What is a bridge loan?
A bridge loan is a short-term financing solution designed to help homeowners purchase a new property before they have completed the sale of their existing home. These loans "bridge" the gap between two real estate transactions, giving buyers the capital they need to move forward without waiting for their current home to sell.
Bridge loans are secured against the equity in your current home. When your current home eventually sells, the proceeds are used to repay the bridge loan in full. The remaining equity — after paying off both your original mortgage and the bridge loan — becomes cash in your pocket.
Most bridge loans are structured as interest-only loans, meaning you only pay interest during the loan term and repay the full principal when the loan matures (typically when your home sells). This keeps monthly payments lower than a traditional amortizing loan of the same size.
Bridge loans are a popular tool among homeowners in competitive real estate markets where timing is critical. Being able to make a firm offer on a new home — without a home sale contingency — can make your offer significantly more attractive to sellers. In hot markets, this advantage can be the difference between winning and losing a bidding situation.
That said, bridge loans come with higher interest rates than conventional mortgages, typically running 2 to 5 percentage points higher. They also carry closing costs, origination fees, and the inherent risk that your current home may take longer than expected to sell. This calculator helps you understand the full cost picture so you can make an informed decision.
How bridge loan interest is calculated
Bridge loans use simple interest calculated on the outstanding principal balance. Since they are interest-only, the principal does not amortize — every payment goes entirely toward interest, and the full loan amount is due when the term ends.
**Monthly Interest Payment Formula:** \`\`\` Monthly Payment = (Loan Amount × Annual Interest Rate) ÷ 12 \`\`\`
**Total Interest Cost Formula:** \`\`\` Total Interest = Monthly Payment × Term (months) \`\`\`
**Example Calculation:** - Bridge loan amount: \$480,000 - Annual interest rate: 8.5% - Term: 12 months
\`\`\` Monthly Payment = (\$480,000 × 0.085) ÷ 12 = \$3,400/month Total Interest = \$3,400 × 12 = \$40,800 \`\`\`
**Available Equity Formula:** \`\`\` Equity Available = Current Home Value − Current Mortgage Balance \`\`\`
**Default Bridge Loan Amount:** Most lenders base the bridge loan on the gap between your new home's purchase price and the equity you can deploy as a down payment: \`\`\` Bridge Loan Amount = New Home Price − Available Equity \`\`\`
**Net Cash at Closing (when current home sells):** \`\`\` Net Cash = Current Home Sale Price − Mortgage Payoff − Bridge Loan Repayment \`\`\`
The net cash figure represents the money that remains in your hands after all obligations are settled. A positive number means you walk away with cash; a negative number indicates you would owe money at closing, which is a warning sign to address before proceeding.
When to use a bridge loan
Bridge loans are best suited to specific situations. Consider one if:
- **You need to move quickly** — You have found your ideal home and cannot afford to wait for your current home to sell before making an offer. - **You are in a competitive market** — Removing the home sale contingency from your offer makes it far more competitive and can help you win in multiple-offer situations. - **You have substantial equity** — The more equity you hold in your current home, the lower your bridge loan amount needs to be, reducing your interest costs and risk exposure. - **Your current home will sell quickly** — If your property is in a desirable area with strong demand, the risk of a prolonged bridge loan is lower. - **You can afford the monthly carrying cost** — You must comfortably cover the bridge loan interest payments alongside any remaining mortgage payments on your current home.
Bridge loans are generally **not recommended** if: - Your current home has uncertain or slow market demand - You have limited equity (less than 20% of current home value) - You cannot absorb two months or more of carrying costs if the sale is delayed - Your credit score or income would make qualifying for a bridge loan difficult - Less expensive alternatives exist, such as a HELOC, personal loan, or gift funds
How to use this calculator
1. **Enter your current home value** — Use your best estimate of what your home will sell for. Be realistic; overestimating creates a false sense of available equity. 2. **Enter your current mortgage balance** — The remaining principal on your existing mortgage. Your lender can provide an exact payoff quote. 3. **Enter the new home purchase price** — The agreed or expected purchase price of the property you are buying. 4. **Review the auto-calculated bridge loan amount** — The calculator automatically estimates the loan amount based on your equity and new home price. You can override this with a specific figure if your lender has quoted you a different amount. 5. **Enter the interest rate** — Use the rate your lender has quoted, or enter a typical market rate (8–10% is common for bridge loans). Check with multiple lenders for current rates. 6. **Select the loan term** — Choose the number of months you expect to carry the bridge loan. Shorter is generally better. Most bridge loans run 6 to 12 months. 7. **Click Calculate** — Your results appear immediately, including monthly payments, total interest, equity used, net cash at closing, and a full month-by-month breakdown.
FAQs
Q: What is a typical bridge loan term? A: Bridge loans typically have terms of 6 to 12 months, though some lenders offer terms up to 24 months. The goal is always to sell your current home as quickly as possible to minimize interest costs. Most real estate attorneys and financial advisors recommend planning for a term no longer than what your local market conditions support for a typical home sale.
Q: What are typical bridge loan interest rates? A: Bridge loan rates are typically 2 to 5 percentage points higher than conventional 30-year mortgage rates. If the prevailing 30-year mortgage rate is around 6.5%, expect bridge loan rates in the range of 8.5% to 11.5%. Rates vary by lender, loan size, your credit profile, and whether the loan is offered by a bank, credit union, or private lender.
Q: How much can I borrow with a bridge loan? A: Most lenders allow you to borrow up to 80% of the combined value of both properties (your current home and the new one). The actual loan amount is typically sized to cover the gap between what you owe on your current home and what you need for your new home purchase. Lenders will also assess your income and ability to carry both the bridge loan payment and any remaining mortgage payment simultaneously.
Q: Do I need to make payments on a bridge loan? A: Yes, most bridge loans require monthly interest-only payments during the loan term. Some lenders offer deferred payment options where interest accrues and is paid at loan payoff, but these arrangements are less common and typically result in higher total costs. Always confirm the payment structure with your lender before proceeding.
Q: What happens if my current home does not sell before the bridge loan matures? A: If your home has not sold when the bridge loan comes due, you will need to either refinance the bridge loan (extend the term), pay it off from other funds, or in a worst case, face default. Many lenders will work with you to extend the term if needed, but this adds cost and uncertainty. This risk is one of the most important factors to weigh before taking a bridge loan.
Q: Are there alternatives to a bridge loan? A: Yes. A Home Equity Line of Credit (HELOC) is often cheaper if you qualify, since it uses your current home as collateral and typically carries lower rates. You could also negotiate a longer closing period on your new purchase, make an offer contingent on your home sale, use savings for the down payment, or explore 401(k) loans as a short-term funding source. Each alternative has trade-offs; consult a financial advisor to compare them based on your situation.
Q: Are bridge loan interest payments tax-deductible? A: In many cases, bridge loan interest may be deductible as mortgage interest if the loan is secured by your primary residence, but tax rules are complex and change regularly. Consult a qualified tax professional to understand how bridge loan interest applies to your specific situation.
