TL;DR: Buying Before You Sell
- Bridge loans provide short-term financing (6 to 12 months) at interest rates typically ranging from 8.5% to 11%, with origination fees of 1% to 2.5% of the loan amount.
- HELOCs offer a lower-cost alternative (averaging around 7% to 9% variable rates) but require 2 to 6 weeks to set up and may not work in fast-moving markets.
- Buy-before-you-sell programs from companies like Knock, HomeLight, and Homeward charge 1.9% to 3.5% in program fees but include guaranteed backup offers if your home does not sell.
- Home sale contingencies cost nothing upfront but weaken your offer: sellers often prefer non-contingent bids, especially in competitive markets.
- An experienced real estate agent who has handled simultaneous buy-sell transactions can save you thousands in carrying costs and help you choose the right financing strategy.
The Buy-Before-You-Sell Challenge: Why Timing Is Everything
Selling your current home and buying a new one at the same time is one of the most stressful logistical challenges in real estate. If you sell first, you might end up in temporary housing, moving twice, or scrambling to find your next home under pressure. If you buy first, you could be stuck paying two mortgages simultaneously while waiting for your old home to close.
This is the classic chicken-and-egg dilemma that millions of move-up buyers face every year. According to the National Association of REALTORS (NAR), the median existing home price reached $396,800 in January 2026, and homes spent a median of 36 days on the market in late 2025. With prices at these levels, carrying two properties even briefly can cost thousands of dollars in overlapping mortgage payments, insurance, taxes, and utilities.
The good news: you have more options than ever for bridging the gap between your current home and your next one. From traditional bridge loans and HELOCs to modern buy-before-you-sell programs and creative structuring strategies, each approach carries different costs, risks, and timelines. This guide breaks down every major option so you can choose the path that best fits your financial situation, risk tolerance, and local market conditions.

A bridge loan is a short-term loan that uses the equity in your current home to help finance the purchase of a new one. Think of it as temporary gap financing designed to "bridge" the period between buying your next property and selling your current one. The Consumer Financial Protection Bureau (CFPB) classifies bridge loans as temporary financing with a term of 12 months or less, and they are exempt from certain Ability-to-Repay requirements under federal lending rules.
How Bridge Loan Financing Works for Homeowners
When you take out a bridge loan, the lender evaluates the equity in your current home, your creditworthiness, and the details of your intended purchase. The loan amount is typically based on the difference between your current home's appraised value and your outstanding mortgage balance, minus a cushion for the lender's risk.
Most bridge loans work in one of two ways. The first approach uses the bridge loan to cover your down payment and closing costs on the new home while you continue making payments on your existing mortgage. The second approach rolls your current mortgage into the bridge loan, creating a single larger loan that gets paid off when your old home sells.
Apply and Get Approved
Submit documentation including proof of income, current mortgage statements, and details about both properties. Lenders typically look for a credit score in the mid-700s and sufficient equity in your current home.
Receive Your Funds
Bridge loans are disbursed as a lump sum, often within 5 to 14 days of approval. This speed is one of the primary advantages over other financing methods.
Buy Your New Home
Use the bridge loan proceeds for your down payment and closing costs. Because you have cash in hand, you can make a non-contingent offer, which is far more competitive than an offer that depends on selling your current home first.
Sell Your Current Home and Repay
When your current home sells, the proceeds go toward repaying the bridge loan. Most borrowers repay the loan within 3 to 6 months, though terms can extend up to 12 months.
Bridge Loan Costs: Rates, Fees, and Total Expense
Bridge loans carry higher costs than traditional mortgages because they are short-term, higher-risk products. Here is what you can expect to pay:
| Cost Component | Typical Range | Notes |
|---|---|---|
| Interest Rate | 8.5% to 11% | Often prime rate plus 2% or higher; varies by lender and borrower profile |
| Origination Fee | 1% to 2.5% | Charged as "points" on the loan amount |
| Appraisal Fee | $400 to $700 | Required to determine current home value |
| Closing Costs | 1.5% to 3% | Title insurance, escrow, recording, and notary fees |
| Loan Term | 6 to 12 months | Residential bridge loans are commonly written for 11 months |
Who Offers Bridge Loans?
Not all lenders offer residential bridge loans. Traditional banks and credit unions may have bridge loan programs, but they often focus on longer-term products. Many bridge loans are originated by private lenders or specialty mortgage companies that focus on short-term real estate financing. Some major mortgage companies like Rocket Mortgage offer bridge loan products, and regional banks in competitive housing markets often maintain active bridge loan programs.
When shopping for a bridge loan, compare at least three lenders and ask for a detailed breakdown of all fees. Unlike traditional mortgages, bridge loans may not always be covered by the Real Estate Settlement Procedures Act (RESPA), depending on how the loan is structured. However, bridge loans used to purchase a primary residence do fall under RESPA disclosure requirements.
