Free ARV Calculator for Real Estate Investors — Offa ARV

ARV — After Repair Value — is the single most important number in any flip, BRRRR, or rehab project. Get it wrong by 10% and you've eaten your profit margin. Get it wrong by 20% and you're losing money before you've poured a foundation. Offa ARV pulls real local comps, runs the math, and gives you an accurate after-repair value in seconds. Free to try, no signup needed.

How ARV Works

ARV is what your property will sell for after you finish renovating it. It's the foundation of the 70% rule (max purchase price = ARV × 0.70 − rehab costs) and every reliable underwriting method. Getting an accurate ARV means pulling comparable sales — properties similar to yours, in the same neighborhood, sold recently in renovated condition.

Doing this manually is painful: pulling MLS comps, filtering by condition, adjusting for square footage and beds. Our tool does it in seconds.

How to Use Offa ARV

1. Go to arv.offa.com.
2. Enter the property address.
3. Add basic details (beds, baths, square footage).
4. Get instant ARV with the comps that backed up the number.

You see exactly which sales we pulled and how we weighted them — no black box, no AI hallucinations.

When to Trust an ARV Estimate

Any ARV tool — ours included — is only as good as the local comp data. Trust it more in active markets with lots of recent sales. Trust it less in rural areas, unique properties, or markets where you couldn't find 3+ true comps. When in doubt, run a manual sanity check.
