A duplex for sale in Miami is a different animal from a condo. There is no association telling you whether you can rent, no HOA eating the yield, and two to four rent checks instead of one. For an international buyer who wants income property with control over the asset, small multifamily is often the cleaner entry — provided the math and the legal status of the units check out.
Live in one unit, rent the other
The classic play with a duplex is to occupy one unit and let the tenant in the second cover most of the mortgage and taxes — a self-financing residence rather than a pure expense. A two-to-four-unit building (duplex, triplex, fourplex) scales that logic: more doors, more diversified rent, less exposure to a single tenant moving out. For a buyer relocating to Miami it is a way to own and earn at the same time; for a pure investor it is straightforward cash flow.

Underwrite a duplex on its rents, not its romance. Take the two market rents, subtract taxes (roughly 2% of value a year), insurance, maintenance, a vacancy allowance and the mortgage — what's left is the cash flow. A duplex with no HOA and two solid leases often cash-flows where a single condo would not, because the second unit carries the cost. The two risks to price in are insurance, which has risen sharply in Florida, and deferred maintenance on older buildings. Get both inspected and quoted before you commit.
Financing two to four units as a foreigner
A non-resident does not get FHA or other government-backed loans — those need residency. What is available is a foreign national loan: typically 30%–40% down, a slightly higher rate, and documentation your bank or accountant prepares. A two-to-four-unit property still qualifies as residential financing (five units and up flips to commercial terms), so a fourplex is usually the ceiling before the loan changes character. Many buyers pay cash and refinance once they hold the asset and have U.S. rental history.
Where the value is: emerging areas
The established neighborhoods are priced for it; the cash flow tends to live where the area is still turning. Little Havana, Allapattah and Little River hold dense stock of older small multifamily, sit minutes from Brickell and the Health District, and have drawn real investment and rezoning momentum. And a point foreign landlords value: Florida has no rent control — rents reset to the market at renewal, statewide. Buy the location's trajectory, not just today's rent.
