You cannot get a US mortgage for a foreign property. American banks lend against collateral they can seize through US courts, and no US court can foreclose on a house in Mexico, Portugal, or anywhere else. To buy abroad, you will need to use one of five alternative paths: borrow against equity in your US home, work with a multinational bank that operates in both countries, get a mortgage from a local bank in the target country, take out an unsecured personal loan, or finance directly through the developer or seller.
Why American Lenders Won’t Finance Property Abroad
Every conventional US mortgage is backed by a lien on the property itself. Stop paying, and the lender forecloses through the local court system and recovers the debt by selling the home. That mechanism breaks when the property sits in another country. A US court has no authority to seize a condo in Portugal or a villa in Mexico, so the lender has no meaningful collateral.
Appraisal is the second obstacle. Domestic lenders require valuations that conform to the Uniform Standards of Professional Appraisal Practice, which depend on transparent sales records and standardized methodology.1Board of Governors of the Federal Reserve System. Frequently Asked Questions on the Appraisal Regulations and the Interagency Appraisal and Evaluation Guidelines Many foreign markets lack the recorded-sales infrastructure that process assumes. The combination of unenforceable collateral and unverifiable value means no traditional US mortgage product exists for overseas real estate.
Borrowing Against Your US Home
If you already own a home in the United States with substantial equity, you can borrow against it and use the cash abroad. A cash-out refinance replaces your existing mortgage with a larger one and hands you the difference. A home equity line of credit (HELOC) adds a revolving line as a second lien. Either way, the collateral is your US property, so underwriting works like any domestic transaction. For a conventional cash-out refinance on a single-unit primary residence, Fannie Mae caps the loan-to-value ratio at 80 percent.2Fannie Mae. Eligibility Matrix
On the foreign side, this is the simplest route. You arrive as a cash buyer, which most overseas sellers prefer. There is no foreign bank to underwrite you, no cross-border title review, and no currency-denominated payments to track for the next 20 years.
The tax catch surprises many buyers. Interest on a HELOC or home equity loan is deductible only if the borrowed funds are used to buy, build, or substantially improve the home that secures the loan.3Internal Revenue Service. Real Estate Taxes, Mortgage Interest, Points, Other Property Expenses Pull equity from your US home to buy a beach house in Costa Rica, and that interest is not deductible. For a cash-out refinance, the portion of the new loan that exceeds your old balance is treated the same way: deductibility depends on how you spend it. That gap can run to thousands of dollars a year over the life of the loan.
The underlying risk is that you have put your US home on the line for a foreign investment. If the overseas property loses value or rental income disappoints, you still owe the full balance secured by your primary residence. Default means foreclosure at home, not abroad.
Multinational Bank Mortgage
A handful of global banks with branches on both sides of the border can originate a mortgage on the foreign property itself. HSBC is the most prominent, offering overseas mortgage products across Europe, Asia, and the Middle East. Because the bank has legal entities in both countries, it can record a lien with the local land registry in the target country and enforce it under local law.
These products sit inside premier or private banking tiers and come with real asset requirements. HSBC’s Premier tier requires at least $100,000 in combined deposits and investments held with the bank.4HSBC Bank USA. Premier Checking Expect to keep that balance in place for the life of the loan, not just at closing. Down payments for overseas properties typically range from 15 to 50 percent of the purchase price, depending on the country.5HSBC International Services Bank. Getting a Mortgage for an Overseas Property
Approval hinges on whether the bank actually lends in your specific target country. A bank that offers mortgages in France may not offer them in Thailand. If you fall below the asset threshold or the bank does not operate in your market, the door is closed.
One benefit worth factoring in: because the mortgage is secured by the foreign property and that property can qualify as your second home, the interest may be deductible on your US return. The IRS defines a qualified residence as your principal home plus one other residence you select, with no requirement that the second home sit inside the United States.6Office of the Law Revision Counsel. 26 US Code 163 – Interest The home must have sleeping, cooking, and toilet facilities, and your combined acquisition debt across both homes cannot exceed $750,000.7Internal Revenue Service. Publication 936 (2025), Home Mortgage Interest Deduction
Local Bank Mortgage in the Target Country
In many countries, domestic banks will lend directly to non-resident foreign buyers. You apply with a bank in the country where the property sits, and the loan is denominated in the local currency and governed by local law. This is the most common route for Americans buying in established expat markets such as Mexico, Spain, France, and Portugal.
