Every December, the Seattle forecasts arrive with a confident number for next year's home prices. I am not going to give you one, and the reason is the most useful thing in this article: the single biggest input to the 2027 market is the mortgage rate, and the national forecasters moved their 2027 rate forecast by nearly a full point in one month this October. Any price number built on top of that should come with an asterisk the size of the number.
What I can give you is the picture the forecasts actually support. Rates stay above 7% all year. Sales stay slow. Inventory keeps building. And Seattle prices, after a year of small declines, most likely spend 2027 roughly flat to slightly lower, with the real action in how long homes take to sell and how much sellers give up when they price high.
Where 2026 Leaves Seattle
The latest full month of local data is September 2026, from the NWMLS figures in my September update. Here is where the four areas I track stood going into the last quarter.
| Area | Median (houses) | Year over year | Months of supply (houses) | A year earlier |
|---|---|---|---|---|
| Southeast Seattle | $780,000 | -8% | 2.5 | 2.2 |
| Seattle (all areas) | $960,000 | -2% | 3.0 | 2.1 |
| Eastside | $1,425,000 | -10% | 4.1 | 2.3 |
| King County | $949,975 | -1% | 3.4 | 2.1 |
Two things stand out. Prices fell, but only modestly: Seattle's September median was down 2%, and across the first nine months of the year Southeast Seattle's medians averaged about 5% below 2025. And supply rose everywhere. Seattle had 1,671 houses on the market at the end of September, up 25% from a year earlier, while pending sales were down 10%.
On the scale Windermere uses, under two months of supply is a seller's market, two to four is neutral, and four or more is a buyer's market. Seattle, Southeast Seattle and the county are all inside the neutral band. The Eastside crossed into buyer's territory in September.
That is the starting line for 2027: a neutral market that has been loosening slowly for a year, not one that is breaking.
What the Forecasters Expect for 2027
The national outlook changed sharply in October, and almost entirely because of rates.
Freddie Mac's weekly survey had the 30-year fixed rate at 7.32% on October 22, against 6.19% a year earlier, according to its Primary Mortgage Market Survey. The two forecasts that most of the mortgage industry plans around were both revised up to match.
- 01Fannie Mae's October forecast puts the 30-year rate at 7.4% for the fourth quarter of 2026 and 7.5% in every quarter of 2027, up from 6.7% for 2027 in its September edition, as reported by The MortgagePoint. It also cut its 2027 forecast for existing-home sales nationally to about 4.06 million.
- 02The Mortgage Bankers Association's October forecast is slightly lower: 7.3% for the fourth quarter of 2026, 7.2% for the first three quarters of 2027, and 7.1% by the end of the year. It expects purchase mortgage volume to rise less than 1% in 2027.
- 03Not everyone agrees. Goldman Sachs sees rates easing to about 6.4% by the end of 2027, according to TheStreet.
The honest summary: the central forecasts have rates a little above where they are now for all of 2027, and the most optimistic mainstream view has them back to roughly where they were in the spring of 2026. None of them forecasts a return to the 3% and 4% rates that so many Seattle owners still hold.
What That Rate Does to a Seattle Payment
Rates matter more than prices right now, and the arithmetic shows why. Take Seattle's September median of $960,000, put 20% down, and borrow $768,000 on a 30-year fixed loan. Principal and interest alone, before taxes and insurance:
| Rate | Monthly principal and interest | What it represents |
|---|---|---|
| 6.19% | $4,699 | Freddie Mac's average a year ago |
| 6.40% | $4,804 | Goldman's end-of-2027 view |
| 6.86% | $5,038 | September 2026 average in Windermere's report |
| 7.32% | $5,276 | Freddie Mac's average on October 22 |
| 7.50% | $5,370 | Fannie Mae's 2027 forecast |
The gap between last October's rate and this October's is $577 a month, or about $6,900 a year, on the same house. Put another way, to match the payment a buyer had at 6.19%, a buyer at 7.32% would need the price to fall to roughly $855,000, about 11% below September's median. Seattle prices are not falling anywhere near that fast.
These figures use my own simple assumptions, so they will not match the payment numbers in my monthly updates, which come from Windermere's reports and are built slightly differently. The comparison between rows is the point, not the exact dollars.
My Read on Seattle Prices in 2027
If rates do what the central forecasts say, I expect Seattle's median house price in 2027 to finish within a few percent of where 2026 ends, more likely a little below than above. Three things in the data push me there.
Supply is rising faster than sales. Inventory up 25% against pendings down 10% is the pattern of a market slowly shifting toward buyers, and higher rates in 2027 extend it. That argues against price gains.
But most owners do not have to sell. A large share of Seattle homeowners locked in far lower rates in earlier years, and someone giving up a low rate needs a reason to move. That keeps a lid on how many homes come to market and argues against a sharp drop.
