What Is a Bridge Loan?

A bridge loan is a short-term financing solution designed for homeowners who want to purchase a new property before selling their existing one. Think of it as a financial “bridge” that spans the gap between two real estate transactions — giving you immediate access to the equity locked in your current home so you can act on a new purchase without waiting months for your house to sell.

Bridge loans are typically secured by your current home and carry terms of 6 to 12 months, though some lenders offer up to 24 months. Unlike traditional mortgages, bridge loans almost always feature interest-only monthly payments with a balloon payment (the full principal balance) due at the end of the term. This structure keeps monthly costs lower during the bridge period while you work on selling your existing property. If you are building a new home rather than buying an existing one, you will likely also need a construction loan to finance the build itself.

According to the Consumer Financial Protection Bureau (CFPB), bridge loans are considered “non-traditional mortgage products” and are not as heavily regulated as conventional mortgages. This means terms, rates, and fees can vary significantly between lenders, making it essential to shop around and use a bridge loan calculator to understand the true cost.

How Bridge Loans Work: Step by Step

Understanding the mechanics of bridge loans helps you evaluate whether this financing strategy makes sense for your situation. Here's how the process typically unfolds:

Step 1: Assess your equity. The lender evaluates the market value of your current home and subtracts your remaining mortgage balance. Most bridge lenders require at least 20% equity in your existing home. For example, if your home is worth $400,000 and you owe $250,000, you have $150,000 in equity — a strong position for bridge financing. The concept of equity-based borrowing is similar to an auto equity loan, where you borrow against the value of your vehicle minus what you owe.

Step 2: Determine the bridge loan amount. The loan amount is typically based on the down payment you need for the new home. If you're buying a $500,000 home with 20% down ($100,000), and you plan to use the equity from your current home sale to cover this, the bridge loan provides that $100,000 now rather than making you wait.

Step 3: Approval and closing. Bridge loans move fast — many lenders can close in as little as two weeks, compared to 30-45 days for a conventional mortgage. This speed is one of the primary advantages of bridge financing, especially in competitive housing markets where sellers prefer quick closings.

Step 4: Interest-only payments. During the bridge period, you make monthly interest-only payments. On a $100,000 bridge loan at 9.5%, your monthly payment would be approximately $792 — much lower than a fully amortizing payment would be.

Step 5: Sale and repayment. Once your existing home sells, you use the proceeds to pay off the bridge loan principal (the balloon payment), any remaining interest, and your existing mortgage. The transaction is complete, and you're settled in your new home. If you are also selling a vehicle as part of your move, our auto loan private seller guide covers the process of handling vehicle transactions between individuals.

Bridge Loan vs. Home Equity Loan vs. HELOC

Bridge loans aren't the only way to tap your home equity for a new purchase. Two common alternatives — home equity loans and HELOCs — each have distinct advantages and trade-offs. Understanding the differences helps you choose the best tool for your situation.

Bridge loans provide a lump sum with interest-only payments and a balloon payment at term end. They close in 2-3 weeks, carry rates of 8-13%, and typically charge origination fees of 1-3%. The primary advantage is speed: when you find the perfect home in a competitive market, a bridge loan lets you act immediately.

Home equity loans offer a lump sum with fixed monthly payments amortized over 5-30 years. Rates are typically 7-9% with closing costs of 2-5% of the loan. They take 2-6 weeks to close. The monthly payment obligation is higher than a bridge loan because you're paying both principal and interest, but the longer term gives you more flexibility. Some homeowners also consider borrowing from their 401(k) retirement account as an alternative source of bridge funds, though this comes with significant opportunity costs.

HELOCs (Home Equity Lines of Credit) provide a revolving credit line with variable rates, typically 7-9%. They take 30-45 days to close and have lower upfront costs. However, the variable rate creates payment uncertainty, and some lenders freeze HELOCs in declining housing markets.

The Federal Reserve tracks average home equity lending rates in its Consumer Credit report. As of early 2026, home equity rates average 8.5%, making bridge loans (at 9-11%) only marginally more expensive on a monthly basis while offering significantly faster closing times.

Current Bridge Loan Rates and Terms (2026)

Bridge loan rates in 2026 typically range from 8% to 13%, depending on the lender, your creditworthiness, equity position, and the local real estate market. Here's what to expect from different types of lenders:

Banks and credit unions tend to offer the lowest rates (8-10%) but have stricter qualification requirements, including higher credit scores (700+), lower debt-to-income ratios, and more documentation. They may also take longer to close. Our credit score guide explains how lenders use your score across all types of lending decisions.

