Estimate a renovated property's value from three visitor-entered comparable values and adjustments.
It keeps income, operating costs, financing, invested cash, value, timing, and exit assumptions explicit so you can reproduce the result and compare genuinely consistent scenarios.
Calculation structure
Keep income, costs, and value in the right period
Adjusted comparable = comparable value + signed adjustment. Estimated ARV = average of the three adjusted comparable values.

Read the result correctly
Use the result with its boundaries
Adjusted comparable values of 300,000, 310,000, and 320,000 average to an estimated ARV of 310,000.
Comparable selection and adjustments require valuation judgment. This arithmetic does not appraise a property or calculate a maximum offer.
Quick guide
How to use this calculator
Enter property amounts from one consistent currency and period.
Use the labels to match the calculator's stated income, cost, area, or capacity convention.
Read the assumptions beside the result before using it in an investment comparison.
Calculation method
Calculation method
Adjusted comparable = comparable value + signed adjustment. Estimated ARV = average of the three adjusted comparable values.
Entered fixed decimals use exact rational arithmetic. Money rounds only for display; a supported nonzero amount is never replaced by a misleading zero.

Supported inputs
Precision and limits
Visible input limits
Amounts accept up to 30 digits and 12 decimal places and are capped at 1e12 per input. Rates are capped at 1000%; signed value-change rates cannot be below −100%.
International scope
No currency, tax regime, tenancy law, lender threshold, local market database, appraisal standard, or jurisdiction-specific fee is assumed.
Decision boundary
The result is an arithmetic scenario based on visitor-entered figures, not an appraisal, forecast, lending decision, legal determination, or investment recommendation.
Calculator-specific assumptions
Comparable selection and adjustments require valuation judgment. This arithmetic does not appraise a property or calculate a maximum offer.
