Crypto-backed loans to buy property abroad: collateral, margin calls and who lends

In brief

A crypto-backed loan lets you pledge coins as collateral and receive fiat money without selling, which can keep your exposure and, in some tax systems, delay a taxable sale. The price is a loan with an interest rate (lender pages quote about 7-9%) and a margin call: if your collateral falls far enough, you must add more or repay part, or the lender sells it. Regulated Swiss banks lend against bitcoin and ether for general liquidity, but we found no lender in the UAE, Cyprus, Portugal, Spain or Georgia that offers crypto-backed property finance. Status as of 6 November 2026, from search summaries; no official page was opened.

Why people consider it

The logic is simple. If you sell coins to buy a flat, you may realise a gain and owe tax, and you give up the exposure you wanted to keep. If you borrow against the coins instead, you receive cash from a lender, buy the property with fiat money and keep the coins as collateral. The loan is repaid later from income, from a sale or from the coins themselves.

The same logic has a flip side. You now have debt on one side and a volatile asset on the other, and the asset that secures the loan can fall just when the property price does not help you. Treat the loan as a leveraged position in crypto, not as a free way to buy a flat.

Who lends

There are four groups, and they are not interchangeable.

• Regulated banks with lombard loans. In Switzerland, Luzerner Kantonalbank and Sygnum (a bank supervised by FINMA) offer lombard loans against bitcoin and ether, and Sygnum accepts other coins too. The money is paid in fiat currencies such as CHF, EUR or USD. Intermediary apps that offer access, such as Relai, say clients must be qualified private investors under the Swiss Financial Services Act. Volatile assets get a conservative loan-to-value ratio. One intermediary, Mt Pelerin, states that it excludes US and Russian persons; that is that intermediary's own rule, not a Swiss law.
• Specialist crypto-mortgage lenders. The ones we found are US products. Lender blogs quote published rates from about 8.25% with collateral close to 100% of the property value, or a pledge of about 1x the property value at 7-9%. A separate US channel pairs a normal mortgage with a crypto-collateralised down-payment loan, which Fannie Mae accepted in March 2026 with reported collateral coverage of 250%. We mention these only to show how the mechanics work; they do not lend against property in your country.
• Crypto lending platforms, centralised and decentralised. Terms are set by the platform or by a smart contract. The lender risk is part of your risk: you hand over collateral to a counterparty. A lender page claiming that its structure avoids margin calls is marketing and should be read in the contract.
• Private lenders and brokers. Terms are negotiated and vary; check who actually holds the collateral and who the legal lender is.

LTV, margin calls and liquidation

Loan-to-value (LTV) is the loan divided by the collateral value. If the loan is 50% of the collateral and the collateral falls by a third, LTV rises to 75%. Lenders define two levels: a margin-call level, at which you must act, and a liquidation level, at which the lender sells.

One guide says lenders typically give 24 to 72 hours to post more collateral or repay part of the loan. A Milo product described in the search results needs a pledge of twice the loan amount and triggers a margin call at 67% LTV. These are examples from lender pages with a commercial interest, not market rules. Read your contract for: the exact levels, the cure period, who sets the price used (one exchange or an index), what happens in a fast market move, and whether interest is paid in cash or added to the loan.

How banks and notaries see the money

Loan proceeds arrive as a normal bank transfer from a regulated lender, which gives the purchase a cleaner paper trail than a chain of conversions. But the buyer still has to explain where the collateral came from. A bank or notary will ask for the loan agreement, proof of the pledge and evidence of the original source of the coins (see the checklist article on proving crypto income). A purchase abroad also triggers the usual source-of-funds checks described in our article on source of funds and taxes.

For mortgages in the country of the property, a local bank will usually assess income and a fiat deposit; a crypto-collateralised personal loan is the buyer's own financing, not a mortgage on the flat. One Swiss forum post reports that a Swiss bank does not treat property abroad as security. That is anecdotal and not a rule, but it is a reason to ask early whether a lombard loan can be used as a deposit and what the bank needs to see.

Country specifics

• Switzerland. Regulated banks lend against bitcoin and ether, with fiat paid out; eligibility is limited by client type and, at some intermediaries, by nationality rules.
• UAE, Cyprus, Portugal, Spain, Georgia. We found no lender in these countries offering crypto-backed property finance. Local banks lend on income and a fiat deposit. See the country articles on buying with crypto for how the deal runs in each.
• United States. Specialist products exist but are for US property and US borrowers.

