How to read the results

Each measure answers a different question. Gross yield tells you whether a property is worth a closer look. Cap rate tells you how the property performs on its own. Cash flow and cash-on-cash tell you how it performs with your financing.

The default figures are illustrative assumptions, not recommendations. Replace the vacancy, management, repairs and financing inputs with your own, and confirm taxes with the appraisal district and insurance with a quote for the specific property.

To compare the current portfolio side by side, open any property from the portfolio and choose Run the numbers.

Gross yield
Gross annual rent divided by the purchase price, before any vacancy or expense. It is the quickest screen, and the figure shown on every portfolio card.
Net operating income (NOI)
Rent actually collected, after the vacancy allowance, minus operating costs: taxes, insurance, management, repairs and reserves, and any HOA or owner-paid utilities. Debt payments are not operating costs.
Cap rate
NOI divided by the purchase price. It compares properties as if each were bought for cash, so financing does not distort the comparison.
Cash flow
NOI minus annual debt service (principal and interest). This is what the property pays you after it pays its costs and its loan.
Cash-on-cash return
Annual cash flow divided by the cash you put in: the down payment plus closing costs. It measures the return on your own capital in the first year.
Debt service coverage
NOI divided by annual debt service. Lenders on investment property look at this ratio, and a figure above 1.0 means the property's income covers its loan payments.
