How to Calculate ARV Without Fooling Yourself

Every flip offer, every wholesale number and every rehab loan starts with one figure: the after repair value.

Get it right and a lot of mistakes become survivable. Get it wrong and nothing else matters. Perfect repair estimates and tight contractor management can’t fix a house that was never going to sell for what you thought.

I’m Ben Lovro, an investor based in Lexington, SC, and the first question I ask on any deal is, “What does this sell for when it’s done — and can you prove it?” Here’s how to answer it.

What ARV actually is

After repair value is what the property should sell for, on the open market, once it’s renovated to the level that comparable renovated homes in the area are selling at.

Three things in that definition matter:

1. On the open market. Not to a friend, not in a perfect world, not in an auction.
2. Renovated to the level of the comps. Not to your taste, and not beyond what the neighborhood supports.
3. Comparable renovated homes. ARV comes from sales of houses that were already fixed up, not from the unrenovated ones.

ARV is not what an online estimate says. It’s not what the seller thinks. And it’s not the price on the nicest listing in the zip code.

Step 1: start with sold comps

Active listings tell you what people hope to get. Pending sales tell you what someone agreed to. Sold comps tell you what actually happened. Build your ARV from sold.

My comp filters, briefly: recent closings, close by, same school zone, no highway or rail line between, matching bed and bath count, similar size within ±20%, similar age, style and stories, and at least three. Each rule has a reason, and I explain all of them on how to pull comps.

Then add one more filter for ARV specifically: condition. You want comps that were renovated or are in comparable updated condition — the house you’re going to create, not the house you’re buying.

Step 2: study each comp like a detective

Pulling three addresses isn’t the job. Understanding them is.

For each comp, look at:

• Listing photos. What was the finish level? Kitchen, baths, flooring, fixtures.
• Days on market. Fast sales suggest strong demand at that price. Long ones suggest it was a stretch.
• Price changes. Did it sell at the original list price or after reductions?
• Concessions. Did the seller pay toward the buyer’s closing costs? That can inflate the recorded price.
• Lot and location. Corner lot? Backs to a busy road? Cul-de-sac?
• Extras. Garage, carport, finished basement, pool, outbuildings, extra lot.

You’re building a picture of what buyers paid for — and what they didn’t.

Step 3: adjust for real differences

No comp is identical. So you adjust — carefully, and only for differences that matter to buyers in that area.

Common adjustment categories:

How much to adjust? That’s local knowledge. Talk to a listing agent you trust who sells renovated homes in that area, look at paired sales (two similar houses that differ in one feature), and over time you’ll learn what buyers in your market actually pay for. Don’t invent precision you don’t have. A sloppy adjustment can hide a bad deal.

Step 4: build a range, not a point

Once your comps are adjusted, you’ll see them cluster. That cluster is your range.

I write ARV as a band with three marks:

• Conservative — the low end of the well-supported cluster.
• Likely — where most of your best comps land after adjustments.
• Optimistic — the high end, usually supported by one or two sales.

Then I underwrite the deal at the conservative-to-likely end. If the deal only works at optimistic, it doesn’t work. Markets shift during renovations, appraisals come in tight, and buyers negotiate. Leave room.

Step 5: sanity-check the result

Before you trust your ARV, pressure-test it:

If you can’t answer yes to most of these, tighten the number or get more data.

How ARV flows into your offer

Once you trust your ARV, it drives the rest of the analysis:

• Flips: MAO = (ARV × 0.70) − repairs. The 70 percent rule page explains what that cushion has to cover.
• Selling to another investor: subtract your fee too, so the deal still works at the buyer’s numbers.
• Rentals: ARV matters for refinancing and equity, but rent and expenses drive the decision. See the BRRRR method for why a refinance depends on an honest ARV.

Every exit’s formula is collected in maximum allowable offer formulas.

ARV mistakes I see constantly

• Using an automated online estimate. It doesn’t know the condition of your house or of the houses it compared it to.
• Crossing boundaries. A sale across a highway or in a different school zone can be a very different market.
• Ignoring the finish level. If your comps had high-end finishes and you’re planning a modest refresh, your ARV is too high.
• Using old sales in a moving market. A sale from a different market cycle can mislead you in either direction.
• Believing the seller. Sellers usually know what one neighbor got. They rarely know why.

Local knowledge matters

ARV is hyper-local. In the Midlands, two streets can feel like different markets because of a school zone line, a busy road, or the age of the housing stock.

Your next step

Pick one renovated house that recently sold in your area. Pretend you’re underwriting it before it was renovated. Pull comps, adjust them, build a range — then compare your range to the actual sale. Do this five times and your ARVs will start getting sharp.
