What will it sell for, fixed up?
THE SHORT ANSWER
After-repair value (ARV) is what a property sells for once it's fully fixed up, and the fastest way to estimate it is sold-comp price per square foot times your property's square footage. Enter up to three recent solds below and this calculator gives you a low, middle, and high ARV instantly.

How the price-per-square-foot method works
Every sold comp tells you what buyers paid per square foot for a finished house in that pocket. Divide each comp's sold price by its square footage, then multiply by YOUR property's square footage:
ARV = comp $/sqft × your sqft
With two or three comps you get a band instead of a single guess: the cheapest comp sets the low end, the average sets your working estimate, the strongest sets the ceiling. That band is what this calculator computes — the same $/sqft translation PropTitan runs when it comps an address for you.
Worked example
Your target property is 1,450 sqft. Three renovated solds nearby:
comp 1 $265,000 ÷ 1,400 sqft $189/sqft
comp 2 $248,000 ÷ 1,350 sqft $184/sqft
comp 3 $279,000 ÷ 1,500 sqft $186/sqft
average ≈$186/sqft
× your 1,450 sqft ≈$270,000
Average is about $186/sqft, so the working ARV is $186 × 1,450 ≈ $270,000, inside a band of roughly $267,000–$274,000. A band that tight means the comps agree — you can quote that ARV to a buyer with a straight face.
Where $/sqft goes wrong
Price per square foot flattens everything into one number, so it misses lot size, garages, pools, one-story vs two-story, and street-by-street differences. It also skews when comp sizes differ a lot from the subject — small houses carry higher $/sqft than big ones. Keep comps within about 20% of your property's size, in the same school zone or subdivision when you can, and sold within the last 6 months. For anything you're actually going to contract, follow up with a full comp review — photos and condition, not just math.

QUESTIONS
Calculator questions
What counts as a good comp for ARV?
A recently SOLD house — not an active listing — near the subject, similar in size, age, bed/bath count, and renovated to the condition your property will be in after the rehab. Closer, more recent, and more similar always beats more comps.
How many comps do I need?
Three solid solds beat ten loose ones. This calculator takes up to three; if the three of them land far apart, that spread is telling you the comps aren’t truly comparable — tighten the criteria before trusting the number.
Why does the calculator show a range instead of one number?
Because ARV is an estimate, not a fact. The low end uses your cheapest comp’s price per square foot, the high end your strongest. Underwrite the deal on the low-to-middle band and let the high end be upside, not the plan.
Can I use Zillow’s Zestimate as the ARV?
Not on a distressed deal. Automated estimates price the house in its CURRENT condition and lag renovations. ARV is a post-rehab number — it has to come from renovated solds, which is exactly what the comp method gives you.
Do I need MLS access to find sold comps?
No. County records and the big listing portals show sold prices in most states, and PropTitan pulls sold comps for any address automatically — with side-by-side photos so you can judge condition, not just numbers.
