Miami Property for International Buyers: Condos, Taxes and Climate Risk

Miami has been an international property market for longer than most American cities. Buyers from Latin America have used it as a safe place for capital and a second home for decades; Europeans buy for the climate and the beaches; and an influx of Americans from high-tax states has added a new layer of demand. The result is a deep, liquid market with a large supply of condominiums. For foreign buyers, the attractions are clear, but so are a set of US tax rules and Florida-specific risks that need careful planning.

The shape of the market

Miami's housing splits into two very different products.

Condominiums. High-rise apartment towers dominate the skyline in Brickell, Downtown, Edgewater, Sunny Isles Beach, Miami Beach and along Biscayne Bay. Condos offer views, amenities and easy lock-up-and-leave ownership, which suits international buyers. Many new towers are sold pre-construction with deposits paid in stages.

Single-family homes. Houses in Coral Gables, Coconut Grove, Pinecrest, Key Biscayne and Miami Beach's residential islands are scarcer and appeal to families relocating permanently. Waterfront houses with private docks sit at the top of the market.

The two products behave differently. Condo prices depend heavily on new supply and on building condition; house prices depend on scarcity and school districts.

Florida taxes

Florida has no state income tax, a key attraction for Americans moving from other states. For international buyers, the more relevant taxes are:

• Property tax, charged by the county and local authorities on assessed value. Florida's homestead exemption and the Save Our Homes cap on annual assessment increases apply only to a permanent residence of a qualifying owner, so most foreign second-home owners pay without these protections. Non-homestead properties have a separate, higher cap on assessment increases.
• Documentary stamp tax on deeds and on mortgages at the time of purchase.
• Tourist taxes on short-term rentals, collected by the host or platform.

Federal taxes for foreign owners

Rental income. Rent paid to foreign owners is subject to US withholding on the gross amount unless the owner elects to be taxed on net income by filing a US return, which allows deductions for expenses, depreciation and mortgage interest.

FIRPTA on sale. When a foreign person sells US property, the buyer generally must withhold a percentage of the gross sale price and send it to the IRS. The seller files a return to settle the actual tax and recover any excess. Planning for FIRPTA affects cash flow on sale.

Estate tax. Non-resident foreign owners of US property are subject to US federal estate tax on their US assets, with a far smaller exemption than US citizens and residents receive. A Miami home held directly can create a large estate tax bill for heirs. Estate tax treaties with some countries, and structures such as companies or trusts, can change the outcome, but each has costs and trade-offs. This is the single most important area for advice before buying.

Condo safety rules

After the 2021 collapse of Champlain Towers South in Surfside, Florida passed laws requiring milestone structural inspections for older condominium buildings and structural integrity reserve studies, with owners' associations required to fund reserves for key structural components rather than waive them.

The effect has been significant. Many older buildings have faced special assessments for repairs and higher monthly fees as reserves are built up. When buying a condo, ask for:

• the building's milestone inspection report and reserve study
• the association's budget and reserve balance
• any planned or approved special assessments
• the association's insurance cover and litigation history

Insurance and climate risk

Miami is exposed to hurricanes, storm surge and flooding, and insurance costs in Florida have risen sharply. Homeowners and condo associations face higher premiums, and some private insurers have left the market. Flood insurance is usually separate from standard cover and is required by lenders in designated flood zones.

Before buying, check the property's flood zone, elevation, windstorm protection (impact windows and doors, roof condition) and an insurance quote. In some cases, insurance and association fees change the economics of a purchase as much as the price.

Restrictions on certain buyers

Florida has restricted property purchases by certain nationals of countries it designates as countries of concern, particularly near military installations and critical infrastructure, with stricter rules for some nationalities. Most international buyers are unaffected, but buyers from the listed countries should take legal advice.

Financing

Foreign buyers can obtain US mortgages, often through lenders that specialise in foreign national loans. Expect larger deposits, higher rates than for US residents and more documentation. Many international buyers pay cash. Pre-construction condos typically require staged deposits, which should be held in escrow under Florida law.

How a purchase works

US purchases run differently from those in many other countries. Buyers usually work with a licensed real estate agent and a Florida real estate lawyer or a title company. After an offer is accepted, the buyer pays an earnest money deposit into escrow and has an inspection period to commission surveys, review condo documents and, if needed, secure financing. A title company searches the public records and issues title insurance, which protects against defects in the seller's title. At closing, the deed is signed and recorded with the county.

Foreign buyers who will receive rent or eventually sell will need a US taxpayer identification number, usually an ITIN, to file returns. Applying early avoids delays later. Many buyers also open a US bank account to pay property taxes, association fees and insurance.

What moves Miami prices

Driver	Effect
Domestic migration	Movers from other US states support demand
Latin American conditions	Political and currency instability abroad sends capital to Miami
US dollar	A strong dollar makes Miami more expensive for foreign buyers
Condo supply	Waves of new towers can soften prices for older stock
Insurance and fees	Rising costs weigh on older condos and affordability
Interest rates	Affect local and mortgaged buyers more than cash buyers

Scenarios

Divergence. Newer condos and well-located houses hold value while older condo buildings with large assessments lag, widening the gap between the two.

Steady international demand. Instability elsewhere and a long-standing role as a gateway city keep foreign buyers coming, particularly for new towers and waterfront houses.

Cost squeeze. Insurance, fees and climate risk become the dominant story, slowing demand from buyers who focus on running costs.

Practical points

• Take US estate tax advice before choosing how to hold the property.
• Check flood zone, elevation and insurance costs before making an offer.
• For condos, read the inspection report, reserve study and association finances.
• Plan for FIRPTA withholding when you eventually sell.
• Use a Florida real estate lawyer and title insurance, standard in US purchases.

Miami rewards buyers who treat it as a long-term base rather than a quick trade, and who budget for the true cost of owning in a subtropical, hurricane-exposed city.
