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.

Average price per square foot

Your property

Estimated After-Repair Value

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.

Maximum Allowable Offer

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.

How to calculate ARV

After-Repair Value (ARV) 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:

  1. Pull three to six recently sold, renovated homes near your subject property.
  2. Divide each sale price by its square footage to get a price per square foot.
  3. Average those price-per-square-foot figures.
  4. Multiply the average by your property's post-renovation square footage.

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.

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?+
