After-Repair Value (ARV) Calculator
Estimate a property's After-Repair Value from comparable sales, apply the 70% Rule, and find your Maximum Allowable Offer — in seconds.
Comparable sales
Enter a few recently sold, renovated homes near your property. We average their price per square foot.
Your property
Add at least one comparable sale and your square footage.
Rehab & your offer
The 70% Rule: a flip offer should stay at or below 70% of the After-Repair Value, minus your rehab budget.
This is an estimate based on the numbers you entered. A real After-Repair Value comes from current, verified comparable sales — not a single rule of thumb. Always confirm with a full Comparative Market Analysis before making an offer.
Skip the manual comp hunt
Fundry pulls matched comparable sales for any Georgia address and builds the After-Repair Value for you — flip, ground-up, or rental. Free.

The calculator above works when you already have the comparable sales in hand. Finding them is the slow part — digging through recent sales, checking which ones were actually renovated, and working out the price per square foot one comp at a time.
Fundry does that step for you on any Georgia address. Type the address, pick your strategy — flip, ground-up, or rental — and Fundry pulls matched comparable sales and builds the resale estimate. Live Multiple Listing Service (MLS) listings are pulled at search time — not from a stale database. You curate which homes count, and the estimate and profit recalculate live. No black box. Buying in a city you don't drive every day? Check the market data for the Georgia city you're buying in.
And it works while you browse, not just when you type an address. Scroll the map, tap a pin — an active listing or an off-market house — and the same flow runs: the comparable sales are pulled, the resale estimate builds, and the comps stay yours to curate. One analysis, any Georgia address — on-market or off.

How to calculate ARV
After-Repair Value (ARV) — also called after-renovation value — is the price a home should fetch once it's fully renovated. The price-per-square-foot method is the one most investors trust, and it's exactly what the calculator above runs:
- Pull three to six recently sold, renovated homes near your subject property.
- Divide each sale price by its square footage to get a price per square foot.
- Average those price-per-square-foot figures.
- Multiply the average by your property's post-renovation square footage.
Illustrative example. Say three renovated homes near your subject property recently sold at $205, $220, and $235 per square foot. The average is $220 per square foot, and your property will be 1,400 square feet after the renovation:
$220 × 1,400 sqft = $308,000 estimated ARV
Apply the 70% Rule with a $40,000 rehab budget:
($308,000 × 70%) − $40,000 = $175,600 Maximum Allowable Offer
Offer more than $175,600 and the difference comes out of your profit. And if your comps disagree wildly — $180, $220, and $260 per square foot, say — that spread is a warning: tighten the comp set before you trust the average.
The result is your estimated ARV. The closer your comparable sales are in size, age, condition, and location, the more reliable that number will be.
The 70% Rule and your Maximum Allowable Offer
Once you have an ARV, the 70% Rule gives you a fast ceiling on what to offer for a flip:
Maximum Allowable Offer = (ARV × 70%) − rehab cost
The 70% buffer is meant to cover holding costs, financing, closing costs, and your profit. Some investors use 75% in hotter markets or 65% when they want more cushion. It's a screening tool — a full analysis still pays off before you commit. Read the full guide: the 70% Rule explained.
ARV vs. a full Comparative Market Analysis (CMA)
A single ARV number is only as good as the comps behind it. A full Comparative Market Analysis (CMA) goes further: it weighs each comparable sale by how similar it really is, accounts for recency and distance, and adapts to your strategy — flip, ground-up, or rental. That's the difference between a rule of thumb and a number you'd stake an offer on.

Frequently asked questions
What is After-Repair Value (ARV)?+
After-Repair Value (ARV) is what a property could realistically sell for once renovations are complete. Investors use it to decide how much to pay today: the ARV sets the ceiling, and the purchase price plus rehab budget have to leave room for profit underneath it.
How do you calculate ARV?+
The most common method is price per square foot. Take three to six recently sold, renovated homes near your property, divide each sale price by its square footage to get a price per square foot, average those figures, then multiply by your property’s square footage after renovation. That product is your estimated ARV.
What is the 70% Rule?+
The 70% Rule is a quick screen for flips. It says your offer should stay at or below 70% of the After-Repair Value, minus your estimated rehab cost. As a formula: Maximum Allowable Offer = (ARV × 70%) − rehab. Some investors adjust the percentage up or down based on the deal and the market.
What is a Maximum Allowable Offer (MAO)?+
The Maximum Allowable Offer is the most you can pay for a property and still hit your target profit after rehab, holding, and selling costs. The 70% Rule is the fastest way to approximate it, but a full analysis also accounts for financing, holding time, and closing costs.
How many comparable sales do I need?+
Aim for at least three to six recent sales of similar, renovated homes within about a mile of your property. The closer the comps are in size, age, condition, and location, the more reliable your ARV. Fewer or older comps mean a wider margin of error.
Is this ARV calculator free?+
Yes. The calculator is completely free and requires no sign-up. If you want Fundry to pull the comparable sales for you on any Georgia address and build the After-Repair Value automatically, you can create a free account.
Is after-renovation value the same as ARV?+
Yes. After-renovation value is another name for After-Repair Value (ARV) — investors and lenders also say post-repair value. Whatever the name, the calculation is identical: the price the property should sell for once the renovation is complete.
