Mercer Island is a small island city in Lake Washington between Seattle and Bellevue, with I-90 running through its north end. Inventory is limited because the island can’t grow outward. Many island moves are within the island: a longtime owner moving to a Town Center condo, or a household moving from the north end to a waterfront or view home. When the home you want only comes up occasionally, the timing of your own sale matters a lot.

The Mercer Island Market Snapshot
With a small number of sales each month, Mercer Island statistics can change a lot from month to month. Look at several months together and separate waterfront, view and standard homes:
- Median sale price: [LOCAL STAT: median sale price, Mercer Island, source NWMLS]
- Median days on market: [LOCAL STAT: median days on market, Mercer Island, source NWMLS]
- Months of supply: [LOCAL STAT: months of supply, Mercer Island, source NWMLS]
- Sale-to-list price ratio: [LOCAL STAT: percent of list price received, Mercer Island, source NWMLS]
- Number of closed sales, trailing 12 months: [LOCAL STAT: closed sales trailing 12 months, Mercer Island, source NWMLS]
- Waterfront sales, trailing 12 months: [LOCAL STAT: waterfront closed sales trailing 12 months, Mercer Island, source NWMLS]
A small number of sales means one unusual sale can shift the median. We’ll look at the specific comparable sales for your home rather than relying on a single headline number.
How to Buy and Sell at the Same Time on Mercer Island
When the right home appears, be ready
Because island inventory is limited, the home you want may come up with little warning. The best preparation is having your current home ready to list, knowing your financing options in advance, and deciding before you start looking how much overlap you can handle.
The three main strategies
Buy first. This is common on Mercer Island because the next home can be hard to find. Bridge loans, HELOCs and buy-before-you-sell programs can make a clean offer possible. Terms, fees and qualifications vary, and high-value or waterfront properties may have different lending rules. Talk to lenders directly and early.
Sell first with a rent-back. You sell, lock in your price, stay in the home for an agreed time under NWMLS Form 65B, and look for your next home with cash in hand. This fits well for downsizers moving to a condo, or for anyone whose next home isn’t limited to the island.
Contingent offer. A sale contingency (NWMLS Form 22B) is harder to use on sought-after island homes, but it can work in some cases, especially when your home is already under contract.
Waterfront and view-home details
- Shoreline structures. Docks, bulkheads and boat lifts may need inspection by a specialist and can be subject to state, federal and city permitting rules. Know what permits exist.
- Shared access and easements. Some island homes share driveways, lake access or view easements. Read those documents early.
- Slopes and drainage. Hillside homes may need extra inspection time for drainage and retaining walls.
- Appraisals. Unique waterfront and view homes can take longer to appraise because comparables are limited. Allow time for this in both contracts.
Off-island buyers and sellers
Some island owners move to Bellevue, Seattle or elsewhere in the greater Seattle area, and some off-island buyers want to move to the island. In either case, the data for both markets affects which home should be sold first.

Mercer Island FAQ
There’s so little inventory. Should I sell before I find my next home?
It depends on whether your next home needs to be on the island. If it does, buying first is often considered. If you’re open to other areas, selling first with a rent-back may be simpler.
Can I sell my home quietly, without a public listing?
There are options for more limited marketing, but they can reduce exposure and may affect the price. NWMLS has rules about how and when listings must be shared. We’ll go over the tradeoffs before you decide.
Is waterfront harder to finance?
Some high-value or waterfront properties have different lending requirements. A lender can explain what applies to your situation.
How long does a rent-back usually last?
It’s negotiated, and the buyer’s lender may have limits. We’ll set the length based on your timing and what the buyer can accept.
I’ve owned my home for decades. Should I worry about taxes when I sell?
That’s a question for a CPA or tax advisor. Get their advice before we set the timing, because it can affect your plan.
