One of Bitcoin holders' biggest frustrations: you have significant wealth in Bitcoin, but traditional mortgage lenders ignore it. Banks lend against W-2 income, property values, and stock portfolios. Bitcoin? Not recognized.
That's changing. A small but growing number of lenders now offer mortgages that explicitly accept Bitcoin as part of the qualification picture — either as collateral for the loan itself, as a source of down payment funds, or as an asset that demonstrates financial strength.
This guide covers exactly how Bitcoin-collateralized mortgages work, which lenders offer them, and when using Bitcoin to buy real estate makes sense versus just selling BTC.
Why Traditional Mortgages Don't Work for Bitcoin Holders
Standard mortgage qualification relies on three things: income (W-2 or business income), credit score, and assets (bank accounts, investment accounts). Bitcoin falls awkwardly into all three:
Income: If you "live off Bitcoin" through loans against your holdings or occasional sales, you may not show consistent W-2 income. Lenders want to see 2 years of tax returns with regular income — Bitcoin income from sales is inconsistent by nature.
Assets: Some lenders will count Bitcoin holdings as assets (like they count brokerage accounts), but many require assets to be in custodial accounts they can verify, stable, and liquid. Bitcoin is liquid, but lenders worry about its volatility — a 50% drop in Bitcoin value could eliminate your apparent financial cushion.
Down payment source: If your down payment comes from selling Bitcoin, lenders see a "large deposit" in your bank account and ask for documentation. Explaining a $200,000 Bitcoin sale to an underwriter who has never seen a Bitcoin transaction can derail a mortgage.
The result: many serious Bitcoin holders have trouble getting mortgages despite holding seven-figure net worth in Bitcoin.
Option 1: Bitcoin-Collateralized Mortgage (Direct)
A Bitcoin-collateralized mortgage uses your Bitcoin directly as loan collateral. The lender holds your Bitcoin in a custody arrangement, and it secures the mortgage loan.
How it works:
- You pledge a specified amount of Bitcoin as collateral
- The lender holds the Bitcoin in a custodial account
- You receive mortgage funds to purchase the property
- The property and your Bitcoin are both collateral for the loan
- As you pay down the mortgage, some Bitcoin is released back to you
- If you default, the lender can sell the Bitcoin and/or foreclose on the property
The key advantage: You keep the Bitcoin's upside. If Bitcoin doubles while you hold the mortgage, you benefit from that appreciation (minus the interest you've paid). You never sold the Bitcoin.
The key risk: If Bitcoin drops significantly, you may face a margin call — required to add more Bitcoin collateral or pay down the mortgage to maintain the required loan-to-value ratio.
Who Offers Bitcoin-Collateralized Mortgages?
Milo — The most established US Bitcoin mortgage lender. Milo offers 30-year mortgages backed by Bitcoin. You pledge Bitcoin as collateral, Milo holds it in custody, and you receive mortgage funds. No income verification required — the Bitcoin collateral is the qualification basis. Available in most US states for investment properties and primary residences.
Key terms (as of 2026):
- Loan-to-value (LTV): typically 100% of property value
- Bitcoin collateral required: 1:1 or more versus loan amount
- Interest rates: higher than conventional mortgages (typically +1–3% above conventional)
- No income verification required
- Available for US residents purchasing US property
Ledn — Canadian company offering Bitcoin-backed mortgages. Primarily serves Canadian markets with expansion to other jurisdictions.
Unchained Capital — While better known for Bitcoin-backed loans (see our guide to borrowing against Bitcoin), Unchained also provides real estate financing solutions for Bitcoin holders.
Note: This space is evolving rapidly. Check current offerings — terms, availability, and lenders change frequently.
Option 2: Use Bitcoin as Down Payment Source (Sell BTC)
The simpler approach: sell some Bitcoin, use the proceeds as your down payment, and get a conventional mortgage.
The process:
- Sell Bitcoin on a major exchange (Coinbase, Kraken, Swan)
- Wait for the funds to settle in your bank account
- Document the sale for the mortgage lender (trade history, exchange statements)
- Use as down payment on a conventional mortgage
Tax implications: Selling Bitcoin is a taxable event. If you've held for over a year, long-term capital gains rates apply (0%, 15%, or 20% depending on income). If held under a year, short-term rates apply (ordinary income, up to 37%).
For a $100,000 down payment from Bitcoin bought at $30,000/coin:
- Sell at $90,000/coin: proceeds = $100,000
- Cost basis: approximately $33,333 (0.333 BTC)
- Long-term gain: ~$66,667
- Tax at 20% rate: ~$13,333
You'd need to sell ~$113,333 in Bitcoin to net $100,000 after tax.
