What should you do if you bought a new home and your old one hasn’t sold?
Start by fixing what’s in your control: price, condition, and presentation — a home that’s priced and presented right almost always sells in a balanced market. Then calculate your true monthly carrying cost and set a deadline. If the home still isn’t moving, your main options are a price adjustment, renting it out, bridge or HELOC financing to cover the gap, or a mortgage recast on the new home once the old one sells. The worst move is waiting without a plan.
Buying first can be the right call. You move once, you shop without pressure, and you don’t need temporary housing.
But it comes with one risk every move-up buyer worries about: you close on the new home, and the old one just sits. Two mortgages, two sets of utilities, two lawns to mow.
If you’re there right now — or you’re trying to plan so you never are — here’s how I’d work through it. For the bigger picture on equity and sequencing, start with our home equity and move-up planning hub.
Step 1: Know your real carrying cost
Before deciding anything, put a number on what each month of waiting costs you. Here’s an illustrative example — your numbers will differ.
| Monthly cost of the unsold home | Example |
|---|---|
| Mortgage principal and interest | $2,400 |
| Property taxes | $550 |
| Homeowner’s insurance (vacant-home coverage may cost more) | $150 |
| Utilities and lawn care | $350 |
| HOA dues, if any | $0–$100 |
| Total | About $3,450–$3,550/month |
Now compare that with a price reduction. If dropping the price by $10,000 helps you sell two months sooner, you’ve roughly broken even on carrying costs — and removed the stress and risk.
Vacant homes also need attention. Tell your insurance company the home is vacant. Many standard policies limit coverage after a set number of days unoccupied, so ask about a vacancy endorsement.
Step 2: Diagnose why it isn’t selling
Homes don’t sell for a short list of reasons:
- Price — the most common reason by far
- Condition — deferred maintenance, dated finishes, or inspection surprises
- Presentation — dark or empty rooms, weak photos, or a home that’s hard to show
- Marketing reach — buyers simply aren’t seeing it
- Terms — no flexibility on closing date or credits in a market where buyers expect some
Look at your showing count and feedback. Lots of showings and no offers usually means price or condition. Few showings usually means price or online presentation. Here’s our full checklist for why a house isn’t selling in Pierce County.
A vacant home often shows worse than an occupied one. Light staging — even a few key rooms — can help buyers understand scale and layout.
Step 3: Choose your path
Option A: Adjust the price or offer a credit
In today’s market, a well-placed concession can work as well as a price cut. A credit toward a buyer’s rate buydown can lower their monthly payment more than an equal price reduction. Set a date — for example, two to three weeks out — to adjust if activity doesn’t improve.
Option B: Rent it out
Renting can cover most or all of your carrying cost while you wait for better conditions. But it’s a real business decision:
- You become a landlord, with Washington landlord-tenant obligations
- Selling a tenant-occupied home later is harder
- Capital gains treatment can change if the home stops being your primary residence for too long — talk to a tax adviser
Our guide to selling or renting out your home when you move up walks through the math.
Option C: Use a bridge loan or HELOC to cover the gap
If you opened a HELOC on your old home before buying, it can cover payments for a few months. Bridge loans can also cover the gap, at a higher cost. These buy time — they don’t fix a pricing problem. Here are the bridge loan and HELOC questions to ask your lender.
Option D: Plan a recast for when it sells
If you put a smaller down payment on the new home to buy first, many lenders allow a mortgage recast — you pay a lump sum toward principal after your old home sells, and the lender recalculates a lower monthly payment while keeping your rate. Recasts are common on conventional loans but generally aren’t available on FHA or VA loans. Fees and minimums vary, so ask your lender before you close.
How to keep this from happening
The best way to handle an unsold home is to plan for it before you buy:
- Price the current home realistically before you write an offer on the next one.
- Get the old home listing-ready first — repairs, cleaning, and photos done.
- Stress-test your budget. Could you carry both homes for three to six months?
- Line up your financing — a HELOC opened before listing, or a bridge loan quote.
- Consider a buy-before-you-sell program if you need certainty. Some include a guaranteed backup offer. Here’s how buy-before-you-sell programs work in Washington.
Lenders treat your current mortgage differently depending on the loan program. Some may count projected rental income from your departing home to help you qualify, usually at a discounted percentage and with added reserves. Ask your lender exactly how your current home will be counted before you shop.
Frequently Asked Questions
What happens if I buy a house and can’t sell my old one?
You’ll carry both homes until it sells, rents, or you refinance. Most homeowners solve it by adjusting price or terms, renting the home out, or using a HELOC or bridge loan to cover payments while they sell.
How long can I afford to carry two mortgages?
Add up the full monthly cost of the old home — mortgage, taxes, insurance, utilities, and upkeep — and compare it with your savings and income. Set a firm deadline for adjusting price so carrying costs don’t quietly outgrow the price reduction you were avoiding.
Should I lower the price or rent out my house?
Lowering the price usually makes sense if you need your equity for the new home or don’t want to be a landlord. Renting can work if the rent covers your costs and you’re comfortable managing tenants. Talk to a tax adviser about capital gains before renting long-term.
What is a mortgage recast?
A recast lets you pay a lump sum toward your mortgage principal, after which the lender lowers your monthly payment while keeping your interest rate and term. It’s common on conventional loans, but FHA and VA loans generally can’t be recast.
Does a vacant house sell slower?
It can. Empty rooms can feel smaller and show flaws more easily. Light staging, good lighting, and regular maintenance help a vacant home show its best.
Carrying two homes is a plan problem, not a panic problem
If your old home hasn’t sold, you have options. The key is knowing your monthly cost, fixing what buyers are reacting to, and choosing a path with a deadline.
