BTC Loans for Real Estate: What Actually Works

A developer in Austin reached out last year with a specific problem. He had 3 BTC — bought at $42,000 over two years — and a $300,000 down payment needed in 60 days for a house in Round Rock. Selling meant a $189,000 capital gains bill. Borrowing against the BTC at quote-only APR meant $3,000/month in interest on a $210,000 loan. He chose the loan. For the full tax analysis behind this type of decision, see our guide on borrowing versus selling.

This is the scenario that drives real estate BTC loan searches. Not "should I borrow against crypto" — but "I know I can borrow, but will it actually work for a $400K property purchase?" That answer requires specifics: LTV math, mortgage lender requirements, tax treatment, and platform selection. Here is the complete picture.

The core math: How much can you borrow for a property?

Most BTC lending platforms max out at 50% LTV. Some offer higher — Figure offers 50% LTV on certain structures — but higher LTV means more liquidation risk and typically higher rates. For a conservative real estate strategy, plan around 50% LTV. Our LTV & liquidation guide covers the full mechanics.

Working backward from a $300,000 down payment need: at 50% LTV, you need $600,000 in BTC collateral. At a $100,000/BTC reference price, that is roughly 6 BTC. With reviewed lender APR examples, the annual interest on a $300,000 loan can run into the low-to-mid five figures before fees. Use the calculator with your own BTC price and the reviewed lender inputs you are actually eligible for.

For a $500,000 property with 20% down ($100,000), you need $200,000 in BTC collateral at 50% LTV. The BTC amount and monthly interest estimate should be recalculated from your BTC/USD input and the lender terms you are actually eligible for.

The mortgage lender problem nobody talks about

Here is where most BTC real estate borrowers hit a wall: your mortgage lender does not care that your BTC is not sold. From their perspective, you are borrowing $200,000 to make a down payment. That is a debt obligation that affects your debt-to-income ratio.

Conventional conforming loans cap DTI at 43% front-end, 50% back-end. If your BTC loan payments are $1,100/month, that counts against your DTI the same as any other loan. A borrower with $10,000/month gross income and $1,100 in existing obligations has $8,900 of capacity. Adding a $1,100/month BTC loan payment leaves $7,800 for a mortgage. The supported mortgage amount depends on the mortgage rate, taxes, insurance, and lender underwriting at the time you apply. For borrowers already near their DTI ceiling, the BTC loan payment can push them over the threshold and disqualify them from the mortgage.

The workaround: Some borrowers close the BTC loan before the mortgage application, pay it off with the mortgage proceeds or income, and keep the BTC. Others structure the BTC loan as a bridge loan — short-term financing that is replaced by the mortgage — which some lenders will accept if the bridge is documented correctly. Portfolio lenders and DSCR (debt service coverage ratio) lenders are more flexible with non-traditional income and debt structures.

The tax calculation that drives the decision

For someone holding BTC with significant appreciation, the tax case for borrowing over selling is straightforward. On a $300,000 capital gain at a 37% marginal rate (federal + state blended), selling triggers roughly $111,000 in taxes owed in the year of sale. Borrowing instead: zero capital gains event. The interest cost is deductible if the loan is used for investment purposes — and buying a primary residence does not qualify, but a rental property or business property does. Consult a CPA before assuming deductions.

The break-even math: a BTC loan at quote-only APR costs $36,000/year on $300,000. That exceeds the first-year capital gains tax of roughly $20,000 on a smaller gain — but on a $600,000 gain (selling 5.7 BTC at $105,000 vs $0 cost basis), the $111,000 tax bill dwarfs the $36,000/year interest cost. The larger the unrealized gain, the stronger the borrowing case.

Which platform for a real estate use case?

For real estate-backed BTC loans, two factors matter most: loan size and custody model. A $100,000–$300,000 loan for a down payment sits squarely in Ledn's sweet spot (retail-friendly, competitive rates, Open Book reporting). For $500,000+, Arch Lending's institutional desk handles custom structures that conventional platforms cannot — including bridge loan terms and open credit lines.

If the BTC is your primary collateral and you want stronger borrower-side control: Unchained's multi-sig vault is designed so the platform does not hold unilateral control of your BTC. For a real estate transaction where you need that collateral intact for the next 60 days, that custody structure may be worth the quote-only APR.

When it does not work

BTC-backed real estate loans break down in three scenarios. First: when BTC is already at 80%+ of your liquid net worth and a 20–30% drawdown would push you below the minimum LTV threshold — a drop that would trigger a margin call and force a sale at the worst moment. Second: when your DTI is already at or near conforming loan limits, making the additional payment a disqualifying factor. Third: when you need the loan for longer than 12–24 months, at which point cumulative interest costs may exceed the tax savings.

The strategy works best for borrowers who have significant unrealized BTC gains, need short-to-medium-term liquidity, have income sufficient to service both the BTC loan and the mortgage comfortably, and are purchasing income-producing or appreciating property where the tax cost of selling would be substantial.