Down payments for foreign buyers run higher than what residents pay, often 30 to 40 percent or more.8HSBC International Services Bank. How to Finance an Overseas Property Interest rates track the local market, not US rates, and documentation requirements vary widely. At minimum, plan to provide proof of identity, income verification through US tax returns and bank statements, and sometimes a local tax identification number. Some countries require you to open a local bank account before the mortgage application can proceed.
Loan payments will be in the local currency, which creates exchange-rate exposure for the entire repayment period. If the dollar weakens against the euro or the peso, your effective monthly payment rises even though the foreign-currency amount stays the same. A 10 or 15 percent swing over a multi-year loan adds up. Rental income earned in the same currency partially offsets the exposure.
Interest on a foreign mortgage that secures a qualifying second residence can be deductible on your US return under the same qualified-residence rules described above.
Unsecured Personal Loan
For lower-priced properties, raw land, or a gap in your cash budget, an unsecured personal loan sidesteps the collateral problem entirely. No property secures the debt, so the lender does not care where the asset sits. Approval depends on your credit profile, income, and existing debt load.
Most major US banks cap unsecured personal loans at $50,000 to $100,000. Wells Fargo lends up to $100,000 with rates starting at 6.74 percent APR for borrowers with excellent credit and autopay, running up to 25.99 percent APR at the higher-risk end.9Wells Fargo. Personal Loan Rates Those rates are substantially higher than a secured mortgage, which is the cost of borrowing without collateral. Repayment terms typically run two to seven years, far shorter than a 30-year mortgage, so monthly payments can be steep relative to the amount borrowed.
This path works best as a bridge rather than full financing. If you have cash for 70 percent of a property and need $40,000 to close, a personal loan handles it without pulling in any foreign bank. Interest on an unsecured loan is not deductible as mortgage interest, because no property secures the debt. If you default, the lender’s recourse is a civil judgment in US court to garnish wages or seize domestic assets; the foreign property is untouched.
Developer or Seller Financing
In many international markets, the seller or developer acts as the lender. This is common with new-construction resort communities in Latin America, Southeast Asia, and parts of Southern Europe, where developers offer in-house financing specifically to attract foreign buyers who cannot easily get bank loans.
Developer financing typically requires a down payment of 20 to 50 percent before or during construction, with the balance paid over a shorter term of five to ten years.8HSBC International Services Bank. How to Finance an Overseas Property Interest rates are set by the developer, not a central bank benchmark. Some developers offer attractive rates as a sales incentive; others charge a premium for the convenience.
Seller carry-back arrangements work similarly but involve an individual owner. The seller takes a down payment and finances the rest through a private contract recorded with the local land registry. The buyer pays the seller directly each month. Default consequences in these arrangements tend to be harsher than what Americans are used to; many foreign jurisdictions allow the seller to reclaim the property through a streamlined forfeiture process without a drawn-out court case.
With developer financing on pre-construction projects, the biggest risk is that your deposit may not be protected if the developer runs out of money. Some countries require buyer payments to go into regulated escrow accounts, released only as construction milestones are verified. Many do not. Before signing, confirm whether local law requires escrow for off-plan purchases, verify the escrow account independently, and never wire money directly to a sales agent or unrelated third party. That is where most buyers who lose money get burned.
Confirm You Can Legally Own First
Before you lock in a financing method, verify that you are legally permitted to own property in the target country. Several popular markets restrict or prohibit foreign ownership outright.
Mexico is the example Americans run into most often. Foreigners cannot directly own residential property within the restricted zone, which covers all land within 50 kilometers of the coast and 100 kilometers of any international border. That zone includes nearly every popular beach town. The workaround is a fideicomiso, a bank trust in which a Mexican bank holds legal title while you, as the beneficiary, retain practical ownership rights to live there, rent, renovate, sell, or pass to heirs. The trust runs for 50 years and can be renewed. Setup costs are folded into closing costs that typically run 5 to 9 percent of the purchase price, with an annual trust fee of roughly $350 to $650.
