Free Property Valuations NOI Calculator (2026)
Determine fair market value using the income approach
Why Property Valuations Matters
The income approach to property valuation relies entirely on NOI to determine what an investment property is worth. This calculator enables agents to perform quick yet defensible property valuations by computing NOI and applying local cap rates. Whether you're preparing a listing price recommendation, helping a buyer justify an offer, or advising a client on portfolio valuation, accurate NOI calculations are the foundation of credible income-property appraisals.

Tips & Best Practices
Use at least three comparable property cap rates from recent sales to validate your valuation conclusion
Present valuations using a range of cap rates rather than a single point estimate to show the sensitivity of the analysis
Distinguish between in-place NOI valuation and pro forma NOI valuation so clients understand current vs potential value
Cross-reference your NOI-based valuation with price-per-unit and price-per-square-foot metrics for multifamily properties
Frequently Asked Questions
Research recent sales of comparable income properties in your area and calculate their cap rates (sale price divided by NOI at time of sale). Commercial real estate databases, local brokerages, and appraisal reports are good sources. Cap rates vary by property type, location, condition, and market cycle, so use properties as similar as possible to the subject.
Property value equals NOI divided by cap rate. A higher NOI means a higher value; a lower cap rate also means a higher value (since investors accept lower returns in safer markets). For example, a property with $100,000 NOI in a 7% cap rate market is worth approximately $1.43 million, while the same NOI in a 5% cap rate market is worth $2 million.
While NOI calculations apply to any income property, single-family rentals are typically valued using comparable sales (market approach) rather than the income approach. However, calculating NOI for single-family rentals is still valuable for analyzing investment returns, evaluating cash flow, and comparing opportunities. Investors with larger single-family portfolios increasingly use NOI-based analysis.