Mortgage companies and online lenders offer mid-range rates (9-11%) with faster processing and more flexible qualification criteria. Many specialize in bridge lending and can close in 10-14 days.

Private and hard money lenders charge the highest rates (11-13%) but have the most flexible requirements and fastest closings (sometimes under a week). They focus primarily on the property's value rather than your income or credit score.

Beyond interest rates, pay attention to these fee components: origination fees (1-3% of the loan), appraisal fees ($300-$600), title and escrow fees ($500-$2,000), and possible extension fees if you need the loan beyond the original term (typically 0.25-0.50% per month). These costs add up quickly, so use our loan payoff calculator to see how paying off the bridge loan early could save you significant interest.

Bridge Loan Costs: What You'll Actually Pay

The true cost of a bridge loan goes beyond the quoted interest rate. Let's break down a realistic example so you can see exactly where your money goes:

Example scenario: You're buying a $500,000 home with 20% down ($100,000) and taking a 12-month bridge loan at 9.5% with a 2% origination fee.

Monthly interest payment: $100,000 × 9.5% ÷ 12 = $791.67 per month. Over 12 months, that's $9,500 in total interest. Origination fee: $100,000 × 2% = $2,000 (paid at closing). Additional closing costs: Appraisal ($400), title ($800), attorney/escrow ($500) = approximately $1,700. Total cost of the bridge loan: $9,500 + $2,000 + $1,700 = $13,200, or about 13.2% of the loan amount.

If your home sells in 6 months instead of 12, your interest cost drops to $4,750, bringing total costs down to approximately $8,450. This is why selling your existing home quickly is the most important factor in controlling bridge loan costs. You may also want to consider paying off any outstanding vehicle loans — such as an auto loan, RV loan, or motorcycle loan — before taking on bridge financing to reduce your total debt load.

Who Should (and Shouldn't) Use a Bridge Loan

Bridge loans are a powerful tool in the right circumstances, but they're not ideal for every buyer. Here's an honest assessment of when bridge loans make sense — and when you should explore alternatives.

A bridge loan makes sense when: You've found your next home in a competitive market and need to act fast. You have significant equity (30%+) in your current home. Your current home is in a strong seller's market with low days-on-market. You can comfortably afford two mortgage payments temporarily. You've been pre-approved for a new mortgage and the bridge loan is solely for the timing gap.

Consider alternatives when: Your current home has been on the market for months without offers — a bridge loan adds cost while you wait. You have less than 20% equity in your current home. Your debt-to-income ratio is already stretched. The housing market in your area is cooling or declining. You can negotiate a later closing date on the new purchase to allow time for your sale. An unsecured personal loan is another option for smaller bridge amounts, though rates tend to be higher since no collateral is involved.

Financial advisors generally recommend that bridge loan borrowers have a concrete plan for selling their existing home — ideally with a listing agreement already in place or even a pending offer. The CFPB notes that borrowers should carefully evaluate whether they can afford to carry two housing payments simultaneously if their existing home takes longer to sell than expected.

How to Use This Bridge Loan Calculator

Our bridge loan calculator is designed to give you a clear picture of what bridge financing will actually cost. Here's how to get the most accurate estimate:

Enter your current home value — use a recent appraisal, Zillow estimate, or a comparable sales analysis from your real estate agent. Being conservative here protects you from overestimating your equity.

Enter your existing mortgage balance — check your latest statement for the exact payoff amount. Remember that your payoff amount may be slightly higher than your current balance due to accrued interest. If you have other debts like a boat loan or personal loan, factor those into your overall financial picture as well.

Enter the new home purchase price and down payment — the calculator will determine how much bridge financing you need based on the down payment required for your new mortgage.

Adjust the interest rate and origination fee — if you've received quotes from lenders, enter those exact numbers. Otherwise, 9.5% interest and 2% origination are reasonable starting points for 2026 market conditions.

Experiment with the loan term — try different durations to see how timing affects your costs. You'll notice that the relationship between loan term and total cost is linear for interest-only loans: doubling the term doubles the interest.

The results show your monthly interest-only payment, total interest cost, origination fee, and total financing cost. Use the payment schedule to see exactly what you'll owe each month and at the balloon payment. Remember, these are estimates — actual terms will depend on your lender, credit profile, and property details.
