Then subtract a percentage of arv you would be happy capturing after forced appreciation with the rehab and you should end up with a ballpark number of where your offer would need to be to make sense.

Here's a simple example (because I'm a visual learner lol):Assumed ARV = $115,000Purchase Price + Cost = $45,000Rehab Costs = $35,000All In Costs (total above) = $80,000 financed fully by a HMLBut then the appraisal comes back at $100,000 and you're only able to obtain an 75% LTV, meaning you'll only cash out $75,000.
