TL;DR:
If your down payment is locked in a home that hasn't closed, there are a handful of ways to reach it early — a bridge loan, a home equity line opened before you list, borrowing against investments or a retirement plan, or a gift or private loan from family. Each carries a cost, and the differences are mostly about timing and qualification rather than the headline rate. The one that catches people is the home equity line: most lenders won't open one on a house that's already on the market, so that decision has to be made before the sign goes up.
The Problem, Briefly
Most sellers buying another home need the proceeds from the first to fund the second, and the two closings rarely line up on their own. That's why selling first is the default recommendation for most households — the discussion of whether to sell or buy first covers why, along with the cost of carrying two homes if you buy first anyway.
This post assumes you've decided to buy before your sale closes, or that circumstances have decided for you, and covers how the money gets there.
Before comparing options, get a realistic net proceeds figure for the home you're selling, since every option below is sized against it. The breakdown of what a Long Island sale costs covers each deduction.
A Home Equity Line, If You Move Early Enough
A home equity line of credit borrows against the equity in your current home, and you draw only what you need. It's generally the least expensive of the options here.
The catch is timing, and it's the single most useful thing to know on this page: most lenders won't open a home equity line on a property that's listed for sale. Some won't proceed once a listing agreement is signed, others once it's on the market. Either way, if you think you might want one, apply well before listing — once the sign goes up, the option usually closes.
Two other considerations. Your lender will include the payment when calculating what you qualify for on the new mortgage, so opening a line can reduce your purchase budget. And the balance has to be paid off when your current home sells, which comes out of the proceeds.
A Bridge Loan
A bridge loan is short-term financing secured by your current home, designed exactly for this gap. You borrow against its equity, use the funds for the down payment, and repay the loan when the home sells.
It's more expensive than a home equity line — higher rates, plus origination and closing costs on a loan you'll hold for a matter of months — and qualification is stricter, since lenders typically want to see that you could carry both mortgages plus the bridge if the sale takes longer than planned. Not all lenders offer them, and terms vary considerably.
The real risk is duration. A bridge loan priced around a two- or three-month sale becomes expensive at six, and the pressure it creates on your asking price is a cost that doesn't appear in the rate. Ask any lender what happens if the sale takes twice as long as expected, and price the option on that basis rather than the best case.
Borrowing Against Investments or Retirement
Two possibilities that sometimes cost less than either of the above, depending on circumstances.
A securities-based line of credit borrows against a taxable investment account without selling the holdings, which avoids triggering capital gains. Rates are often competitive. The risk is specific: if the market falls, the lender can require you to add collateral or repay on short notice, potentially at the worst moment.
A loan from an employer retirement plan is sometimes available, with limits set by the plan, and it's repaid with interest to yourself. But repayment terms can accelerate if you leave the job, and a distribution rather than a loan carries tax consequences and possible penalties. This is firmly a conversation for a CPA and a financial advisor before anything is withdrawn.
Family Help, Done Properly
A gift or loan from family is common and works, provided the paperwork matches the reality.
If it's a gift, mortgage lenders generally require a signed gift letter confirming no repayment is expected, along with documentation of the transfer. If money is actually being lent and the letter says otherwise, that's a problem — and an undisclosed loan affects your debt-to-income ratio.
If it's a genuine loan, it should be documented, and if it's secured against property it needs to be visible to your lender. Family arrangements around real estate also raise tax and estate questions worth a CPA's view, particularly where larger sums or an interest in property are involved.
What Your Lender Needs to Know
Whichever route you take, tell your mortgage lender early. They'll count your existing mortgage payment against what you qualify for until the current home is under a signed contract, and some want to see that contract before committing. They'll also want to trace the source of your down payment, which means any bridge loan, credit line, or family gift has to be documented.
Undisclosed borrowing found during underwriting is a genuine problem, not a technicality — it can delay or derail a commitment late in the process. The post on buying and selling at the same time covers how lenders treat two homes and how the closings are sequenced.
