Deal analysis
A flip is four numbers: purchase price, rehab cost, holding cost and resale value. Get any one of them wrong by fifteen per cent and the profit is gone. The analysis starts at the back — what the finished product genuinely sells for in that specific neighbourhood — and works forward to the price you can pay.
That resale figure has to come from closed sales of comparable finished homes within a tight radius, not from active listings and not from the best sale of last spring. Everything else in the model is built on it, so it is the number worth arguing about.