Is a Bridge Loan Hard to Get? Requirements and Qualifications
Bridge loan requirements are generally stricter than traditional mortgage criteria in some areas and more flexible in others. Most lenders look for:
A credit score of 680 or higher, with many lenders preferring scores in the mid-700s. Sufficient equity in your current home, typically requiring a combined loan-to-value (CLTV) ratio of 80% or less across both properties. Proof that you can afford to carry payments on both the bridge loan and your new mortgage simultaneously. A clear exit strategy, meaning your current home should be either already listed or in a condition to sell quickly.
Bridge loans tend to be more flexible than conventional mortgages when it comes to debt-to-income (DTI) ratios and income documentation, since the lender's primary concern is the collateral value of the property rather than the borrower's long-term repayment capacity.
Using a HELOC to Buy a New Home Before Selling
A home equity line of credit (HELOC) is another popular way to access the equity in your current home to fund a new purchase. According to the CFPB's consumer guide on HELOCs, lenders typically set the credit limit by taking a percentage (often 75% to 85%) of the home's appraised value and subtracting the outstanding mortgage balance.
With a HELOC, you draw the funds you need for a down payment on your new home and then repay the line of credit when your current home sells. During the draw period, you pay interest only on the amount borrowed, not the full credit limit, which makes this a cost-effective option if you need only a portion of your equity.
HELOC vs. Bridge Loan: Key Differences for Move-Up Buyers
| Feature | Bridge Loan | HELOC |
|---|---|---|
| Disbursement | Lump sum | Draw as needed (revolving credit) |
| Interest Rate | 8.5% to 11% (often fixed) | 7% to 9% (typically variable) |
| Loan Term | 6 to 12 months | 5 to 10 year draw period; 10 to 20 year repayment |
| Time to Fund | 5 to 14 days | 2 to 6 weeks |
| Credit Score Needed | Mid 700s preferred | High 600s to low 700s |
| Interest Paid On | Full loan amount | Only the amount drawn |
| Best For | Fast closings; competitive markets | Flexible needs; longer selling timelines |
| Tax Deductible | May be deductible if used to buy a home | Deductible when used to purchase a home (consult a tax advisor) |
HELOCs are generally the more affordable option, with lower interest rates and the flexibility to borrow only what you need. However, they take longer to set up and come with variable interest rates that could increase during your holding period. If you are in a fast-moving market where sellers will not wait, a bridge loan's speed advantage could outweigh its higher cost.
One important consideration: if you already have a HELOC in place on your current home, you can use it immediately without going through a new application process. This makes HELOCs an excellent proactive strategy for homeowners who anticipate a future move. Setting up a HELOC before you start house-hunting gives you a ready source of funds when you find the right property.
The 80-10-10 Piggyback Loan: An Alternative Structure
The 80-10-10 piggyback loan is a financing structure that uses two mortgages simultaneously to purchase a home. The first mortgage covers 80% of the purchase price, a second mortgage (usually a HELOC) covers 10%, and you put down 10% in cash. While the piggyback loan was originally designed to help buyers avoid private mortgage insurance (PMI), it can also work for move-up buyers who do not have a full 20% down payment available because their equity is tied up in their current home.
For move-up buyers specifically, the 80-10-10 structure reduces the amount of cash needed at closing. If your old home has not yet sold, you only need to come up with 10% in cash rather than 20%, and you avoid the added expense of PMI on your primary loan. Once your current home sells, you can use the proceeds to pay off the second mortgage entirely.
However, qualifying for two mortgages simultaneously requires strong credit (typically 680 or higher for the primary loan and 660 to 680 for the second mortgage) and a debt-to-income ratio below 43%. You will also pay closing costs on both loans, which can offset some of the savings from avoiding PMI.
Home Sale Contingencies: The Zero-Cost Option
A home sale contingency is a clause in your purchase offer that makes the deal dependent on the successful sale of your current home. If your home does not sell within the specified window (typically 30 to 60 days), you can walk away from the purchase without losing your earnest money deposit.
The NAR notes that home sale contingencies are among the riskiest contingency types from a seller's perspective. In competitive markets, sellers frequently reject contingent offers in favor of buyers who can close without conditions. According to industry data, roughly 7% of real estate purchase contracts were terminated in 2022, and home sale contingencies were among the most common reasons for deal failures.
