Cap rate compares properties, it does not value them alone

Cap rate is NOI divided by value. It deliberately excludes financing, so two buyers with different loans can compare the same building on the same basis.

It is only as good as the NOI behind it. A cap rate built on an owner's optimistic expense estimate — no vacancy, no management fee, no reserves — is not comparable to one built on real numbers.

What belongs in operating expenses

  • Property taxes
  • Insurance
  • Repairs and maintenance
  • Management fee, even if you self-manage
  • Utilities you pay
  • HOA dues
  • Vacancy allowance
  • Reserves for capital items

Mortgage principal and interest, depreciation, and capital improvements are excluded from NOI.

Frequently asked questions

What is a good cap rate?
It is entirely market and asset dependent. Compare against recent sales of similar properties in the same submarket rather than a national benchmark.
Should I include a management fee if I manage it myself?
Yes. Your time has a cost, and any future buyer will price the property with management included.
