How we calculate the cap rate, and how accurate it is

Cap rate = NOI ÷ price. NOI is the rent you would collect in a year, after vacancy, minus the costs of running the property. The loan is left out, so the cap rate measures the property as if you paid cash.

Amounts are rounded to the dollar; the cap rate uses the exact figures.

Is it accurate?

It is an estimate, not a quote or a guaranteed return. It is only as good as its inputs:

  • From the MLS listing: price, HOA
  • Our estimates and assumptions: rent, property tax, insurance, vacancy, maintenance, management
  • MLS figures are what the listing reports. We have not verified them.
  • Listings in this MLS do not include property tax, so unless you enter your own figure we use 2.2% of the price a year. Look up the property’s value and taxing units at the Cameron Appraisal District (opens in a new tab); a rental does not get the homestead exemption.
  • If a listing advertises its own cap rate, it may leave out vacancy, management or other costs, which makes it look higher.
  • To confirm it, ask for the current lease or rent roll, last year’s tax bill (Cameron County Tax Assessor-Collector) and your own insurance quote from a Texas-licensed agent; coastal wind and flood coverage can cost much more. For a specific property, Ricardo can ask the listing agent for the lease, the tax bill and what the seller pays for insurance.

What it leaves out

  • The mortgage. Your loan shows up in cash flow and cash-on-cash, not in the cap rate.
  • Big repairs and replacements (roof, A/C, appliances) and savings set aside for them.
  • Utilities, lawn care or pest control, if the owner pays them.
  • Closing costs, leasing fees, income taxes in the U.S. or Mexico, and depreciation.
