The short version
You own a house in Rohnert Park with a pile of equity in it. You found the one in Healdsburg. But your down payment is sitting in drywall and you can't touch it until you sell — and you don't want to sell until you know you've got somewhere to go. That's the whole trap, and it's the single most common reason I see good buyers stuck.
There are four ways out, and only one of them is a bridge loan. You can pull equity with a HELOC before you list. You can bridge it with short-term financing secured against the departing home. You can buy with cash or a light loan and reimburse yourself afterward through delayed financing. Or you can sell first and negotiate a rent-back so you don't move twice. The right answer depends on how much equity you have, how tight your debt ratio is, and how fast your current house will actually sell. Let's go through them honestly, including what each one costs.
Why does a contingent offer lose in Sonoma County?
The California purchase contract has an addendum for this — a contingency for the sale of the buyer's property. It's a legitimate tool and it does exactly what it says. It also puts your offer at the back of the line the moment a seller has a second option.
Look at it from the listing side. Two offers, same price. One closes in 30 days on a loan that's already underwritten. The other closes whenever a house in Windsor sells, appraises, and funds — a house the seller has never seen, priced by someone they've never met. Even a strong contingent offer is a bet on a transaction nobody in the room controls. Sellers take the sure thing, and their agents tell them to.
So the practical goal isn't 'get a bridge loan.' It's 'write an offer with no sale contingency on it.' Everything below is a different way of buying that outcome, and some of them are cheaper than people assume.
What is a bridge loan, and how does it actually work?
A bridge loan is short-term financing — usually somewhere in the six-to-twelve-month range — that lets you pull equity out of your current home to close on the next one. It gets paid off in full out of the sale proceeds when your old house closes. That's the whole design. It's a temporary loan with a built-in exit.
Most of them are structured as a lien against the departing residence. Some lenders instead do a second against the new purchase. Either way, the money shows up as your down payment on the new house, and a lot of programs are interest-only — some defer payments entirely until the sale, so you're not carrying two full mortgage payments while your old place sits on the market. That deferral is the feature people actually want.
The number that governs everything is combined loan-to-value on the departing home. Roughly speaking, lenders will let your existing first mortgage plus the bridge add up to somewhere in the 75–80% range of that home's value, and they hold back a cushion for your selling costs. So run the math on your real equity, not your Zillow equity. On a house worth $900,000 with a $400,000 first, the usable bridge is meaningfully less than the $500,000 of paper equity — those ranges shift by lender and by file, so get an actual quote before you plan around a number.
- Term is short — commonly 6 to 12 months, sized to how long the old house should take to sell
- Frequently interest-only, sometimes with payments deferred until your sale closes
- Secured against the departing residence in most structures
- Repaid in full from the sale proceeds at your closing
- Combined LTV on the old home typically lands around 75–80% (approximate — verify for your scenario)
What are my other options besides a bridge loan?
A bridge loan is the loudest option, not always the best one. Three others are worth pricing first.
A HELOC on your current home is usually the cheapest way to get the same result — but the timing is unforgiving. Once your house is listed, most lenders won't open a home equity line on it, and some won't even if you pull the listing that week. If you're twelve months out from moving, open the line now while the house is quiet. I've had clients save five figures in financing costs purely because they made one phone call a year early.
Delayed financing is the move if you have liquid assets or family money you can borrow briefly. You buy the new house with cash, then refinance to pull that cash back out. Fannie Mae's rules let you do that without waiting the usual seasoning period, generally capped at your purchase price plus allowable closing costs and subject to standard cash-out limits. You get a non-contingent cash offer today and a normal 30-year mortgage a month later. Verify the current guidelines for your situation, but this is a well-worn path.
And then there's the unglamorous one: sell first, negotiate a rent-back, and buy from a position of strength with cash in hand. Buyers hate this idea and it works better than almost anything else. You know your exact number, you carry no double payment, and your offer on the next house is as clean as it gets. Rent-backs are commonly capped around 60 days because longer terms can complicate how the lender classifies occupancy on the buyer's loan — worth confirming for your deal, but 30 to 60 days is usually plenty of runway.
