How to estimate after-repair value (ARV)

After-repair value is what a property should sell for once the work is finished. Most investors estimate it from recent sales of similar renovated homes nearby. Here is the method, a worked example and how ARV feeds your offer.

What is ARV?

After-repair value (ARV) is the price a property should sell for once the planned renovation is complete. It is the most important number in a flip or BRRRR, because your maximum offer, your profit and your refinance all start from it.

How do you estimate ARV?

  1. Find comparable sales (comps). Look for homes that closed recently, nearby, in renovated condition, and similar in size, age, bedrooms and bathrooms.
  2. Work out each comp's price per square foot. Sale price ÷ living area.
  3. Adjust for differences. An extra bathroom, a garage, a larger lot or a busy road all move value.
  4. Apply the result to the subject. Average adjusted price per square foot × the subject's square footage.

A worked example

Three renovated comps near a 1,500 square foot subject:

CompSizeSale pricePrice per sq ft
Comp 11,500 sq ft$300,000$200
Comp 21,600 sq ft$312,000$195
Comp 31,450 sq ft$297,250$205
Average$200

ARV ≈ 1,500 × $200 = $300,000.

Which comps should you trust?

  • Closed sales over listings. Asking prices are hopes; closed prices are evidence.
  • Recent over old. In a moving market, a sale from a year ago may be out of date.
  • Close over far. School zones, busy roads and neighborhood edges all change value.
  • Same condition. Compare your finished house with other renovated houses, not with fixer-uppers.

How does ARV turn into an offer?

The 70% rule is the usual starting point: maximum offer = ARV × 70% − rehab. With a $300,000 ARV and a $45,000 rehab, that is $165,000. Then check the full profit, including buying, holding, financing and selling costs. The fix and flip guide walks through that calculation.

How sensitive is a deal to ARV?

Very. In the fix and flip guide's example, the break-even sale price was $250,323, so ARV could fall about $49,700 before the deal lost money. If your profit depends on the highest comp, treat the deal as risky and test a lower ARV.

Common ARV mistakes

  1. Using listings instead of closed sales.
  2. Comparing across neighborhoods or school zones.
  3. Ignoring condition. Your renovation has to match the comps you used.
  4. Assuming a flat market through a long rehab.

Questions people ask

Three is a common minimum. Closer, more recent and more similar sales are worth more than a larger number of weak ones.
