Return measures

Gross yield, cap rate and cash-on-cash return are not substitutes

Which return measure belongs at each stage of a rental-property decision?

A rental market can show an attractive rent-to-value relationship before anyone has measured the expenses, debt or cash required for a property. That makes gross yield useful—but only as the first filter.

RentMarker currently starts with 696 metros that have the required Zillow and employment inputs. After a positive-employment rule, 360 remain. Their median gross yield is 5.8%. Those figures answer a broad market question: where does annualized asking rent sit high relative to typical home value? They do not answer what an owner keeps.

Gross yield earns a place on the shortlist. It does not earn the right to finish the underwriting.
Return stack

Each measure answers a later, narrower question

Moving downward requires more property-specific evidence.

Gross yield is the only layer RentMarker can compute from broad market rent and value alone. The other layers require a real property and explicit operating or financing inputs.

The fast screen

Gross yield compares market rent with market value

The numerator is one year of rent. The denominator is the home value or acquisition price. At market level, RentMarker uses current Zillow ZORI and ZHVI and checks that monthly rent multiplied by twelve, divided by value, reproduces the displayed ratio. This is deliberately simple. It is fast enough to compare hundreds of metros with one definition.

That simplicity also defines the boundary. Gross yield has no property tax, insurance, repairs, vacancy, utilities paid by the owner, management, association dues or capital expenditure. It has no mortgage rate, down payment or closing cost. A market with a high ratio may still contain poor deals once those missing obligations are attached to a specific property.

02
The operating property

Cap rate begins only after net operating income exists

Cap rate replaces broad annual rent with net operating income. The calculation needs a property’s effective rental income and recurring operating expenses before financing. It therefore belongs after a buyer has a plausible unit rent, tax bill, insurance quote, vacancy allowance, management choice and maintenance or reserve policy.

Debt service is normally excluded from net operating income. That is why cap rate can compare the operating economics of two properties without letting different loan structures dominate the result. It is still not a complete return forecast: major rehabilitation, future resale value, income tax and an investor’s required return sit outside the basic measure.

RentMarker does not backfill those missing property inputs with a national percentage. Insurance and taxes vary too much by location and property; repairs and management depend on the asset and operating plan. The honest market-level cap rate is therefore “n/a,” not gross yield with a new label.

The financed deal

Cash-on-cash return changes when the capital stack changes

Cash-on-cash return compares annual pre-tax cash flow with the cash actually invested. It adds the mortgage payment and cash-to-close decision to the property operations already needed for cap rate. Two buyers can purchase the same property at the same price and have the same cap rate while recording different cash-on-cash returns because their down payments, interest rates, points or rehabilitation budgets differ.

Leverage can raise the ratio when the property return comfortably exceeds the cost of debt. It can also amplify a thin margin and turn a small operating miss into negative cash flow. That is why the financing measure belongs last in the stack, after the rent and recurring costs can withstand a downside case.

Decision sequence

Use all three without asking one to do another’s job

  1. 1
    Screen markets with gross yield.

    Use one definition to shrink the search, then inspect jobs, supply, migration and risk.

  2. 2
    Model property operations with cap rate.

    Replace market rent and value with unit evidence, actual price and explicit expenses.

  3. 3
    Test financing with cash-on-cash return.

    Add debt service and every dollar required to acquire and stabilize the deal.

Move from a market ratio to a property stress test.

Use the research screen to find candidates, then enter an actual price, rent and operating assumptions. The tool keeps measured market defaults separate from your property inputs.
