The US generally places no federal restriction on foreigners buying real estate, but the mechanics differ from both civil-law and other common-law systems, and details vary by state.
Title insurance instead of a notary
Rather than a civil-law notary, US deals use a title company that searches title and issues title insurance, with funds held in escrow. The signed deed is recorded at the county recorder’s office — there is no single national land registry.
FIRPTA on sale
A key tax trap for non-residents: under FIRPTA, when a foreign person sells US real estate, the buyer must generally withhold a percentage of the price for the IRS. Plan for it at purchase.
Financing and local taxes
Mortgages are harder for non-residents, and transfer taxes and property taxes vary widely by state and county.
For foreign buyers
State practice, escrow and FIRPTA reward local guidance. A verified US colleague in the relevant state can structure the purchase and the tax.
