Maximum allowable offer (MAO) = ARV × 70% − rehab cost. Runs in your browser; nothing is saved.
Example: ARV of $250,000 × 70% = $175,000, minus $40,000 rehab = a $135,000 maximum offer. The remaining 30% of ARV ($75,000) has to cover buying and selling costs, loan interest and points, holding costs, and your profit.

It's a quick screen: your maximum purchase price should be about 70% of the after-repair value (ARV), minus the rehab cost. The 30% left is meant to cover financing, holding, selling costs, and profit.
It's a rule of thumb. In expensive or competitive markets, investors often go above 70% on cheaper rehabs; in slow markets or on heavy rehabs, many stay below it. Always run a full cost breakdown.
Not explicitly. They're assumed to fit inside the remaining 30%, along with profit. That's why a full calculator is the better final check.
