How to Sell Your Home While Buying Another:
Bridge Loans, Contingencies & Timing Strategy
The three strategies for solving the buy-sell timing problem — with the real costs, risks, and market conditions where each one works best.
The most common logistical problem in residential real estate isn't finding a home or getting a mortgage — it's timing the sale of your existing home with the purchase of your next one. Do it wrong and you either end up paying two mortgages simultaneously, or you sell before you buy and need temporary housing. There's no perfect solution, but there are three strategies — each with a different risk profile, cost structure, and suitability depending on your market and financial position.
The Three Strategies
Bridge Loans: The Full Cost
Bridge loans are widely discussed but rarely explained with full numbers. Here's what one actually costs:
| Bridge Loan Detail | Typical Range |
|---|---|
| Interest rate | Prime + 1.5–2% (typically 8.5–10%+ in 2026) |
| Loan term | 6–12 months (some lenders up to 24 months) |
| Origination fee | 1–3% of loan amount |
| Appraisal and other fees | $500–$1,500 |
| Maximum loan-to-value | 80% of current home's value |
| Monthly cost ($200K bridge at 9%) | $1,500/month interest-only |
| Total cost (6-month bridge) | $9,000–$13,000+ in interest and fees |
The bridge loan makes financial sense when: you have significant equity, your current home is highly saleable (expect to sell in 30–90 days), and the value of staying in one home through the transition exceeds the cost. It makes less sense when your current home could take 3–6 months to sell — the carrying cost compounds rapidly.
If you have an existing HELOC (Home Equity Line of Credit) on your current home, you may be able to draw on it for the down payment on the new home — at a much lower rate than a dedicated bridge loan. HELOCs typically run at Prime + 0.5–1% (8–9% currently) and have no origination fees if already established. Lenders may require the HELOC to be paid off before or at the time you close on the new mortgage, so verify this with your lender before using it as a bridge strategy.
Sale Contingencies: How They Work and When Sellers Accept Them
A home sale contingency in your offer means the purchase is contingent on your current home closing by a specified date. There are two structures:
- Hard sale contingency: The deal is off if your home doesn't close by the date specified. Seller gets their home back. Riskiest for sellers, which is why they resist these.
- Kick-out clause contingency: Seller can continue marketing the home. If another non-contingent offer comes in, you get 72 hours to remove your contingency (and proceed with your own financing) or lose the deal. This is more seller-friendly and dramatically more likely to be accepted.
Offer the kick-out clause proactively. Sellers are much more likely to accept a contingent offer if it includes a kick-out clause — it gives them a safety valve. Propose a 72-hour notice window (not 48 hours — too short for most buyers to arrange bridge financing in an emergency). Price your offer at or near full ask to compensate the seller for accepting the contingency.
The Simultaneous Close — Coordinating Both on the Same Day
A third path is coordinating the sale of your current home and the purchase of your next home to close on the same day. Your sale proceeds fund your new home's down payment — no bridge loan, no temporary housing, no gap. This is the cleanest solution when it works. When it doesn't, it's a very expensive disaster.
What breaks simultaneous closes
- Your buyer's lender has a last-minute underwriting issue
- Title issue discovered during final title search on either property
- Your current home doesn't appraise at contract price
- Your buyer's walk-through reveals a new issue requiring negotiation
- Wire transfer timing issues (lenders fund in the afternoon; same-day recording deadlines)
Even if you plan a simultaneous close, pre-arrange bridge financing or a HELOC drawdown before closing day. If something breaks in your sale at 11am on closing day, you need an alternative by 2pm. The bridge you pre-arranged but don't need costs you nothing. The bridge you can't get in four hours costs you the deal.
The Bottom Line
The best strategy depends on your equity position, your local market, your timeline flexibility, and your risk tolerance. Sell-first minimizes financial risk at the cost of logistics. Buy-first with a bridge minimizes disruption at significant cost. A well-structured contingency works when you find a seller willing to accept it. The simultaneous close works beautifully when it works — and requires a backup plan for when it doesn't.
