ARV Calculator

Estimate after-repair value (ARV) by blending recent comparable sales and translate that value into a max allowable offer using the 70% rule or your own custom ratio.

ARV and offer ladder

ARV is the blended adjusted price per square foot applied to the subject's square footage. Treat it as a range, not a precise number.

The 70% rule is a classic flipper heuristic: buy for no more than 70% of ARV minus rehab so the project can absorb closing costs, holding, realtor fees at resale, and a margin for the investor. BRRRR investors often use 75–80% because cash flow covers holding costs once stabilized.

How this calculator works

What this page estimates

This ARV Calculator is built to give a quick, browser-based estimate for arv. Estimate after-repair value (ARV) by blending recent comparable sales and translate that value into a max allowable offer using the 70% rule or your own custom ratio. 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 arv 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 arv 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

  1. Enter the subject property's square footage and your planned rehab budget — ARV and max offer both depend on both.
  2. Add up to four recent comparable sales with sale price and square footage. Use comps of similar age, size, and condition.
  3. Apply a positive adjustment when the comp is worse than the subject or a negative adjustment when the comp is better.
  4. Review the blended average and median ARV — use the median when one comp looks like an outlier.
  5. Compare the 70% rule max offer with the custom offer ratio you run before sending an offer letter.

Frequently Asked Questions

What is ARV?

ARV stands for after-repair value. It is an estimate of what the property will sell or appraise for after your planned rehab, based on recent comparable sales of similar properties in similar condition.

How is ARV calculated?

This calculator averages the adjusted price per square foot across your comps, then multiplies that blended value by the subject property's square footage. It also shows a median-based ARV to reduce the effect of outliers.

What is the 70% rule?

The 70% rule is a common flipper heuristic: pay no more than 70% of ARV minus rehab. The buffer covers closing costs on both sides, holding costs during the project, realtor fees at resale, and a profit margin for the investor.

Should BRRRR investors use 70%?

BRRRR investors often use 75–80% of ARV because they hold instead of flip, which means cash flow covers holding costs and rehab risk is spread over a longer period. The right ratio depends on rehab complexity, refinance appraisal risk, and the investor's cash flow target.

How do I pick comps?

Use recent sales — ideally within 3–6 months — of homes with similar size, bedrooms, bathrooms, age, lot, and condition within the same neighborhood. The closer the match, the less you have to adjust and the tighter the ARV estimate.