- HELOC before listing — cheapest by a wide margin, but you must open it before the house goes on the market
- Bridge loan — most flexible, works when the equity is already tied up and you have no other liquidity
- Delayed financing — buy with cash or borrowed funds, then refinance to put the cash back
- Sell first with a rent-back — no double payment, no financing cost, one move
- Portfolio or securities-backed line of credit — worth asking your advisor about if you hold significant taxable investments
What does a bridge loan cost, and can I qualify?
It's not cheap money, and I'd rather you hear that from me than find out at signing. Bridge rates run well above a standard 30-year, plus origination points, plus normal closing costs on a loan you'll hold for a few months. Short-term dollars for a short-term problem — judge the cost against what you lose by not being able to buy the house, not against a 30-year rate you'll never get on this product.
On qualifying, the big question is whether you have to carry both payments on paper. Some bridge programs let the underwriter exclude the departing residence's payment from your debt-to-income ratio once the bridge is in place, or once your old home is in contract. Others make you qualify holding both. That one underwriting difference decides whether the deal works for most people, and it varies lender to lender.
Beyond that, expect what you'd expect: solid credit, verifiable income, meaningful equity in the departing home, and reserves. Bridge lenders are lending against a sale that hasn't happened yet, so they want evidence the house will actually move — a realistic price, a real agent, a market that supports it.
- Higher rate than a permanent mortgage, plus points and standard closing costs
- Often interest-only, sometimes fully deferred until the sale funds
- Whether the old payment counts in your DTI varies by lender — ask this question first
- Real equity in the departing home is the gate, not just a high sale price
- Reserves and a credible listing plan matter to the underwriter
How do I pick the right route?
Start with the calendar, because it eliminates most of the choices for you. More than six months out from buying? Open a HELOC now, before you list — you may never need a bridge at all. Under sixty days and already writing offers? That window has closed and you're deciding between a bridge and selling first.
Then look at your debt ratio. If you comfortably qualify carrying both houses, optimize purely on cost. If you don't, you need a lender that will exclude the departing payment, and that narrows the field to specific programs. One conversation and a look at your income settles it.
Last, be honest about the departing house. A well-priced three-bedroom in Santa Rosa and a custom hillside property in Kenwood do not sell on the same timeline, and a bridge sized to a 60-day sale is a stressful thing to hold at month nine. Plan around the slower of two honest scenarios and be pleasantly surprised.
Where this goes sideways — and how we avoid it
The failure mode is almost always the same: the old house doesn't sell at the number everyone assumed. The bridge was sized on an optimistic list price, the property sits, and now you're cutting the price on a house that has to pay off a loan on a deadline. That's a bad place to negotiate from.
So we underwrite the exit before we fund the entrance. What's the realistic price, what does the pending data actually say, and what happens if it sells for less? If a 10% haircut breaks the plan, the plan is too thin and we change the structure — a smaller bridge, less house on the buy side, or selling first. Being disciplined up front is cheaper than being wrong in month seven.
The other one I watch for is timing the two closings. Simultaneous is ideal and rarely happens. Build in a few days of slack, keep a rent-back live on the sale side, and order the bridge payoff demand early so nobody's chasing a wire on the last afternoon.
Why run this through a broker instead of your bank?
Bridge loans are not a commodity. One lender excludes your departing payment from the ratio, the next one doesn't. One caps you at 75% combined LTV, another stretches further. Points, term length, deferred versus interest-only, whether they'll cross-collateralize both properties — every one of those is a different answer at a different shop. Your bank has exactly one version of this product, and if their box doesn't fit your file, their answer is no.
As a brokerage, I put the same scenario in front of multiple lenders and let their terms compete — and just as often I talk a client out of the bridge entirely because the HELOC or the rent-back gets them there for a fraction of the cost. Bring me the two properties and your numbers, and I'll tell you within a day which of these four routes actually fits.