The Options That Don't Require Borrowing
Worth mentioning because they're often cheaper than any of the above.
A longer closing on your sale, or a short period of possession after closing negotiated by the attorneys, can shrink the gap enough that no financing is needed. A purchase contingent on your sale avoids borrowing entirely, though it weakens the offer. And selling first, with interim housing, remains the least expensive path for many households once the borrowing costs are actually compared. The mistakes checklist covers the timing errors that make financing necessary when it needn't be.
A Worked Example
Consider a composite case — a Nassau County couple who found the home they wanted before listing their own.
They had planned on a home equity line and discovered, when they applied, that their lender wouldn't open one with a listing agreement signed. That left a bridge loan, which their lender quoted at a meaningfully higher rate plus origination costs, and which required them to show they could carry both mortgages plus the bridge.
They qualified, but ran the numbers on a six-month sale rather than a three-month one and didn't like the figure. Instead they made their offer contingent on their sale, which the seller accepted because the home had been listed a while.
Had they applied for the equity line two months earlier, before the listing agreement, they'd have had a cheaper option and a stronger offer.
Where to Start
Talk to a lender or mortgage broker before listing, not after, and ask specifically what's available to you and what timing each option requires. Get a realistic net proceeds figure so you know how much you actually need to bridge. Price every option on a slower sale than you expect. Make sure your lender knows about any borrowing or gift, and that the paperwork matches the reality. And compare all of it against simply selling first, which is often cheaper than it looks. For a starting read on value, try a quiet look at current figures.
The Honest Bottom Line
Every way of reaching your equity before the sale closes costs something — interest, fees, market risk, or a weaker offer. The right one depends on your finances and how long the sale realistically takes.
What's worth acting on now is the timing. The cheapest option, a home equity line, usually has to be arranged before the home is listed, and people find that out too late. If there's any chance you'll buy before you sell, have that conversation with a lender early. For anyone working through a specific move, with no pressure attached, that conversation is available whenever the timing suits.
This is general information, not lending, tax, or financial advice. Loan products, rates, and qualification requirements vary by lender and change. Consult a lender or mortgage broker, a CPA, and a licensed New York real estate attorney about your circumstances.
FAQs
Can I get a home equity line after listing my home?
Usually not. Most lenders won't open one on a property that's on the market, and some stop once a listing agreement is signed. If there's any chance you'll want one, apply well before listing. Keep in mind that the payment counts against what you qualify for on your new mortgage, and the balance is repaid from your sale proceeds.
What's the difference between a bridge loan and a home equity line?
A bridge loan is short-term financing designed specifically for the gap between buying and selling, secured by your current home and repaid when it sells. A home equity line is a revolving credit line you draw on as needed. The line is generally cheaper but has to be opened before listing; the bridge loan can be arranged later but costs more and has stricter qualification, since lenders want to see you could carry both mortgages plus the bridge.
How risky is a bridge loan if my home takes longer to sell?
That's the main risk. A bridge loan priced around a two- or three-month sale gets expensive at six, and carrying it puts pressure on your asking price — a cost that doesn't show up in the rate. Ask any lender what happens if the sale takes twice as long as expected, and evaluate the option on that basis rather than the best case.
Can I use a gift from family for my down payment?
Yes, and the paperwork has to match the reality. Lenders generally require a signed gift letter confirming no repayment is expected, plus documentation of the transfer. If money is actually being lent, saying otherwise is a problem, and an undisclosed loan affects your debt-to-income ratio. Larger family arrangements around property also raise tax and estate questions worth a CPA's view.
Do I have to tell my lender how I'm funding the down payment?
Yes. Lenders trace the source of down payment funds, so any bridge loan, credit line, or gift has to be documented. Undisclosed borrowing found during underwriting can delay or derail a commitment late in the process. Tell your lender early — they'll also explain how your existing mortgage affects what you qualify for before your current home is under contract.