Documentation advice for lenders: Request a full trade history from your exchange before applying. Prepare a letter explaining cryptocurrency (some underwriters are unfamiliar). Use an exchange that produces clean, professional account statements — Coinbase and Kraken produce statements similar to brokerage reports.
Option 3: Cross-Collateralization (Real Estate + Bitcoin Loans)
Some Bitcoin holders use a more sophisticated structure:
- Take a Bitcoin-backed line of credit (through Unchained, Ledn, or similar) using Bitcoin as collateral
- Use that line of credit for a large cash down payment (20–40%)
- Get a conventional mortgage on the remaining balance (with a large down payment, qualification is easier)
- Now you have: conventional mortgage (low rate), Bitcoin line of credit (moderate rate), and you never sold Bitcoin
The advantage: You potentially get better mortgage rates than a pure Bitcoin-collateral mortgage, while still preserving your Bitcoin position.
The risk: You're servicing two loans instead of one. If Bitcoin drops significantly, your line of credit could face a margin call.
Option 4: Bitcoin as Asset Verification for Conventional Mortgages
Some conventional lenders now accept Bitcoin held at regulated exchanges (Coinbase, Fidelity) as a documented asset — similar to how they treat brokerage accounts.
Requirements (typical):
- Bitcoin held at a regulated custodial exchange (not self-custody)
- Exchange account statements showing balance and history
- Often require Bitcoin to be "seasoned" (held for 60+ days, not a recent large deposit)
- Lender must be willing to count volatile assets — not all lenders do
The limitation: Lenders typically only count assets they can verify easily and that are stable. They may apply a haircut to Bitcoin's value (counting it at 50–80% of market value) due to volatility. And many conventional lenders simply don't have policies for Bitcoin — the underwriter doesn't know what to do with it.
Best approach: Work with a mortgage broker who has placed Bitcoin-holding clients before. They know which lenders are Bitcoin-friendly and can navigate the documentation requirements.
Interest Rate Comparison
Bitcoin-collateralized mortgages typically carry a premium over conventional rates:
| Mortgage Type | Typical Rate Premium | Qualification | |--------------|---------------------|---------------| | Conventional 30-year | Baseline | W-2 income, 20% down, good credit | | FHA Loan | -0.25% to baseline | Lower down payment, lower credit | | Jumbo Loan | +0.25–0.5% | Large loan amounts | | Bitcoin-collateralized (Milo) | +1–3% above conventional | Bitcoin collateral, no income verification | | DSCR loan (investment property) | +0.5–1.5% | Property income, no personal income requirement | | Hard money loan | +4–8% | Speed and flexibility, not credit-based |
For many Bitcoin holders, the +1–3% premium on a Bitcoin mortgage is worth paying to avoid selling BTC. Whether it makes sense depends on your view of Bitcoin's future price appreciation relative to the interest cost.
The Math: Sell Bitcoin vs. Bitcoin Mortgage
The key question: is it better to sell Bitcoin for a down payment and get a cheap conventional mortgage, or pledge Bitcoin as collateral and keep it?
Scenario: $500,000 home purchase
Option A: Sell Bitcoin for down payment
- Sell $130,000 Bitcoin (to net $100,000 after ~$30,000 in capital gains tax at 20%)
- Put $100,000 down (20%), get $400,000 conventional mortgage at 6.5%
- Monthly payment: ~$2,528
- Bitcoin sold and gone: can't participate in future Bitcoin appreciation
Option B: Bitcoin-collateralized mortgage (Milo)
- Pledge $500,000 in Bitcoin as collateral
- Get $500,000 mortgage at 9.5% (Bitcoin mortgage rate premium)
- Monthly payment: ~$4,207
- Bitcoin retained: participates in full future appreciation
- Difference in monthly payment: $1,679/month = $20,148/year
Break-even question: Does retaining $130,000 in Bitcoin generate more than $20,148/year in returns? At $130,000, that requires a 15.5% annual return just to break even on the higher rate. Bitcoin's historical CAGR is well above that, but past performance is not guaranteed.
The honest answer: If you expect Bitcoin to significantly outperform the spread, retain the Bitcoin. If you want simplicity and lower debt service, sell and take the conventional mortgage.
Risks Specific to Bitcoin Mortgages
Margin calls: If Bitcoin drops significantly, your lender may require additional collateral or partial loan repayment. If Bitcoin drops 50%, what was a 100% LTV mortgage might now require you to post more Bitcoin or pay down the principal.
Custody risk: Your pledged Bitcoin is held by the lender. You need to trust their custody practices, security, and financial stability. If the lender fails (as some crypto lenders did in 2022–2023), your collateral is at risk.
Rate risk: Bitcoin mortgages have higher interest rates. If conventional rates drop significantly, you're locked into a higher rate while conventional borrowers refinance. Some Bitcoin mortgage products have prepayment penalties.
