Common questions

What does cap rate mean?

Cap rate measures net operating income relative to price or basis. It is a quick signal for how efficiently a property produces income.

Is cap rate enough to buy a property?

No. Cap rate is a useful filter, but you still need to understand financing, repairs, reserves, and actual monthly cash flow.

Why compare cap rate with NOI?

Because cap rate comes from NOI. Looking at both keeps you honest about whether the income quality supports the valuation.
