I too am having difficulty wrapping my head around this.
Assuming the standard formula OFFER = (ARV * .60) - REHAB you come out with very low numbers for an offer. Say we take a 1,500 square foot house, with an ARV of $100,000, you'd come up with an offer of $51k? Looking at the numbers i'd LOVE to buy the house at that price, but why would they love to sell it to me?
1,500 sq ft
Paint = 3,750
Flooring = 1,875
HVAC = 3,000 (or any other major system that happens to need replacing)
Total Rehab = $8,625
ARV = $100,000
x .6
= 60,000
- 8,625
= 51,375
This would leave room for $48,625 profit. Even after I take a $5-7,000 cut, the rehabber is still looking at $40,000 profit. Surely the seller could find someone to offer more. Even if they threw it on the market for $75,000, they'd find a buyer quicker than a wholesaler could find them, wouldn't they?
