This is the call I get more than any other from people who already own a house in Delco. They've outgrown the twin in Ridley or the Cape in Drexel Hill, they've found the next place, and they're stuck on the order of operations. Sell first and you might be homeless for a month. Buy first and you might be paying two mortgages until spring. Most people assume those are the only two choices.
They aren't. There are about six ways to structure this, and the right one depends on three things: how much equity you have, what your income can carry, and how fast your current house is likely to sell. I spent 20+ years on the mortgage side before I became an agent, so here's how I walk clients through it.
First, why this is harder right now
For most of 2021 through 2024, this wasn't much of a puzzle. You listed on Thursday, had offers by Monday, and negotiated a long settlement or a rent-back so you could close on the next house. The sale was the easy part.
That's changing. Rates are back above 7% (Freddie Mac's 30 year average was 7.40% the week of October 15), and Delco is drifting toward a slightly buyer-leaning market. That cuts both ways for a move-up buyer. You have more leverage on the house you're buying, but your own house may sit longer than your neighbor's did two years ago. Any plan that assumes your house sells in a weekend needs a backup now.
Option 1: Sell first, then buy, with a soft landing
The safest path financially is still selling first. You know exactly how much cash you have, you only qualify for one mortgage, and nobody's carrying two houses. The problem is timing, and there are two tools for that.
The first is a longer settlement date on your sale. Sixty or even ninety days gives you room to find and close on the next house. In a slower market a buyer may push back on that, but plenty of buyers have their own lease to run out and are happy with it.
The second is a post-settlement possession agreement, which most people call a rent-back. You settle on your sale, get your money, and stay in the house for a set period while you close on the next one. Your agent and your buyer's agent write it up as part of the deal, usually with a daily or monthly rate and an escrow held back to cover any damage. Some buyers' lenders limit how long a rent-back can run, so get that answer early.
The downside is that you're shopping on a deadline, and deadlines make people buy the wrong house. If the right house isn't on the market when you need it, you're looking at a short-term rental and two moves.
Option 2: Buy with a home sale contingency
A sale contingency means your purchase depends on your current house selling by a certain date. If it doesn't, you can walk away and keep your deposit. Two years ago a seller would have laughed at that offer. Today, with fewer buyers in some price ranges, sellers are more willing to take one, especially if your house is already listed or under contract.
The key here is how strong your contingency looks. "I'll list it soon" is weak. "My house is under agreement and settles in 45 days" is almost as good as cash. Sellers usually protect themselves with a kick-out clause: they keep marketing their house, and if another acceptable offer comes in, you get a set number of days to drop the contingency or step aside.
This works best when your house is priced right and the house you want has been sitting for a few weeks. It works worst in the towns where good houses still draw multiple offers, because a contingent offer usually loses to a clean one there.
Option 3: Open a HELOC before you list
This is the one I wish more people knew about, and the timing matters more than anything else. A home equity line of credit on your current house can give you the down payment for the next one without waiting for your sale. You buy the new place, move, sell the old one, and the HELOC gets paid off at settlement.
Here's the catch: most lenders won't open a HELOC on a house that's already listed for sale. So if this is your plan, it has to happen before the sign goes in the yard. Applying and closing on a HELOC takes a few weeks, so start there, then list.
A HELOC is usually variable rate, and the rate is typically higher than a first mortgage. But if it's only open for a few months, the interest cost is usually modest compared with the alternative of moving twice. It also won't touch your existing first mortgage, which matters if that rate starts with a 3.
Option 4: A bridge loan
A bridge loan does the same job as a HELOC, but it's built for exactly this situation. It's a short-term loan, often six to twelve months, secured by your current house, and it's designed to be paid off when that house sells. Some versions pay off your existing mortgage and roll it into the bridge so you only have one payment on the old house.
The honest truth about bridge loans: they cost more. Expect a higher rate than a regular mortgage and upfront fees, and fewer lenders offer them than people think. They make the most sense when you have a lot of equity, a house that will clearly sell, and a reason a HELOC won't work (you've already listed, for example, or you need more than a HELOC lender will give you).
Option 5: Buy first and carry both for a while
If your income can qualify for both payments at once, you can simply buy the new house with a regular mortgage, move, and sell the old one empty. Empty houses are easier to show, easier to stage, and easier to fix up between owners, so this isn't the worst problem to have.
The question is qualifying. A lender will count your current mortgage payment against you unless your old house is under contract or rented out, and the rules on when they can leave it out vary by loan program. This is the part people get wrong on their own. Ask the lender exactly how they'll treat your current house before you write an offer, not after.
One more piece I like here is a mortgage recast. You buy the new house with a bigger loan and a smaller down payment, then when the old house sells you put the proceeds toward the principal, and the lender re-figures your payment on the lower balance. You keep the same rate and term and get a lower monthly payment. Many conventional loans allow it for a small fee. FHA and VA loans generally don't, so check before you count on it.
Option 6: Cash-out refinance (not right now, though)
You'll see this on every list of options, and in 2021 it was a good one. Today, if you have a mortgage from the low rate years, refinancing it at 7% just to pull cash out for a few months makes very little sense. You'd pay closing costs on a new loan you plan to pay off right away. There are exceptions, like a house that's paid off or nearly so, but for most Delco homeowners a HELOC or bridge loan does the same job for less.
How I'd decide
When someone sits down with me with this question, I'm really asking three things.
How much equity do you have? If it's a lot, the HELOC, bridge loan, and recast options are all open. If it's thin, you're almost certainly selling first.
Can your income carry both houses for a few months? If yes, buying first gets much easier and much less stressful. If no, you need your sale to happen first or at the same time.
How fast will your house really sell? This is where local knowledge matters. A well-kept house in a busy school district is a different bet from a house that needs work in a town where listings are sitting. I'll pull the recent sales and tell you honestly which one you've got.
One Delco-specific wrinkle: many of our municipalities require a resale use and occupancy inspection before settlement, and if it turns up repairs, it can slow your sale down. If your timeline is tight, schedule that inspection early so a surprise on the old house doesn't hold up the new one.
A word on lenders
I don't offer or arrange loans, and I don't have a lender I steer people to. What I do is help you figure out which of these structures fits, then give you the right questions to ask. Talk to two or three lenders, tell each one exactly what you're trying to do, and compare their Loan Estimates side by side. Not every lender offers HELOCs on a soon-to-be-listed house, bridge loans, or recasts, so asking upfront saves you weeks.
If you're weighing whether to move at all, my guide on keeping your low rate or selling runs the break-even math, and refinance, renovate, or move compares staying put with moving. For where rates stand this month and what they do to a payment, see my Delaware County mortgage rates guide.