And the market is already pricing in the difference between good and bad listings. In September, 51% of Seattle house sales closed within 15 days at their full original price, while the ones that sat past 91 days closed at 87.9% of it. That twelve-point gap is where 2027's price adjustment is most likely to happen: through individual price cuts on overpriced homes, not through a citywide slide.
Southeast Seattle
Southeast Seattle (Mt. Baker, Columbia City, Beacon Hill, Seward Park, Hillman City and Rainier Beach) has been the tightest of the four areas all year, at 2.5 months of supply in September. My Q3 report found that only August touched the four-month line, and it did not hold. I would expect the area to stay neutral in 2027 rather than tip into a buyer's market, with the usual caution that about 35 to 40 houses close here in a month, so any single month's median will swing.
The Eastside
The Eastside already crossed into buyer's territory at 4.1 months of supply, with nearly half of September's sales requiring a price change first. Higher rates hit hardest where prices are highest, so I would expect the Eastside to remain the area with the most negotiating room in 2027. For one slice of it in detail, see my Rose Hill guide.
Condos
Condos are the softest part of every market. Seattle condos carried 7.3 months of supply in September, well past the four-month line, and 57% of sales changed price or relisted before closing. Higher rates give that no reason to tighten. If you are deciding between formats, my condo, townhouse and house comparison covers what each costs to own.
What Would Change the Picture
Three things would make this forecast wrong, and they are worth watching more closely than any headline prediction.
- 01Rates falling toward the low 6s. This is the Goldman case. If it happens, demand that has been waiting on the sidelines comes back quickly, and the growing inventory of 2026 gets absorbed fast. Spring 2027 would then look more competitive than this article suggests.
- 02Rates rising further. Fannie Mae and the MBA both moved their forecasts up by most of a point in one month. Another move like that would push more of Seattle toward the Eastside's position: more price cuts and longer selling times.
- 03Months of supply crossing four in Seattle. That is the line between neutral and a buyer's market, and the monthly updates will show it the moment it happens. Seattle was at 3.0 in September.
What This Means for You
- 01If you're selling in 2027: expect more competing listings than you would have had in 2025, and price to the comparable sales that actually closed. The fast lane still exists, and it rewards the right number on day one. My guide to what your Seattle home is worth walks through how to set it.
- 02If you're buying in 2027: waiting is likely to buy you more selection, not a lower payment. If the rate forecasts hold, the leverage you gain is in negotiation, terms and inspection, so use it. Run your budget at today's rate and treat a future refinance as a possible bonus, not the plan.
- 03If you're a first-time buyer: payments are the hurdle, so the programs that help with the down payment and the rate matter more than they did a year ago. My first-time buyer guide covers what Washington offers.
- 04If you're moving up: you are likely selling and buying in the same market, so a softer price on your sale is usually offset on your purchase. The rate on the new loan is the part that changes your math, so weigh what you give up on your current mortgage.
- 05If you're condo shopping: Seattle's condo market has the most room to negotiate of anything in this report. Ask for terms as well as price.
The Bottom Line
The 2027 Seattle market is a rate story, not a price story. The central forecasts have the 30-year rate between about 7.1% and 7.5% for the whole year, which points to slow sales, more inventory, and prices that hold roughly flat rather than rise or fall sharply. The biggest risk to that view is the rate forecast itself, which moved almost a point in a single month this fall.
I will revisit this forecast against the actual numbers as the monthly updates come in. Every month's report, along with the quarterly Southeast Seattle report, is in market updates.

Quick answers
- Will Seattle home prices drop in 2027?
- A sharp drop looks unlikely, but neither does a rebound. Seattle ended September 2026 with a median house price of $960,000, down 2% from a year earlier, on 3.0 months of supply, which is a neutral market. With the major forecasters expecting mortgage rates to stay above 7% through 2027, the more likely path is flat to slightly soft prices, more homes to choose from, and longer selling times, rather than a crash.
- What will mortgage rates be in 2027?
- In their October 2026 forecasts, Fannie Mae expects the 30-year fixed rate to average 7.5% in every quarter of 2027, and the Mortgage Bankers Association expects 7.2% for the first three quarters and 7.1% in the fourth. Both revised up sharply from a month earlier, so treat any rate forecast as a range rather than a promise.
- Should I wait until 2027 to buy a house in Seattle?
- Waiting only pays if prices fall faster than rates rise. In September 2026 that stopped happening: the monthly payment on a median Seattle house rose year over year even though the price fell. If the rate forecasts hold, waiting buys more selection, not a cheaper payment. Buy when the house and the payment both work, and treat a future refinance as a possible bonus rather than the plan.
- Is 2027 a good time to sell a house in Seattle?
- It can be, if the price is right from the first day. In September 2026, about half of Seattle house sales closed within 15 days at their full original asking price, while the ones that sat past 91 days closed at 87.9% of it. Expect more competing listings in 2027 and price to the sales that actually closed, not to the 2025 peak.