How to Strengthen a Contingent Offer
If a contingent offer is your only option, there are strategies to make it more competitive. Offer a larger earnest money deposit to signal commitment. Get your current home listed and under contract before making your new offer (a settlement contingency is stronger than a sale-and-settlement contingency). Include a kick-out clause that gives the seller the right to continue showing the home and accept other offers, with you getting 72 hours' notice to either remove the contingency or withdraw. Price your offer competitively or slightly above asking to compensate the seller for the added risk.
Keep in mind that even with these strategies, contingent offers remain the weakest option in a seller's market. When multiple buyers are competing for the same property, most listing agents will advise their clients to choose a non-contingent offer.

Get Matched with a Local ExpertRent-Back Agreements: Selling First Without Moving Twice
A rent-back agreement (also called a lease-back or post-settlement occupancy agreement) allows you to sell your home and remain in it as a tenant for a set period after closing, typically up to 60 days. This gives you time to close on your new purchase without the expense and hassle of moving into temporary housing.
Here is how it works: you and the buyer negotiate terms for rent (often equivalent to the buyer's new monthly mortgage payment), a security deposit, responsibility for utilities and maintenance, and a firm move-out date. The agreement is included as part of the sales contract and signed at closing. Most lenders allow rent-back periods up to 60 days without issues, though longer periods may complicate the buyer's financing.
Rent-back agreements are particularly useful in balanced or buyer-friendly markets where you can sell at a fair price while retaining the flexibility to complete your next purchase. However, in a hot market, the buyer may not agree to a rent-back, especially if they need to move in quickly.
Buy-Before-You-Sell Programs: Knock, HomeLight, and Homeward
A newer category of real estate service has emerged to solve the buy-before-you-sell problem. Companies like Knock, HomeLight, and Homeward offer structured programs that advance you a portion of your home equity, allow you to make a competitive offer on your new home, and provide a guaranteed backup purchase offer on your current property if it does not sell on the open market.
How These Programs Work
While specific details vary by provider, the general structure follows a similar pattern. The company evaluates your current home's value and your financial profile. You receive an equity advance or bridge loan to fund your new home purchase. You move into your new home and list your current property on the open market with a real estate agent. When your current home sells, you repay the advance from the sale proceeds. If it does not sell within a specified timeframe (typically 120 to 180 days), the company purchases your home at a pre-agreed price.
| Program | Program Fee | Backup Offer? | Timeline | Service Area |
|---|---|---|---|---|
| Knock Bridge Loan | 2.25% of list price + $1,850 | Yes, at approximately 80% of market value | Interest-free for 6 months | 26 states |
| HomeLight Buy Before You Sell | 2.4% of departing home sale | Yes, guaranteed within 120 days | Up to 120 days to sell | Most U.S. cities |
| Homeward | 1.9% to 3.5% convenience fee | Yes, within 180 days | 90 days included; extensions at 1%/month | 13 states + D.C. |
| Orchard Move First | $2,900 flat fee + brokerage fees | Yes | Varies | Limited markets |
The main advantage of these programs is the guaranteed exit: you know your home will sell, one way or another. The main disadvantage is cost. When you add program fees, potential carrying costs, and the fact that backup offers are typically well below full market value, the total expense can range from 5% to 13% of your home's sale price. Still, for homeowners in competitive markets where timing is critical, the certainty and convenience can be worth the premium.
These programs work best for homeowners with significant equity, homes in good condition, and properties priced within the programs' eligibility ranges (typically up to $1.5 million in most markets). Homes needing major repairs or in very slow markets may not qualify.

How to Choose the Right Bridge Financing Strategy
The best option for your situation depends on several factors: how much equity you have, how quickly you need to act, your local market conditions, and your tolerance for financial risk. Here are some common scenarios to guide your decision:
If You Are in a Hot Seller's Market with Low Inventory
A bridge loan or buy-before-you-sell program is your strongest play. Speed matters, and sellers will not wait for your home to sell. The ability to make a clean, non-contingent offer could mean the difference between winning and losing the home you want. The extra cost is often justified by the competitive advantage.
If You Have Time and Want to Minimize Costs
A HELOC is typically the most cost-effective option. If you already have one in place, even better. The lower interest rate and flexible draw structure keep your costs down, and the longer repayment timeline gives you breathing room if your home takes longer to sell.
If You Are Risk-Averse and Want a Guaranteed Exit
A buy-before-you-sell program provides the most certainty. Yes, you will pay a program fee, but you get peace of mind knowing that your home will sell, either on the open market or through the company's guaranteed purchase. This is especially valuable if you are relocating for work with a firm deadline.
If You Are in a Buyer's Market or Have a Unique Property
A home sale contingency might work here. When properties are sitting on the market and sellers are more willing to negotiate, a contingent offer with a strong earnest money deposit and a kick-out clause becomes more viable. You save on financing costs entirely.
