Why It Affected Mortgage Rates

The chain of events is worth understanding, because it helps explain why rates moved so quickly. Iran retaliated to the strikes by effectively blocking the Strait of Hormuz, one of the world’s busiest oil-shipping channels, sending energy prices soaring. Rising oil prices fueled inflation fears. Inflation fears caused bond investors to sell, pushing Treasury yields higher. And since mortgage rates closely follow the 10-year Treasury yield, 30-year fixed mortgage rates rose from around 6% to approximately 6.4% throughout March — their highest level in seven months.

The day before the strikes began, the average rate on a 30-year fixed loan was 5.99%. That brief window below 6% is now closed, at least for now.

What It Means for Seattle Specifically

The Seattle market has felt the impact, but it hasn’t fallen apart. King County’s closed and pending sales for single-family homes dropped around 3% and 4% respectively from a year ago, and some price softening has appeared in certain segments. But demand hasn’t collapsed — it’s become more selective.

Seattle buyers are getting choosier. Tolerance for road noise, poor floor plans, and outdated kitchens has dropped, because buyers feel that if they’re going to pay top dollar and carry what they perceive as a high rate, they want the best available. That’s not a market in crisis — that’s a market finding its footing.

Importantly, there is still significant cash activity in Seattle, and people are still buying homes. The buyers most affected are those earlier in their careers without large cash reserves — not the broader pool of Seattle buyers.

The Case for Keeping Your Plans

Here’s the part worth holding onto: even at 6.4%, Seattle buyers are in a materially better position than they were a year ago.

Mortgage interest rates dropped below 6% on February 26 — a four-year low — before the conflict pushed them back up. But despite the reversal, buyers today still have roughly $30,000 more in buying power compared to a year ago, thanks to the combination of moderating prices and rates that remain below their 2023 peak of nearly 8%.

And the inventory story hasn’t changed. Seattle added 1,548 new listings in April, up nearly 20% year over year, while total homes for sale climbed 30%. More supply means more options, less competition, and more room to negotiate — none of which disappears because rates ticked up half a point.

The Real Cost of Waiting

Waiting for rates to fall back below 6% is a tempting strategy — but it carries its own risks.

Both Fannie Mae and the Mortgage Bankers Association forecast rates potentially drifting back toward 5.75%–6% later in 2026. That’s possible. But trying to time the perfect mortgage rate is a losing game because the variables that move rates — like geopolitics, Federal Reserve policy, inflation, and global capital flows — are genuinely unpredictable, and the cost of waiting is not zero.

While you wait, you’re paying rent. Spring inventory — currently at its highest level in years — may thin out by fall. And if rates do drop, the buyers who’ve been sitting on the sidelines will flood back in, increasing competition and potentially pushing prices up. The window of low-pressure shopping you have right now may not survive a rate drop.

Your Practical Plan for Right Now

Get rate-smart, not rate-obsessed. Focus on your monthly payment, not the rate number. At 6.4% vs. 5.99%, the difference on an $800,000 loan is roughly $220/month — meaningful, but not a dealbreaker for most Seattle households. Model your payment at current rates and decide if the home makes sense at that number.

Use the selectivity to your advantage. Buyers who used to look at 10–15 houses are now touring 25–30. That’s actually healthy. Use this moment to get clear on exactly what you want — and when the right home appears, be ready to move.

Target the condo market. The condo segment is the softest spot in Seattle right now. Seattle condo median prices are down 6% year over year to $596,000, and only 25% of listed condos sold in the first 10 days. For buyers with flexibility on property type, there is genuine negotiating leverage here.

Ask about rate buydowns. With sellers facing longer days on market, many — especially in new construction — are willing to offer concessions. A seller-paid rate buydown can effectively get you a below-market rate without waiting for broader rates to fall.

Keep perspective on the big picture. If the current conflict scenario ends before July, home sales nationally are still projected to rise compared to last year. Seattle’s underlying fundamentals — strong employment, geographic supply constraints, and a high-income workforce — haven’t changed. Geopolitical disruptions create noise; they rarely alter the long-term trajectory of a market this structurally sound.

The Bottom Line

The Iran war introduced real uncertainty into a housing market that was just starting to find its stride. Rates are higher than they were in February, buyer confidence has dipped, and some hesitation is completely rational.

But Seattle remains a resilient market, and the conditions that favor buyers — more inventory, more negotiating room, motivated sellers — are still in place. The buyers who will look back on spring 2026 most favorably won’t be the ones who timed rates perfectly. They’ll be the ones who stayed focused, stayed prepared, and moved when the right home appeared.
