Cap Rate Methodology — How NOI-Based Cap Rate Is Calculated | Reaixo

How Reaixo calculates capitalization rate from net operating income — and why it deliberately ignores financing.

Cap rate is one of the simplest metrics in real estate investing to state, and one of the easiest to misuse. This page explains exactly what goes into Reaixo's cap rate calculation and, just as important, what it deliberately leaves out.

The Formula

ℹ️
Cap Rate = Net Operating Income ÷ Property Value × 100
NOI is calculated before any mortgage payment — cap rate measures a property's own operating performance, independent of how it's financed.

What Goes Into NOI

  • Gross rental income — monthly or annual rent, plus any other income (parking, laundry, storage fees).
  • Vacancy allowance — a percentage deducted from gross income to reflect realistic turnover between tenants.
  • Operating expenses — property taxes, insurance, HOA, management, maintenance, a capital expenditure reserve, and owner-paid utilities.
  • Property value — the purchase price or current market value used as the denominator.

Effective income (gross income minus vacancy) minus operating expenses equals NOI. Financing costs — principal and interest — are never subtracted at this stage; that's what the Cash Flow methodology is for.

Why Financing Is Excluded on Purpose

Two identical properties purchased with different down payments or loan terms will show the same cap rate, because cap rate is meant to answer a specific question: how does this property perform on its own, independent of how any particular buyer chooses to finance it? That makes it useful for comparing deals on equal footing — but it means cap rate alone tells you nothing about your actual out-of-pocket return, which is what cash-on-cash return measures instead.

⚠️
A Higher Cap Rate Is Not Automatically a Better Deal
Cap rate does not account for appreciation potential, tax treatment, future rent growth, major upcoming repairs, or your own risk tolerance. A high cap rate can just as easily signal higher risk — a weaker market, an older property, higher turnover — as it can signal genuine value.

What This Methodology Does Not Do

It does not predict future rent growth, appreciation, or resale value, and it does not tell you whether a specific property is "worth it" — that depends on your own goals, financing and risk tolerance alongside this one metric.

Frequently Asked Questions

How does Reaixo calculate cap rate? +

Cap Rate = Net Operating Income (NOI) ÷ Property Value × 100. NOI is effective rental income minus operating expenses, calculated before any mortgage payment — so cap rate reflects a property's operating performance independent of financing.

Why is cap rate calculated before the mortgage payment? +

Excluding financing lets you compare properties bought with different down payments or loan terms on equal footing. Two identical properties financed differently will have the same cap rate but different cash-on-cash returns.

What expenses count toward NOI? +

Property taxes, insurance, HOA dues, property management, maintenance, a capital expenditure reserve, and any owner-paid utilities — subtracted from effective rental income (gross rent plus other income, minus a vacancy allowance).

Is a higher cap rate always better? +

No. Cap rate says nothing about financing, your tax situation, appreciation potential, or risk — a higher cap rate can just as easily reflect higher perceived risk in a weaker market as it can reflect a genuinely better deal.

What is the "implied value at target cap rate" calculation? +

It's a reverse calculation — dividing a given NOI by a target cap rate to see what property value would produce that cap rate. It's a scenario tool, not an appraisal or a claim about market value.
