How Does a Bridge Loan Work? A Move-Up Buyer's Step-by-Step Guide
Mike Certo · Cornerstone First Mortgage · NMLS #260555 ·
The name says everything. A bridge loan literally bridges the gap — between the home you're in and the one you want. Most move-up buyers face the same dilemma: you can't afford the new home without the equity in the current one, but you can't tap that equity until you sell. The bridge loan breaks that deadlock. You close on the new home first. You sell the old one from a position of strength. Then the proceeds retire the bridge and you're done. This page walks through every step of that sequence, explains what happens with your money, and tells you who this works for — and who it doesn't.
The Five-Step Bridge Loan Sequence
Step 1: Your Current Home's Equity Is Assessed
The lender looks at what your current home is worth today and subtracts your existing mortgage balance. The remaining equity is the pool they will lend against. Not all of it — most programs lend up to a combined loan-to-value limit, typically 70–80% across both properties. This assessment sets the ceiling on how much bridge financing is available and confirms there is enough equity to make the structure work.
Step 2: The Bridge Covers Your Down Payment on the New Home
The bridge loan funds are used to make the down payment on your new purchase. You close on the new home as a buyer with no sale contingency attached. From the seller's perspective, your offer looks the same as anyone else's clean offer. You are not asking them to wait for your current home to sell. The bridge is already in place.
Step 3: You Close on the New Home While the Old One Is Still Yours
For a period — typically 90 days in a normal Phoenix-area market, up to 180 days in slower conditions — you own both properties. The bridge loan payment during this window is usually interest-only. That keeps the monthly obligation lower than a fully amortizing loan, which matters because you are still carrying the mortgage on the current home at the same time. The two payments together represent your total housing cost during the bridge period.
Step 4: You List and Sell the Current Home
Now you sell from a position that most sellers dream about: your home is vacant, fully prepared for staging, and you are not under pressure to accept a low offer because you need to close by a specific date to fund the new purchase. Vacant homes typically show better and photograph better than occupied ones. You control the timing. If the first offer isn't right, you can wait for a better one.
Step 5: The Sale Pays Off the Bridge — and You Keep the Rest
When your current home closes, the proceeds flow in this order: (1) pay off the existing mortgage on the old home; (2) pay off the bridge loan balance; (3) any remaining equity goes to you. The bridge closes automatically on payoff — there is no lingering balance, no refinance required, no additional step. You're left with your new home and the net equity from the sale in your pocket.
What Is Used as Collateral for the Bridge Loan?
The bridge loan is secured against the equity in your current home. The lender places a lien on the current property (behind your existing mortgage if one exists). Some lenders cross-collateralize both properties — using both homes as security — which can allow slightly higher loan amounts in some scenarios. Either way, the key variable is how much equity exists in the current home relative to what the bridge is asking to borrow. The cleaner that math is, the cleaner the approval.
Why Are Bridge Loan Payments Interest-Only?
Amortizing a bridge loan would mean building equity in a loan you plan to pay off in 90–180 days — which makes no sense for either party. Interest-only structure is designed for the bridge's short lifespan. You pay only the cost of using the capital, not a principal reduction. The principal goes away in one lump when the sale closes. This structure also keeps the monthly payment as low as possible during the window when you are carrying two homes — which reduces the strain on your cash flow and simplifies underwriting.
What Does a Typical Arizona Bridge Timeline Look Like?
In the Phoenix metro, homes in good condition in popular submarkets (East Valley, North Scottsdale, Chandler/Gilbert corridor) commonly sell within 30–60 days when priced correctly. A 90-day bridge gives a meaningful buffer. In slower-moving markets or for higher-priced properties that attract a narrower buyer pool, 120–180 days is more realistic. The bridge term should be set based on honest market assessment — not optimistic hope. Mike can help you map the realistic selling window for your specific property and location.
How Does a Bridge Loan Compare to a Contingent Offer?
A contingent offer says: "I'll buy your home once mine sells." In a competitive market, that is a significant ask. The seller has to accept the risk that your home might take months to sell, fall out of escrow, or encounter problems. Many sellers — especially in hot Arizona submarkets — simply pass on contingent offers in favor of clean ones. A bridge loan eliminates the contingency. Your offer says nothing about the current home. It stands on its own, backed by your financing and your credit, just like any other buyer. In multiple-offer situations, this distinction often determines whether you win the house.
Who Is a Good Candidate for a Bridge Loan?
The strongest fit is a move-up buyer who has owned their current home for five or more years and has built substantial equity — enough to cover the bridge loan plus leave a comfortable LTV buffer. FICO score in the upper 600s or better. Income that can support both mortgage payments if the underwriter requires it. A current home in good showing condition without major deferred maintenance. These buyers get the most value from the bridge structure because the math is clean and the risk is low.
When Is a Bridge Loan the Wrong Tool?
Bridge loans don't work when the math doesn't support them. If your current home has minimal equity after the existing mortgage, there is not enough collateral to fund the bridge. If your home needs significant repairs before it can sell at a price that supports the loan structure, the timeline assumptions fall apart. If your FICO score has challenges, fewer lenders will offer bridge products and the ones that do will price the risk accordingly. In those scenarios, a contingent offer or Cornerstone's backup contract structure may be a more appropriate fit. A quick call with Mike will clarify which path makes sense for your specific situation.

Frequently Asked Questions
What happens if I can't afford two mortgage payments?
Some bridge programs underwrite based on the combined payment of both homes. Others look only at the new home's payment and treat the bridge as a temporary obligation backed by the pending sale. The underwriting approach varies by lender and structure. If carrying two payments is a concern, bring that question up at the start — the right program design can address it, or an alternative structure may be a better fit.
How long does it take to get a bridge loan?
Bridge loans typically close faster than traditional purchases because the approval process focuses primarily on the equity position in the current home rather than a complex income underwrite. Many bridge loans close in 7–15 business days. The timeline is driven by the appraisal of the current home and whatever documentation the lender requires. Starting the conversation before you are under contract on the new home gives you the most flexibility.
What are the typical costs of a bridge loan?
Costs include an origination fee (often 1–2 points), standard closing costs, and monthly interest payments during the bridge period. The interest-only payment is based on the bridge loan amount and the rate. Total cost depends on the bridge amount, the rate, and how long the bridge is active. See the bridge loan rates page for a breakdown of every pricing component and how to compare quotes correctly.
What if my home doesn't sell in time?
Bridge loans include extension options in most cases — at a cost. If the current home is taking longer to sell, talk to your lender about extension terms before the original term expires. In extreme cases where the home cannot sell at a price that covers the mortgage and bridge balance, you would need to work through the options with your lender. The best protection is honest pricing upfront and a realistic bridge term based on actual market conditions — not optimistic assumptions.
