How to Analyze a Rental Property
The three metrics that matter most when evaluating any investment property.
Net Operating Income (NOI)
NOI is your effective gross income minus all operating expenses — before the mortgage. A positive NOI means the property covers its own costs. Divide by the purchase price to get the Cap Rate.
Cash-on-Cash Return
CoC measures annual cash flow divided by your total cash invested (down payment + closing costs). A CoC of 6–8%+ is generally considered a solid return for a rental property.
Debt Service Coverage Ratio
DSCR = NOI ÷ Annual Mortgage Payment. Lenders typically require 1.25x or higher. A DSCR below 1.0 means the property doesn't generate enough income to cover the mortgage.
