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.
- 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.
