeds 40% of ARV
- Seller won’t come within 10% of your MAO
- ARV is based on active listings (not sold comps)
Frequently Asked Questions
What’s a good wholesale fee? Most wholesalers target $8,000–$15,000 per deal. On larger deals ($300K+ ARV), $15,000–$25,000 is common. Don’t go below $5,000 — it’s not worth your time and risk.
What if the seller won’t accept my MAO? Walk away or renegotiate the repair estimate. Never stretch your MAO to save a deal — you’ll either lose your buyer or lose money.
Can I use MAO for rental properties? Yes, but replace the 70% rule with a cap rate analysis. A rental buyer cares about cash-on-cash return, not flip profit.
How accurate does my ARV need to be? Within 5-10% is acceptable. If you’re off by more than that, your entire deal structure breaks. Spend the time to get solid comps.
Summary
The MAO formula is simple, but executing it well separates profitable wholesalers from ones who struggle. Master these steps:
- Find accurate ARV from sold comps
- Get a realistic repair estimate
- Know your wholesale fee target
- Apply the 70% rule (adjusted for your market)
- Never offer above your MAO
The wholesalers closing 5-10 deals a month aren’t smarter — they’re faster and more systematic. A deal analyzer built for wholesalers puts the MAO formula on autopilot so you can analyze more leads, make more offers, and close more deals.