Tax complexity: Bitcoin used as mortgage collateral creates documentation requirements. Work with a CPA familiar with cryptocurrency to ensure you're tracking basis correctly, especially if your pledged Bitcoin has been used in multiple financing arrangements.
When a Bitcoin Mortgage Makes the Most Sense
You have substantial Bitcoin but limited liquid income. If you're a Bitcoin-wealthy, income-poor individual (self-custody holders with appreciation but limited W-2 income), a Bitcoin mortgage may be your only practical path to real estate.
You have strong conviction Bitcoin will significantly appreciate. The premium rate only makes economic sense if Bitcoin's appreciation exceeds the rate spread over the mortgage term.
You're buying an investment property. For investment properties, the qualifying income can come from rental income (DSCR loans). Pairing a Bitcoin asset base with rental income qualification might avoid the Bitcoin mortgage rate premium.
You need to buy quickly. Some Bitcoin mortgage products (especially Milo) offer faster closing than conventional mortgages, which require extensive income verification.
Practical Steps to Get a Bitcoin Mortgage
-
Assess your Bitcoin position — How much Bitcoin do you have? What's the current value? What would you pledge as collateral? Don't pledge Bitcoin you can't afford to lose if the price drops and a margin call occurs.
-
Contact Bitcoin-aware lenders — Start with Milo (for US purchases). Get a pre-qualification to understand terms.
-
Consult a Bitcoin-literate CPA — Understand the tax implications before proceeding. If this involves selling Bitcoin for a down payment, calculate the tax cost. If pledging Bitcoin, understand the margin call scenarios.
-
Compare with conventional options — Get a conventional mortgage pre-approval simultaneously. Compare rates and terms directly.
-
Consult an estate attorney — If you're using significant Bitcoin as collateral, ensure your estate plan accounts for this. The pledged Bitcoin cannot be in cold storage if it's being held by a lender.
-
Decide based on your Bitcoin conviction — This ultimately comes down to how strongly you believe in Bitcoin's future appreciation. The math is not magic — you're paying more now in hopes that Bitcoin appreciation exceeds the premium.
Frequently Asked Questions
Can I use self-custody Bitcoin as mortgage collateral? No. Bitcoin in cold storage (hardware wallets, self-custody) cannot be directly pledged as collateral because the lender needs to hold or verify custody. You'd need to transfer the Bitcoin to a custodian the lender approves (or the lender's custody platform) as part of the loan arrangement. This means self-custody Bitcoin becomes custodial Bitcoin for the duration of the mortgage. Verify your lender's custody provider's financial stability carefully.
What happens to my pledged Bitcoin if the lender goes bankrupt? This is the key risk. Review the lender's terms of service carefully regarding what happens in insolvency. Reputable lenders use segregated custody (your Bitcoin is titled in your name, held in custody on your behalf), which means you're a secured creditor if they fail. However, as we saw in 2022 with Celsius and BlockFi, "reputable" doesn't mean safe. Only pledge Bitcoin with lenders whose custody structure and financial health you're comfortable with.
Does pledging Bitcoin as collateral trigger capital gains tax? No. Pledging Bitcoin as collateral is not a sale. You don't realize a gain when you pledge your Bitcoin to a lender — you realize a gain only if the lender sells it (in a liquidation scenario) or if you sell it to pay off the loan. The IRS has not explicitly ruled on this for all scenarios, but the consensus treatment is that collateralization is not a taxable event.
Can I use Bitcoin held in an IRA as mortgage collateral? No. IRA-held assets cannot be used as personal collateral — doing so would be a prohibited transaction that disqualifies the IRA, triggering immediate tax and penalties on the entire balance. Bitcoin in a self-directed IRA must remain inside the IRA structure.
What credit score do I need for a Bitcoin mortgage? It varies by lender. Some Bitcoin mortgage products (like Milo's crypto-backed mortgage) don't require traditional income verification, so they may have more flexible credit requirements than conventional mortgages. However, better credit still means better rates. Check directly with the lender for their specific requirements.
Should I pay down my Bitcoin mortgage early if Bitcoin appreciates a lot? Maybe. If Bitcoin appreciates significantly, your loan-to-value ratio improves (you owe the same on the mortgage but your collateral is worth more). Some lenders will release excess collateral if your LTV drops below a certain threshold. Paying down the mortgage faster frees up the pledged Bitcoin but costs you capital. It depends on your cash flow, rate, and view of Bitcoin's continued appreciation.
Is this available outside the US? Some providers serve international markets (Ledn serves Canada and has other international offerings). The availability of Bitcoin-collateralized mortgages varies significantly by country due to different regulatory environments. The category is growing globally but US-focused options are most developed as of 2026.
