Formula & Theory — After Repair Value Calculator

House flippers use ARV to estimate the post-rehab value of a property. The 70% rule caps the purchase plus repair cost at 70% of ARV to leave room for fees, holding costs, and profit.

ARV = w × Comps + (1 − w) × (Purchase + Repair)
Max offer = 0.70 × ARV − Repair

Frequently asked questions about After Repair Value Calculator

What is the 70% rule?

A heuristic that limits offer + rehab cost to 70% of ARV to ensure adequate profit margin after closing, holding, and selling costs.

How do I weight comps vs. cost?

In strong comparable markets weight comps higher; for unique properties with few comps, weight the cost approach.

Are agents fees included?

No. Subtract agent commission, closing fees, and holding costs separately to refine the profit estimate.

Can I use this outside the U.S.?

Yes. The math is the same; calibrate the rule (some use 65% or 75%) to match local margins.

Is my data stored?

No. All calculations run locally in your browser; nothing is sent to a server.
