The room between what a rehab buyer can pay (your MAO after fee) and what you have the property under contract for. Positive spread means the assignment can work at those numbers.

Why is the first offer 5% under MAO?

That is the same opening discount RehabOS uses on the wholesale worksheet. It leaves room to negotiate without starting at your ceiling.

Do I have to enter a contract price?

No. Without it you still get buyer sale price, MAO, and a first offer. Add contract price when you want to see spread.

How to use this calculator

Price the house the way a rehab buyer would: ARV minus repairs at their rule percent.
Enter your assignment fee. That comes out of the price you can pay the seller.
If you already have it under contract, enter that price to see if a spread is left.
