Quick answer: ARV stands for After Repair Value – what a property will be worth once it’s fully renovated, not what it’s worth today. You calculate it by pulling 3-5 recent comparable sales of similarly renovated homes nearby, adjusting each one for differences in size, condition, and features, then averaging the adjusted numbers. That average is your ARV, and it’s the single figure everything else in a flip, your max offer, your rehab budget, your exit profit, gets built on top of.
Get the ARV wrong and it doesn’t matter how good the rest of your math is. Overestimate it and you’ll pay too much for the property or budget too much for rehab, eating into a profit margin that was never really there. Underestimate it and you’ll pass on deals that actually would’ve worked. Either way, ARV is the number the rest of your deal analysis stands on, which makes it worth understanding properly instead of eyeballing it.
Here’s the thing, a lot of people either guess at ARV based on gut feeling, or they pull one number off Zillow’s Zestimate and call it a day. Neither is a real methodology. What follows is the actual process appraisers and experienced investors use, broken down step by step.
What Is ARV?
ARV, or After Repair Value, is the estimated market value of a property once renovations are complete, the price it would realistically sell for in its improved condition, based on what similar renovated homes nearby have actually sold for. It’s different from a property’s current “as-is” value, which reflects what it’s worth today, repairs and all. The gap between those two numbers is where a flipper’s profit potential lives.
How to Calculate ARV: The Comps Method
This is the same sales comparison approach licensed appraisers use, just applied specifically to a property’s future, renovated state rather than its current one.
Step 1: Find 3-5 Recent Comparable Sales
Pull sold listings (not active listings: asking price isn’t the same as what a buyer actually paid) from the last 3-6 months, within about a half-mile of your subject property if possible. You want homes that are already renovated or in similar target condition to what yours will be once you’re done, not homes in their current, unrenovated state.
Step 2: Adjust for Differences
No two houses are identical, so each comp needs adjusting to account for what makes it different from your subject property: square footage, bedroom and bathroom count, lot size, and overall condition. If a comp is 200 square feet smaller than your property, you’d adjust its sale price upward using a reasonable price-per-square-foot figure for that market. Same logic applies in reverse for bedrooms, bathrooms, and any features your property will have that the comp doesn’t.
Step 3: Average the Adjusted Values
Once each comp has been adjusted, average them together. That average is your ARV. If your adjusted comps are landing in a tight range, say within $10,000-$15,000 of each other, that’s a good sign your estimate is reliable. If they’re all over the place, it usually means your comps aren’t similar enough to your subject property and you need better ones.
The ARV Formula
Stated simply, the process above breaks down to:
ARV = Average of (Comp Sale Price + Adjustments for Size, Condition, and Features)
There’s no shortcut formula that skips the comps, anything claiming to calculate ARV from a single input (square footage alone, or a flat multiplier on current value) is giving you a rough guess, not a real number. The formula only works because of the comp research feeding into it.
Common ARV Mistakes
A few things that quietly wreck an otherwise solid ARV estimate:
Using listing prices instead of sold prices. A house that was listed at $320,000 might have actually sold for $295,000 after negotiation. Only sold prices reflect real market value.
Comps that are too far away or too old. A comp from 8 months ago in a fast-moving market, or one from two neighborhoods over, isn’t really comparable anymore, even if the house itself looks similar on paper.
Ignoring condition differences. Comparing your fully renovated flip to a comp that sold with a dated kitchen and original bathrooms will inflate your ARV if you don’t adjust for that gap.
Not enough comps. A single comp is an opinion. Three to five gives you an actual data set you can average and sanity-check against each other.
How ARV Connects to Your Offer
Once you have a solid ARV, it becomes the anchor for figuring out your maximum offer. The traditional guideline here is the 70% rule — offer no more than 70% of ARV, minus your estimated repair costs. That rule has been the industry shorthand for years, and it’s still a useful starting reference point.
That said, it’s worth being honest about current market conditions: with material costs, labor, and financing costs all running higher than they were when the 70% rule became conventional wisdom, actually landing a deal at 70% of ARV minus repairs is a lot harder to pull off than it used to be. Plenty of experienced investors are finding they need to flex that percentage upward on a case-by-case basis, or get more aggressive on the rehab estimate side, to make deals pencil out at all. Treat 70% as a reference point to sanity-check against, not a hard rule you’ll hit on every deal in this market.
Once you’ve got your ARV and a realistic target percentage, our Max Offer Calculator takes both of those inputs, along with your rehab estimate, and does the rest of the math for you.

Common Questions on Real Estate ARV
What does ARV mean in real estate?
ARV stands for After Repair Value — the estimated market value of a property once renovations are complete, based on what comparable renovated homes nearby have actually sold for.
How do you calculate ARV?
Pull 3-5 recent comparable sales of similarly renovated properties near your subject property, adjust each one for differences in size, condition, and features, then average the adjusted values. That average is your ARV.
What is the ARV formula?
ARV equals the average of your adjusted comparable sale prices, where each comp is adjusted up or down based on how it differs from your subject property in size, condition, and features. There’s no valid shortcut formula that skips the comp research itself.
How does ARV affect the cash offer I receive as a seller?
If you’re a homeowner rather than an investor, ARV is part of what a cash buyer uses behind the scenes to calculate the offer they extend to you — they estimate what your home will be worth once repaired, subtract their rehab costs and margin, and arrive at a number. If you’re curious how that process actually works from the buyer’s side, Yes I Pay Cash has a breakdown of how their offer calculation process works, and Keys to Your Property has a comparison of cash home buyer companies in Maryland if you’re weighing multiple options.
Once you’ve got a reliable ARV for a property, the rest of your deal analysis gets a lot more solid. Plug your number into the Max Offer Calculator to see exactly what you should be offering.