Why Agent Experience Matters for Simultaneous Transactions
Buying and selling at the same time is not a standard real estate transaction. It requires careful coordination of timelines, contracts, and financing. An experienced agent who has managed these dual transactions before can help you evaluate which financing strategy makes sense for your equity position and local market, time your listing to coincide with your purchase timeline, negotiate terms like rent-back agreements or extended closings, and connect you with lenders who specialize in bridge financing. If you are relocating for work, coordination becomes even more critical: check out our guide to buying and selling a home when relocating for additional strategies.
The right agent can also help you avoid one of the biggest pitfalls of simultaneous transactions: mispricing your current home. If your home is priced too high and sits on the market, your bridge loan or HELOC interest keeps accruing, your buy-before-you-sell program timeline shrinks, and your carrying costs multiply. A top-performing listing agent who understands your local market can price your home to sell quickly while maximizing your return, reducing the total cost of your bridge financing.

What is a bridge loan in real estate and how does it work?
A bridge loan is a short-term loan (typically 6 to 12 months) that uses the equity in your current home to help finance the purchase of a new one. You receive a lump sum that can be applied toward your down payment and closing costs on the new property. When your current home sells, the proceeds are used to repay the bridge loan. Interest rates are higher than traditional mortgages, generally ranging from 8.5% to 11%, and lenders typically charge origination fees of 1% to 2.5%.
Is a bridge loan hard to get?
Bridge loans can be more accessible than conventional mortgages in some ways because lenders focus primarily on the value of your collateral (your current home's equity) rather than strict income or DTI requirements. However, most lenders prefer borrowers with credit scores in the mid-700s, a CLTV ratio of 80% or less, and a clear plan to sell the current property. If you have substantial equity and good credit, qualifying should not be difficult. If your equity is limited or your home may be challenging to sell, lenders may be more cautious.
Can I use a HELOC instead of a bridge loan to buy before I sell?
Yes, a HELOC can function similarly to a bridge loan by providing funds for a down payment on a new home. HELOCs typically offer lower interest rates (around 7% to 9%), longer repayment terms, and more flexibility since you only pay interest on the amount you draw. The main drawback is that HELOCs take longer to set up (2 to 6 weeks) and have variable interest rates. If you already have a HELOC in place, it can be one of the most efficient and affordable ways to bridge the gap between buying and selling.
What are buy-before-you-sell programs like Knock and HomeLight?
These programs are structured services that advance you a portion of your home equity so you can purchase a new home before selling your current one. They typically charge a program fee (1.9% to 3.5% of the home sale price) and provide a guaranteed backup purchase offer on your current home if it does not sell on the open market within a specified timeframe (usually 120 to 180 days). The main benefit is certainty: you know your home will sell. The main cost is the program fee, plus potential carrying costs like property taxes and insurance while you wait for the sale.
What is an 80-10-10 piggyback loan and can it help me buy before selling?
An 80-10-10 piggyback loan is a two-mortgage structure where the first mortgage covers 80% of the new home's purchase price, a second mortgage (usually a HELOC) covers 10%, and you put down 10% in cash. For move-up buyers, this reduces the cash needed at closing, which is helpful if most of your wealth is tied up in your current home. Once your current home sells, you can pay off the second mortgage. You will need strong credit (typically 680+), a DTI ratio under 43%, and the ability to qualify for two mortgages simultaneously.
How does a rent-back agreement work when selling a home?
A rent-back agreement allows you to sell your home and remain in it as a tenant for a period after closing, usually up to 60 days. You and the buyer negotiate the rental rate (often equivalent to the buyer's mortgage payment), security deposit, utility responsibilities, and move-out date. This arrangement gives you time to close on your new home without moving into temporary housing. Lenders typically allow rent-back periods up to 60 days without complications, though longer periods may require special arrangements.
Are bridge loan interest payments tax deductible?
Interest on a bridge loan may be tax deductible if the loan is used to purchase your primary or secondary residence, similar to mortgage interest deductions. The same applies to HELOC interest when the funds are used for a home purchase. However, tax rules are complex and individual circumstances vary. You should consult with a qualified tax advisor to understand how bridge loan interest deductions apply to your specific situation. Remember that you must itemize deductions to claim mortgage interest, which may not benefit everyone.
What happens if my home does not sell before the bridge loan expires?
If your home has not sold by the end of the bridge loan term, you will need to either extend the loan (if the lender allows it, potentially with additional fees), refinance into a longer-term loan, or sell the home at a reduced price. This is one of the primary risks of bridge financing. Before taking out a bridge loan, make sure you have a realistic assessment of your home's marketability and consider having a contingency plan, such as a price reduction strategy or the option to rent out your current property. Some buy-before-you-sell programs eliminate this risk by offering guaranteed purchase prices.
