Greek Mortgage or US Home Equity: Which Route Fits?

Start with who will lend against what

A US conforming lender cannot take a Greek home as security: Fannie Mae's Selling Guide limits eligible property to the United States and its territories. That leaves two real routes. A Greek bank lends against the Greek property. Eurobank publishes up to 65% of commercial value for borrowers who are not Greek or Cypriot citizens, with a floating-rate term of up to 15 years, and Alpha Bank lists up to 70% and up to 20 years for borrowers living permanently outside the EU. Or a US lender lends against your US home and you buy the Greek property with cash.

The decision is rarely either-or. The Greek ceiling usually leaves a gap, and equity can fill it. The choice is how big that gap should be.

Which currency carries the risk

With a euro mortgage, the asset and the debt are both in euros, and your risk is the dollar cost of the payment. With dollar equity, the debt and your income are both in dollars, and your risk sits in the day you convert and in what the euro asset is worth in dollars later.

The scale of that conversion risk is not theoretical. On ECB reference rates, a dollar bought about 13% more euros at the end of 2024 (1.0389 dollars per euro) than at the end of 2025 (1.1750), and the rate was 1.1206 on 9 October 2026. Two buyers with the same equity and the same property, converting a year apart, ended up with very different amounts to spend.

What the tax treatment adds

IRS guidance says home equity loan interest is generally deductible only when the money is used to buy, build or substantially improve the home that secures the loan, and its example of a home equity loan used to buy a vacation home is one that does not qualify. Equity interest on a Greek purchase should therefore be planned as not deductible.

A loan secured on the Greek home and used to buy it is a different animal. IRS Publication 936 treats a second home as a qualified home within a $750,000 combined limit, and does not say the home has to be in the United States. Whether you can itemize, and whether rental use changes the answer, is a question for your tax adviser, but the comparison should start there.

What each route puts at risk

A home equity line or cash-out refinance is secured by the house you live in. If costs, rental income or the dollar move against you, the lender's remedy is against that house. A Greek mortgage is secured by a registered lien on Greek property. Alpha Bank says the lien usually amounts to 120% of the loan and may be registered on the financed property or on another property of sufficient value, so ask each Greek lender exactly which property is being pledged.

Speed and certainty

Neither route guarantees funds by a date. The Greek bank needs your documents, its own valuation and the property's legal papers; one major bank says its pre-approval lasts 120 days. The US lender needs an appraisal and underwriting, and for a principal residence a three-business-day right of cancellation must run out before it may disburse. A seller who wants a fixed deed date may favor the buyer whose funds are already in hand, whereas a buyer still looking can let the Greek loan take its time. The mechanics are in our guide to using US home equity to buy in Greece.

A way to choose

• Lean toward the Greek mortgage if you do not want your US home pledged, your income can carry a payment on a 15-year or 20-year schedule at an exchange rate 10% weaker for the dollar than today's, and the property is straightforward for a bank to value and document.
• Lean toward US equity if the property or island is one a Greek bank may value conservatively or decline, if you have a low-rate first mortgage you do not want to touch and a line available behind it, or if a certain completion date matters more than the interest rate.
• Blend the two if the Greek ceiling leaves a gap smaller than the equity you are comfortable pledging, and plan to repay the US line first.

No route removes the US reporting that comes with a Greek bank account. Once foreign accounts together pass $10,000 at any time in the year, the FBAR applies, whichever route paid for the property.
