How the MAO formula works
MAO = (ARV × 70%) − repairs − your assignment fee. The 70% rule exists because the end buyer — usually a flipper or landlord — needs roughly a 30% margin under the fixed-up value to cover their profit, holding costs, closing costs, and the surprises every rehab hides. Your assignment fee sits on top of the buyer's math, so it gets subtracted before you make the offer. Offer at the MAO and the deal barely works; offer below it and everyone gets paid with room to spare.
4 MAO mistakes that kill deals
- Inflating the ARV. Using list prices or the nicest comp on the block instead of honest sold comparables. Three similar sold homes, half a mile, last six months.
- Underbidding repairs. Walk the property with a contractor when you can. Add 20% contingency to your own estimate — beginners almost always come in low.
- Forgetting the fee. Your assignment fee isn't free money; it comes out of the spread. A deal that "works" before your fee is a deal that doesn't work.
- Offering the MAO as the opening bid. The MAO is your ceiling. Open lower — sellers expect negotiation, and the gap is your safety margin.
MAO questions, answered
What is the maximum allowable offer (MAO) in wholesaling?
The highest price you can pay and still leave room for the end buyer's profit and your assignment fee: (ARV × 70%) minus repairs minus your fee.
What is the 70% rule in real estate?
Pay no more than 70% of after-repair value, minus repair costs. The 30% margin covers profit, holding and closing costs, and surprises. Adjust to 65% in shaky markets or 75% for light cosmetic rehabs.
What is a typical wholesaler assignment fee?
Usually $5,000–$15,000, with $10,000 a common target. It comes out of the deal's spread, so it must fit inside the MAO math above.
Should I offer exactly the MAO?
No — it's your ceiling, not your opening bid. Start below it. If the seller won't come near your MAO, the deal doesn't work; walk away.
