Most listings quote a gross yield: a year of rent divided by the asking price. It is a useful first filter, but it is not what you keep.
What comes off the top - Vacancy: even good long-term rentals sit empty between tenants. - Management: local managers usually charge 8–25% of collected rent. - Maintenance, insurance, property tax and condo fees.
What is left is the net operating income. Divide it by the price and you get the net yield before tax.
Then the taxes The country where the property sits usually taxes the rent first. As a US taxpayer, you then report the same rent on Schedule E. The Foreign Tax Credit usually prevents paying twice on the same dollar, but not always in full — and most states give no credit at all.
A worked example A $250,000 apartment advertised at 7% brings in $17,500 a year. After about $5,000 of costs and roughly $2,500 of combined taxes, you keep around $10,000 — about 4%.
