Frequently asked questions
What counts as operating expenses?
Property management, maintenance reserves, insurance, property tax, and HOA fees — but not the mortgage payment itself, which is calculated separately.
What's a good cap rate?
It varies by market, but many investors look for 5–10% depending on location, property class, and risk tolerance.
What is cash-on-cash return?
It measures annual pre-tax cash flow against the actual cash you invested (down payment plus closing costs), showing return on your out-of-pocket investment.
