How to Calculate ARV: The Investor's Step-by-Step Guide (2026)

To calculate ARV, multiply your property's square footage by the average price per square foot of recently sold comparable homes in the same area. For example: 1,200 sqft x $150/sqft = $180,000 ARV. Always use sold comps from the last 6-12 months within a half-mile radius.

If you've ever made an offer on a fixer-upper and felt like you were guessing, you're not alone. ARV is the number that makes or breaks a deal, and most investors either skip the math entirely or do it wrong. This guide walks you through exactly how to calculate ARV the right way, with real numbers, real examples, and the mistakes you need to avoid before you ever submit an offer.

What Is ARV?

ARV stands for After Repair Value. It's the estimated market value of a property after all repairs and renovations have been completed. Think of it as your target number - the ceiling price the property can realistically sell for once it's in retail condition.

ARV is used in almost every investment strategy:

Wholesalers use it to calculate their maximum allowable offer (MAO)
Fix and flip investors use it to determine if a deal pencils out
Hard money lenders use it to underwrite loans (usually lending 65-70% of ARV)
BRRRR investors use it to plan their refinance exit

Without an accurate ARV, every other number in your deal analysis is just noise. Check out our ARV glossary for a deeper look at how ARV fits into the full investment picture.

The ARV Formula

The formula itself is simple. The hard part is getting the inputs right.

ARV = Average Price Per Square Foot of Comps x Subject Property Square Footage

Example: $150/sqft x 1,200 sqft = $180,000 ARV

Step-by-Step ARV Calculation (With Real Numbers)

Step 1: Define the Subject Property

Let's say you're looking at a 3-bedroom, 2-bathroom ranch-style home built in 1988, with 1,200 square feet of living space in a suburban zip code.

Step 2: Find Comparable Sales (Comps)

Comp 1: 1,150 sqft, sold for $168,000 = $146/sqft
Comp 2: 1,220 sqft, sold for $187,000 = $153/sqft
Comp 3: 1,190 sqft, sold for $176,000 = $148/sqft
Comp 4: 1,250 sqft, sold for $196,000 = $157/sqft

Average PSF: ($146 + $153 + $148 + $157) / 4 = $151/sqft

Step 3: Apply the Formula

$151/sqft x 1,200 sqft = $181,200 ARV

Step 4: Run Your Deal Numbers

$180,000 x 0.70 = $126,000 minus estimated rehab costs of $30,000 = $96,000 Maximum Allowable Offer

Common ARV Mistakes That Kill Deals

Using the wrong comps is the number one reason investors overpay for properties. Pulling active listings instead of sold properties, using distressed sales, or including homes with major differences in condition or square footage will inflate or deflate your ARV and lead to bad offers.

When you're unsure about a comp, ask yourself: "Would a retail buyer compare this property to my subject when shopping?" If the answer is no, don't use it.

FAQ

What is ARV?

ARV (After Repair Value) is the estimated market value of a property after it has been fully renovated to retail condition. It's used by investors, wholesalers, and lenders to evaluate deal potential and set offer prices.

How do you find comps for ARV?

Comps are found by searching for recently sold properties (last 6-12 months) that are similar in size, type, bed/bath count, and condition to your subject property, located within a half-mile radius. The MLS is the most reliable source, but tools like DealBeast, Zillow, and Redfin can surface solid comps quickly.

What's the difference between ARV and current value?

Current value (or as-is value) is what the property is worth right now in its current condition. ARV is what it will be worth after renovations are complete. The gap between these two numbers, minus rehab costs, is where your profit potential lives.

How accurate is ARV?

ARV is an estimate, not a guarantee. Accuracy depends heavily on comp quality, local market conditions, and how realistic your renovation scope is. A well-pulled ARV using clean, similar comps is typically within 5-10% of the eventual sale price.

Can I calculate ARV without MLS access?

Yes. Public data sources like Zillow, Redfin, and county assessor records can provide sold comp data. DealBeast aggregates multiple data sources to give you MLS-quality ARV analysis without requiring an agent license or MLS subscription.