Taxes

Borrowing may not be a sale in some systems, but a liquidation is a sale in most. We found no official guidance from Germany, Portugal or Spain on borrowing against crypto, and sources about Portugal disagree. One reported case shows the risk: the Spanish tax agency treated a DeFi crypto-backed loan as a taxable event and issued a back-tax bill of about 9 million euro; experts criticised the reading, and it is a single reported case, not a published rule. The question of whether interest is deductible is also open. Ask a tax adviser in your country before you sign, and keep the loan agreement and every liquidation record for the return.

A worked example (illustrative)

Assumptions, all invented for the example: a flat costs 200,000 euro; you pledge coins worth 400,000 euro (2x the loan, which is 50% LTV at the start); interest is 8% a year; the margin call is at 67% LTV and liquidation at 80% LTV.

• Margin call. The collateral can fall from 400,000 to about 298,500 euro (a drop of about 25%) before the margin call.
• Liquidation. At 250,000 euro (a drop of 37.5%) the lender sells.
• Interest. 8% on 200,000 euro is 16,000 euro a year. If the flat earns 4% net, that is 8,000 euro, so you carry a gap of 8,000 euro a year from other money.
• A 30% fall in the coins in 12 months. Collateral drops to 280,000 euro and LTV to about 71%: a margin call. To restore 50% LTV you must add 120,000 euro of collateral or repay 60,000 euro of the loan, within the lender's cure period, perhaps after a fall that is also hurting your other holdings.

The example shows why leverage on a volatile asset needs a large buffer and extra cash outside the pledge.

Failure scenarios

• Off-plan purchase. The loan is drawn and interest accrues while the building is built. A price drop before handover triggers a margin call while you still have stage payments to make and nothing to rent.
• Forced sale at the bottom. A liquidation sells coins at the worst time and may create a tax bill on top of the loss.
• Lender failure. Collateral is held by a counterparty. Check who holds it, in which jurisdiction, and what happens if the lender becomes insolvent.
• Currency mismatch. A loan in one currency and a property in another adds exchange-rate risk.
• Account closure. A lender or bank may close your account or refuse a transfer after additional screening; plan for delays on the purchase date.
• Compliance screening. Lenders and platforms screen holders of Russian, Belarusian, Kazakh and Ukrainian passports to different degrees. The checks are about who you are and where the collateral came from, and a refusal at this stage can be expensive if you have paid a deposit.

Alternatives

• Sell part of the coins and keep the rest, accepting a tax bill but no margin call.
• Convert in stages over several months to reduce timing risk.
• Use an ordinary mortgage in the country where you are resident, based on income, and keep the coins unpledged.
• Choose a smaller property that you can pay for from the proceeds of a sale.
• Wait for a better price or a lower rate. For leverage in general see our article on mortgage leverage and property returns.

Questions to ask a lender

• Who is the legal lender and who holds the collateral?
• What are the margin-call and liquidation levels, the cure period and the price source?
• What is the rate, is it fixed, and how is interest paid?
• Can I repay early, and are there fees?
• Does the lender accept clients with my passport and tax residence?
• What documents do you need to prove the source of the collateral?
• What does the loan agreement say about a lender insolvency?

FAQ

Can I buy a flat abroad with a loan secured on bitcoin? In principle yes, if a lender will lend against your coins and you use the cash to buy. Regulated Swiss banks lend against bitcoin and ether for general liquidity, but we did not find a lender in the UAE, Cyprus, Portugal, Spain or Georgia offering crypto-backed property finance.

What is a margin call? A demand to add collateral or repay part of the loan when the value of the collateral falls and your loan-to-value ratio rises above the lender's limit. One guide says the usual window is 24 to 72 hours; if you do not act, the lender can sell your coins.

Is borrowing against crypto taxable? It depends on the country. Borrowing may not be a sale in some systems, but a liquidation is a sale in most. The Spanish tax agency was reported to have treated one DeFi loan as taxable, so ask an adviser before you borrow.

Will a bank or notary accept money from such a loan? Loan proceeds arrive as a normal bank transfer, which helps. The buyer still has to show the loan agreement, the pledge and where the collateral came from.

Can Russian, Belarusian, Kazakh or Ukrainian passport holders get such loans? Lenders screen applicants differently. One intermediary states that it excludes US and Russian persons; others have their own rules. Check the terms and eligibility before you commit any deposit.