Other notable rules: Switzerland’s Lex Koller law limits sales of property to foreign nationals and subjects purchases to government approval. Thailand prohibits foreigners from owning land, though condominiums are allowed up to a 49 percent foreign-ownership quota per building. China grants usage rights rather than outright ownership. Singapore requires government approval for foreign buyers of landed residential property. Rules change, so consult a local attorney in the target country before committing funds.
US Tax and Reporting Obligations
Buying property abroad triggers US reporting requirements that catch many owners off guard. Penalties are steep compared with the effort of filing, so these are worth taking seriously.
Foreign Account Reporting
If you hold foreign financial accounts with a combined value exceeding $10,000 at any point during the year, you must file a Report of Foreign Bank and Financial Accounts (FBAR) with FinCEN by April 15, with an automatic extension to October 15.10Internal Revenue Service. Report of Foreign Bank and Financial Accounts (FBAR) Foreign real estate held directly is not itself reportable on the FBAR, but the foreign bank account you open to pay the mortgage, collect rent, or cover utilities almost certainly is.11Internal Revenue Service. Comparison of Form 8938 and FBAR Requirements Civil penalties for non-willful FBAR violations currently exceed $16,000 per report, and willful violations run much higher.
Separately, FATCA requires certain taxpayers to report specified foreign financial assets on Form 8938 with the annual return. For an unmarried taxpayer living in the United States, the threshold is $50,000 in total foreign financial assets at year-end or $75,000 at any point during the year. For married joint filers, those thresholds double. Higher thresholds apply if you live abroad.12Internal Revenue Service. Summary of FATCA Reporting for US Taxpayers Failing to file Form 8938 carries a $10,000 penalty, with an additional $10,000 for every 30-day period the failure continues after IRS notice, capped at an additional $50,000.13eCFR. 26 CFR 1.6038D-8 – Penalties for Failure to Disclose
Rental Income and Foreign Tax Credits
If you rent the foreign property, the income is taxable on your US return regardless of where it was earned. US citizens and resident aliens must report worldwide income.14Internal Revenue Service. Reporting Foreign Income and Filing a Tax Return When Living Abroad You will likely owe local tax to the country where the property sits as well. To avoid double taxation, you can claim a foreign tax credit on Form 1116 for income taxes paid to the foreign government, which reduces your US liability dollar for dollar.15Internal Revenue Service. Foreign Tax Credit You can instead deduct foreign taxes on Schedule A, but the credit is almost always the better deal.
Mortgage Interest Deduction
Deductibility of mortgage interest on a foreign property turns on how the loan is structured. Debt secured by the foreign home itself, when you designate that home as your second residence, qualifies for the mortgage interest deduction under the same rules as any US second home. Debt from a HELOC or cash-out refinance on your US property, used to buy abroad, does not qualify, because the borrowed funds were not used to improve the home securing the loan. An unsecured personal loan carries no mortgage interest deduction at all. The financing method you choose shifts the total cost of ownership by thousands of dollars a year.
Currency Exchange Costs
International property purchases move large sums across currencies, and the spread between what banks charge and the mid-market exchange rate can quietly consume thousands of dollars. Traditional banks apply a markup on foreign exchange that often exceeds one to two percent of the amount converted, on top of any stated wire transfer fee. On a $200,000 purchase, a two percent spread costs $4,000 before you count wire fees on both ends.
Specialist transfer services like Wise typically charge far less, with fees as low as 0.1 percent on large transfers.16Wise. International Money Transfer For a property purchase involving multiple payments across months, choosing the wrong transfer method can add up to tens of thousands in avoidable cost.
Currency risk does not end at closing. An ongoing mortgage denominated in a foreign currency means your effective payment moves with exchange rates every month. Some buyers hold income or savings in the same currency as the mortgage, so the exposure partially cancels. Others lock in forward contracts for large upcoming payments. There is no free hedge, but ignoring the risk is the most expensive choice of all.
