ARV Calculator

After-repair value sets the size of your loan, your max offer and your profit. This calculator estimates ARV the way investors do it on the back of a napkin: price per square foot from recent sold comps, applied to your property after the rehab.

ARV Calculator. Estimate after-repair value from sold comps: price per square foot for each comp, an average- and median-based ARV, the low-to-high range, and a 70% rule max offer.

How the ARV calculator works

  • Adjusted comp price = sale price plus or minus your adjustment for differences (garage, bedroom count, condition, lot).
  • $ per sq ft = adjusted price ÷ the comp’s living area.
  • ARV = your property’s living area × the average $ per sq ft. The median-based ARV is shown as a check against one outlier comp.
  • Range = your living area × the lowest and highest comp $ per sq ft.
  • Max offer = ARV × 70% − rehab budget (the 70% rule; change the percentage to match how you buy).

Worked example

The calculator opens with this example. Your property will be 1,500 sq ft after repairs. Four nearby sales came in between about $182 and $186 per sq ft: $285,000 for 1,550 sq ft, $270,000 for 1,450, $299,000 for 1,620 and $255,000 for 1,400. The average is about $184 per sq ft, so ARV is about $276,296, with a range of $273,214 to $279,310. With a $50,000 rehab, the 70% rule puts your max offer at about $143,407.

This is an estimate for discussion purposes only, not an appraisal. Any Ternus loan is subject to Ternus’s own valuation, underwriting and final approval.

ARV questions

What makes a good comp?

A recent sale (ideally the last six months), close by, similar in size, age, bedroom and bathroom count, and finished to the level you plan to renovate to. Three to five good comps beat ten loose ones.

Why use price per square foot?

It puts homes of different sizes on the same scale. It works best when the comps are close in size to your property; very large or very small comps can skew it, which is why the median and the range are shown too.

How do lenders use ARV?

Fix-and-flip lenders often cap the loan at a percentage of ARV. Ternus confirms value through its own valuation process, so use this estimate to screen deals and set your offer, then price the loan in the Loan Sizer.
