Should you buy now or wait? The 2026 rate lock-in effect.

For three years, the Seattle-Bellevue market was partly frozen by the rate lock-in effect. Homeowners with 2.75–3.5% mortgages refused to sell and trade into a 7% payment. That reluctance suppressed inventory and kept competition fierce even as rates rose.

As of May 2026, rates have stabilized in the low-to-mid 6s and the psychology is shifting. Sellers who delayed life moves — upsizing, downsizing, relocating — are starting to move. That means more real inventory, more comparison points, and more negotiating room than buyers have had in years.

Many buyers are sitting on the sidelines waiting for rates to return to 4%. Here is the problem with that plan: if rates drop sharply to 4%, every buyer who has been waiting will enter the market at the same time. That sidelined demand is likely to ignite bidding wars and push Eastside home prices up by 10–15% or more in a short window.

The math most waiting buyers do not run: a 10% price increase on a $1.2M Eastside home adds $120,000 to the purchase price. At 4%, the monthly payment on that higher-priced home can easily exceed what you would pay today at 6.3% on the original price — plus you lose the option to refinance down from today's rate.

The 2026 strategy many RexMont clients are using: buy the home now with 60% more Eastside inventory to choose from, more seller concession room, and a rate you can refinance later. You can change your rate. You cannot change your purchase price.

As of May 2026, active listings across the Eastside are up significantly compared to a year ago. For buyers, that shift changes the negotiating dynamic in meaningful ways.

In 2023 and 2024, buyers routinely waived inspections, escalated well over asking, and accepted homes as-is just to compete. In May 2026, sellers in most price bands are now entertaining inspection credits, repair requests, and seller-paid rate buydowns — concessions that were essentially unavailable two years ago.

A seller-paid 2-1 buydown, for example, can give a buyer a 4.3–4.4% effective rate in year one and a 5.3–5.4% rate in year two, before settling at the note rate. On a $1.5M purchase, that first-year difference can reduce the monthly payment by $1,500 or more. Getting a seller to cover that cost in today's market is realistic in a way it simply was not in 2022.

More inventory does not mean every home is a patient negotiation. In top school districts — Bellevue, Issaquah, Lake Washington — and on premium lots with lake or mountain views, well-priced homes still attract multiple offers within days.

The buyers winning those situations are pre-underwritten (not just pre-approved), have a clear escalation plan, and work with an agent who knows which contingencies matter in each neighborhood and which create unnecessary friction. Speed and preparation still matter where demand is concentrated.

Before answering the timing question, RexMont agents walk buyers through three comparisons: the payment at today's rate, the payment with a seller-paid buydown negotiated at close, and the projected payment if rates drop to 4% but prices rise 10–12% in response.

If the home fits a five-year plan, is in a supply-constrained neighborhood, and the numbers work at today's rate, waiting is a gamble on inventory that will not stay this favorable. If the home has been sitting, has visible deferred maintenance, or is in a segment with ample comparable supply, there is room to negotiate harder — or wait for a better listing.

The answer is different for every buyer and every property. What it is not is a simple function of where rates are this week.
