Yes, you can buy and sell a home at the same time in Seattle. Most people use one of five ideas: sell first, buy first, make a contingent offer, use financing that lets you buy before you sell, or sell and rent back. Which one fits comes down to where your next down payment comes from, so the right answer starts with a short talk with your agent and your lender.
Idea finder
Which ideas fit your move?
I’ve helped a lot of Seattle owners move from one home to the next. The ones who sleep well picked their idea before they fell in love with a house. Start with the finder, then read the idea it puts on top.
The challenge
Why buying and selling in Seattle at the same time feels hard
Two deals, one family, and three questions that pull against each other: money (most people need the sale to pay for the next home), timing (the right house rarely shows up on your schedule) and where you live in between.
None of the five ideas below solves all three. Each one trades a little of one for more of another. That’s why the first move is a conversation, not an offer.
The five ideas
Five ideas for buying and selling a home at the same time
Here they are in plain words. Each one ends the same way, because your agent and lender are the two people who can tell you whether it works with your numbers.
Sell first, then buy
What it is. You sell your current home, then shop with the sale money in hand.
It suits you when you need the sale money for the next down payment, and one payment at a time matters more than speed.
The trade-off. You may need somewhere to live in between, and possibly two moves.
Talk with your agent and lender. Ask your agent how long homes like yours are taking to sell. Ask your lender what you can buy with your expected sale proceeds.
Buy first, then sell
What it is. You buy the next home with savings or other funds, move once, then sell the old home empty.
It suits you when your down payment doesn’t depend on the sale, and you could carry two housing payments for a while.
The trade-off. Two payments until the old home closes, and the pressure of a home that hasn’t sold yet.
Talk with your agent and lender. Ask your lender whether you qualify with both payments. Ask your agent what the empty home needs before it lists.
Make an offer contingent on selling your home
What it is. Your offer says you’ll buy once your current home sells. In Washington this is written on an NWMLS addendum, Form 22B.
It suits you when you need the sale money, want to pick the next home first, and the market you’re buying in has room to wait.
The trade-off. Many sellers prefer offers that don’t depend on another sale, and the seller can keep the home on the market while you sell yours.
Talk with your agent and lender. Ask your agent how contingent offers are doing in the neighborhoods you like. Ask your lender to confirm you qualify once your home sells.
Use financing that lets you buy before you sell
What it is. A loan or program uses the equity in your current home so you can buy first: a bridge loan, a home equity line of credit, or a buy-before-you-sell program from a lender or company.
It suits you when you have solid equity, steady income, and want the next offer to stand on its own.
The trade-off. It costs more than a regular mortgage, and if the old home is slow to sell, the short-term loan still comes due.
Talk with your agent and lender. Ask your lender which of these they offer, what they cost and how the payments count toward qualifying. Ask your agent how fast homes like yours are selling.
Sell, then rent back for a short time
What it is. You sell, and the buyer lets you stay in the home for a short, agreed stretch after closing, under a written rental agreement.
It suits you when you want the sale money first but would rather not move twice or rent somewhere else.
The trade-off. The buyer has to agree, and you live as a tenant in the home you sold, on their schedule.
Talk with your agent and lender. Ask your agent how a rent-back fits the buyers you’re likely to see. Ask your lender and insurance agent how it affects the buyer’s loan and policy.
Side by side
Buy before you sell, or sell first? The five ideas side by side
| Idea | Best when | Next down payment from | The trade-off |
|---|---|---|---|
| Sell first | A sure budget matters most | The sale | A gap between homes |
| Buy first | You can carry two payments | Savings or other funds | Two payments for a while |
| Contingent offer | The market has room to wait | The sale | A weaker offer in a busy market |
| Buy-before-you-sell financing | You have solid equity | A loan against your current home | Extra cost and a deadline |
| Rent-back | You want one move after selling | The sale | Living on the buyer’s schedule |

The gap
Where to live in between, if there is a gap
- Furnished mid-term rentals.One- to six-month stays cost more than a regular lease, often well above normal rent. Search shorter stays, then ask the host about a monthly rate.
- Family or friends.The cheapest bridge, and often the calmest one for a few weeks.
- Storage for the rest.A storage unit or portable container keeps the next move to the things you’ll actually use.
- Watch for rental scams.Use known platforms. Never send a deposit for a place you or someone you trust hasn’t seen.
Taxes
Do you pay tax when you sell one home and buy another?
Buying the next home doesn’t change the tax on the one you sell. Under IRS rules, if you owned and lived in your home for at least two of the last five years, you may be able to exclude up to $250,000 of gain, or $500,000 for a married couple filing jointly.
Every situation is different, and I’m not a tax advisor. Talk with your CPA before you list.

FAQ
Frequently asked questions about buying and selling at the same time
Can I buy a house before selling mine?
Yes, if you can cover the down payment without the sale: savings, other funds, or a loan against the equity in your current home. Your lender confirms whether you qualify with both homes.
Is buying before you sell worth it?
It can be when the numbers work: you move once and your home can go on the market empty and ready. It costs more while you own two homes, so weigh it with your lender first.
How hard is it to buy and sell a house at the same time?
Harder than doing either alone, mostly because of money and timing. Picking one of the five ideas before you shop makes it far more manageable.
What is a contingent offer?
An offer to buy that depends on something happening first. A home sale contingency means you buy only if your current home sells. In Washington it’s written on NWMLS Form 22B.
Should a seller accept a contingent offer?
Sometimes. It can make sense when there are few other offers or the buyer’s home is likely to sell quickly. The seller’s agent can explain the risks for their home.
Can I get a bridge loan before selling my house?
Often, if you have enough equity and income. Bridge loans are short term and usually cost more than a regular mortgage, so ask your lender to compare one with a home equity line of credit.
Can I open a HELOC once my home is listed?
Usually not. Lenders generally won’t open a home equity line of credit on a home that’s already for sale, so ask about it well before you list.
What is a rent-back?
An agreement that lets the seller stay in the home for a short time after closing, as the buyer’s tenant. Both sides sign a written rental agreement.
Do I need two agents to buy and sell?
No. One agent can handle both your sale and your purchase, with a separate agreement for each side.
Can I use my home equity for the next down payment?
Yes. Most people use the money from the sale. Buying first means tapping that equity before the sale, through a loan your lender sets up.
The bottom line
Sell first for a sure budget, buy first to move once, or use a contingent offer, buy-before-you-sell financing or a rent-back to land in between. Pick the idea before you pick the house.
Run it past your agent and your lender with your real numbers. If you’d like a second opinion, I’m a text away.
