Plain-English investing term

What Is Cap Rate in Real Estate?

Cap rate is annual NOI divided by property value or purchase price. It estimates the property's unlevered income yield before your financing choices.

Why it matters

Cap rate helps compare income-producing properties without letting one investor's loan terms distort the property-level view. It is useful, but it is not the whole deal. A property can have a decent cap rate and still be a bad fit if financing, repairs, or risk are ugly.

PropLurk take: Cap rate is a flashlight, not a verdict. It shows one part of the room. You still need to check the floor before walking in.

Cap-rate quick math
  • Annual NOI: $18,500
  • Purchase price: $250,000

Result: $18,500 / $250,000 = 7.4% cap rate

Usually include

  • Annual NOI
  • Purchase price or current value
  • Stabilized NOI if clearly labeled
  • A consistent value basis

Do not mix in

  • Mortgage payment
  • Down payment
  • Appreciation
  • Tax benefits

Common ways investors mess this up

  • Using gross rent instead of NOI
  • Comparing current NOI on one property with pro-forma NOI on another
  • Assuming high cap rate always means good deal
  • Ignoring condition and tenant quality

How PropLurk uses it

PropLurk shows cap rate alongside cash-on-cash return, DSCR, and cash flow so you do not mistake one clean percentage for the full decision.

This guide is educational and does not provide investment, lending, tax, legal, or appraisal advice. Verify the specific property, lender, and local rules before making decisions.

Calculate cap rate inside the full deal record.

PropLurk keeps the definition, formula, assumptions, offer, and decision record connected so the number does not get lost in another spreadsheet.
