Free Wholesale Deal Calculator — MAO and Assignment Fee
The wholesale deal calculator answers two questions: what can your buyer pay (MAO), and how much room is there for your assignment fee? FreeDealCalc runs both free in one conversation with Freddie.

Buyer MAO = (ARV × 0.70) − Rehab
Your assignment fee lives in the spread between the buyer's MAO and your contract price. If the buyer's MAO is $180,000 and you can get the seller to $155,000, your potential fee is up to $25,000.
What FreeDealCalc Calculates
- ARV from Rentcast comparable sales
- Buyer's max allowable offer at 65%, 70%, and 75% thresholds
- Your potential assignment fee at different contract prices
- Deal score — is this worth pursuing?

Calculate My Assignment Fee →Why the MAO Threshold Matters
Your buyer uses the 70% rule as a maximum. If you contract a property above their MAO there's no room for your fee — the deal is unsellable. Always calculate MAO before you negotiate with the seller, not after. The number tells you your ceiling, and your ceiling determines whether the deal is worth pursuing at all.
