Why ARV Is the Most Important Number in a Foreclosure Deal
Every offer flows from ARV
Your after repair value calculator result drives your maximum purchase price, your rehab budget, your financing, and your projected profit. Get the ARV wrong and every downstream number is wrong too — which is how investors lose money on otherwise promising foreclosures.
Comps beat guesswork
The price per square foot method anchors your valuation to what real buyers actually paid for similar, renovated homes nearby. This comps calculator averages your comparables and shows a defensible range instead of a single optimistic guess.
Distressed buyers need it fast
At auction or in pre-foreclosure you often have minutes, not days. A quick ARV calculator paired with the 70% rule gives you a confident max offer on the spot so you never overpay for a distressed property.

How to Calculate ARV the Right Way
ARV is part art, part discipline. Here's the method professional flippers and wholesalers use to value a property after renovation.
The Price-Per-Square-Foot Method
The fastest defensible way to value a renovated home.
Pull at least three recently sold, renovated homes near your subject property. For each, divide the sale price by the living area to get a price per square foot. Average those numbers, then multiply by your subject property's square footage to estimate its after repair value.
Because a single outlier comp can skew the result, this calculator also shows a low-to-high ARV range using your cheapest and most expensive comps — so you can underwrite conservatively.
The Formula
What Separates a Good Comp From a Bad One
Garbage in, garbage out — your ARV is only as good as your comps.
Strong Comps
- Within ~1 mile of the subject
- Sold in the last 3–6 months
- Within ~20% of the square footage
- Same property type and renovated finish
Weak Comps
- Different school district or neighborhood
- Sold over a year ago
- Distressed or as-is sales
- Major size, lot, or condition mismatch
ARV Calculator FAQs
Common questions about after repair value, comps, and the 70% rule.
How is ARV calculated?
The most common method is price per square foot. Take 3 or more recently sold comparable homes near your subject property, divide each sale price by its living area to get a price per square foot, average those figures, then multiply by your subject property's square footage. This calculator does all of that instantly and also shows you a low-to-high range based on your cheapest and most expensive comps.
What makes a good comparable sale (comp)?
Strong comps are within roughly one mile of the subject, sold within the last 3 to 6 months, similar in square footage (within about 20%), the same property type and style, and ideally already renovated to a similar finish level as your projected after-repair condition. The closer your comps match, the more reliable your ARV estimate.
What is the 70% rule and how does it use ARV?
The 70% rule is a fast screening formula house flippers use: your maximum offer should be no more than 70% of the ARV minus estimated rehab costs. For a property with a $400,000 ARV and $50,000 in rehab, the max allowable offer is ($400,000 × 0.70) − $50,000 = $230,000. This calculator computes it automatically and lets you adjust the percentage for your market and risk tolerance.
How accurate is an ARV calculator?
An ARV calculator gives a solid initial estimate for screening deals, but it is only as accurate as the comps you feed it. Price per square foot can vary widely by neighborhood, lot size, condition, and upgrades. Always confirm with a licensed appraiser, a real estate agent's CMA, or an in-person walkthrough before making a binding offer.
Can I use this ARV calculator for wholesale deals?
Yes. Enter your assignment fee in the wholesale field and the calculator subtracts it from your max allowable offer, showing the highest price you can put a property under contract for while still leaving room for your spread and your end buyer's profit.
