How to use it
The mid ARV is the most defensible single number. The low ARV is the conservative figure flippers should underwrite to. The high ARV is the upside target if comps run hot.
PSF-based ARV ignores condition and amenity differences. Always pair with line-item adjustments for major features (lot, view, garage, ADU, basement) and use comps that match the post-renovation finish level you'll deliver.

How this calculator works
What this page estimates
This After-Repair Value per Square Foot Calculator is built to give a quick, browser-based estimate for after-repair value per square foot. Build ARV from the average price-per-square-foot of comparable sold properties. Returns low, mid, and high ARV ranges plus a dollar adjustment line for material differences. The inputs stay on the page during normal use, and the result should be treated as an estimate for planning, comparison, or education rather than professional advice.
Calculation approach
The calculator applies the standard relationship implied by the inputs, then formats the answer so it can be checked and reused. For finance tools, the most important step is using consistent units, rates, time periods, and assumptions before comparing the result with another calculator or outside quote.
Example workflow
For example, start with a realistic value you already know, change one input at a time, and watch how the answer moves. That makes it easier to tell whether the result is being driven by the main amount, the rate, the time period, or a unit conversion.
Practical checks
- Use current, real-world numbers when the result affects money, health, tax, or legal decisions.
- Run a low, base, and high case when the inputs are estimates.
- Check the related calculators below when the next decision depends on a different assumption.
How to interpret the after-repair value per square foot result
Best use
Use the result as a planning number for comparing payments, rates, returns, tax reserves, or cash-flow choices before you request a quote or make a commitment.
Cross-check
Compare the answer with the contract, lender estimate, tax form, brokerage statement, payroll record, or invoice that will control the real-world outcome.
Watch for
Do not rely on a single optimistic rate, return, or fee assumption. Money pages work best when you run low, base, and high cases and keep professional advice separate from the estimate.
This page belongs to the Finance calculator library, so the answer should be read in the context of the decision you are modeling rather than as a universal rule.
Before relying on this after-repair value per square foot estimate
Most calculator mistakes come from the inputs, not the arithmetic. Use this short audit before you reuse the answer in a spreadsheet, quote, application, or important conversation.
Confirm source numbers
Match balances, rates, fees, taxes, income, and payment dates against the lender quote, payroll record, tax form, statement, invoice, or contract.
Separate cash flow from total cost
A lower monthly payment can still cost more over time if fees, interest, taxes, or a longer term are hidden in the structure.
Run conservative cases
Test at least one higher-cost or lower-return case before using the output for a purchase, refinance, investment, loan, or tax decision.
Rerun this page when the rate, price, term, fee, tax rule, income, expense, or expected holding period changes.
How to Use
- Enter the subject property's square footage (after any additions if applicable).
- Enter price and square footage for up to 3 sold comps that match the post-renovation quality you'll deliver.
- Enter a dollar adjustment for differences (better lot, view premium, condition gap, ADU, etc.).
- Read the mid ARV for underwriting; use the low ARV as the conservative target.
Frequently Asked Questions
How do I pick comps for ARV?
Recently sold (last 90–180 days), within 0.5 mile of the subject, similar square footage (±20%), similar bed/bath count, and most importantly similar finish level to what you'll deliver post-renovation. A flipped comp is more relevant than a tired comp.
Should I use list price or sold price?
Sold price. List prices reflect seller hopes; sold prices reflect what buyers paid. If your area has fast price changes, a list-price comp can be useful for trend, but underwrite to actual sales.
What's a good adjustment?
Most adjustments fall in $5,000–$30,000 ranges per material feature. Bigger lot, view, finished basement, garage, ADU all warrant explicit dollar adjustments rather than rolling into PSF.
How conservative should I be?
Underwrite flips to the low ARV, not the mid or high. Markets soften, comps you didn't see surface, and your finish quality may not match the highest comp. The low ARV is your safety margin.
