Both a bridge loan and a private second mortgage let you borrow against equity you already have in real estate. Both are typically arranged outside the traditional bank system. And both get mentioned in the same breath when a buyer or seller runs into a timing problem or needs cash the bank won't provide quickly enough.
But they solve different problems, are structured differently, and get discharged differently. Confusing the two — or assuming either one is a quick, interchangeable fix — can create real trouble in a real estate closing. This article compares a bridge loan and a private second mortgage side by side so you can recognize which one actually fits your situation.
Bridge Loan at a Glance
A bridge loan is short-term financing designed to "bridge" a gap between two real estate transactions — most commonly, when the closing date on the home you're buying falls before the closing date on the home you're selling. It lets you access the equity tied up in your current home before that sale actually closes, so you can complete your purchase without waiting for your existing property to change hands.
Bridge financing is typically:
- Secured against the equity in the property you are actively selling, often through the same lender financing your new purchase
- Repaid automatically once your existing sale closes and proceeds are received
- Structured as short-term financing, meant to be resolved in days or weeks rather than months or years
- Coordinated closely by your real estate lawyer, since it depends on two closings lining up correctly
Private Second Mortgage at a Glance
A private second mortgage is a separate loan registered as a second charge on title, behind your existing first mortgage, arranged with a private or alternative lender rather than a bank. Unlike a bridge loan, it isn't tied to a pending sale — it's a way to access equity in a property you intend to keep.
Private second mortgages are typically:
- Secured by a registered charge in second position, ranking behind your existing first mortgage
- Used for longer-term needs: debt consolidation, funding a project, covering a shortfall, or accessing equity a bank won't lend against
- Structured with their own term, payment schedule, and (often, for private lenders) higher cost than a bank product
- Independent of any pending sale — it stays on title until you refinance, sell, or pay it out on its own timeline
Side-by-Side Comparison
| Bridge Loan | Private Second Mortgage | |
|---|---|---|
| Purpose | Cover a timing gap between a sale and a purchase closing | Access equity for a standalone need, unrelated to a pending sale |
| Tied to a sale? | Yes — repaid from your sale proceeds | No — independent of any sale |
| Typical duration | Short-term, days to weeks | Longer-term, with its own set schedule |
| Security position | Usually secured against the property being sold | Registered as a second charge on the property being kept |
| Who typically lends it | Often the same institution financing your purchase | Private or alternative lenders |
| How it ends | Discharged automatically when the sale closes | Paid out, refinanced, or renewed on its own timeline |
Which One Fits Your Situation?
Ask yourself these questions:
- Are you selling a property, and is the timing the problem? If your sale and purchase closing dates don't line up and you need short-term access to equity you already know is coming, a bridge loan is built for exactly that.
- Do you need to keep your current property and access equity anyway? If there's no pending sale and you simply need funds — for debt consolidation, a project, or a shortfall — a private second mortgage is the more natural fit.
- How long do you actually need the money? A gap measured in days or weeks points toward bridge financing. A need that will take longer to resolve points toward a second mortgage with its own term.
- Do you already have financing lined up for your purchase? Bridge loans are usually arranged alongside your purchase financing, often through the same lender, rather than as a standalone product.
What Your Lawyer Handles in Either Case
Whichever product you use, a real estate lawyer's role includes confirming what's already registered against your title, coordinating payout or discharge statements, and making sure any new charge is registered correctly and discharged on schedule once it's paid out. For a bridge loan, that means making sure the sale that repays it actually closes as planned. For a private second mortgage, it means confirming the charge is registered in the correct position behind your existing first mortgage and that the terms match what you agreed to.
Frequently asked questions
Can I use a bridge loan if I'm not also buying a new home?
Bridge loans are specifically designed around the gap between a sale and a purchase. If you're not buying at the same time, a private second mortgage or another financing product secured against your existing equity is generally the more appropriate tool.
Is a private second mortgage the same as a home equity line of credit?
Not usually. A HELOC is typically a revolving line of credit offered by a traditional lender, often in first or second position. A private second mortgage is a fixed-term loan from a private or alternative lender, generally used when a borrower doesn't qualify for bank financing.
What happens if my home sale falls through while I have a bridge loan?
This is a real risk with bridge financing, since it depends on your sale closing as planned. Speak with your lender and lawyer immediately if a sale is at risk — the specific consequences depend on your loan agreement and how the underlying sale unwinds.
Do I need a lawyer for either type of financing?
Yes. Both involve registering (and eventually discharging) a legal charge against your property, and a bridge loan additionally depends on the mechanics of a closing sale and purchase happening correctly. A real estate lawyer coordinates all of this as part of your transaction.
