Sonoma County HousingMarket Update — March 2026
Iran, Interest Rates, and What Buyers & Sellers Need to Know This Spring
If that headline caught your eye, good — it should. Mortgage rates dropped to 5.98% just a few weeks ago, the lowest we had seen since 2022. Then U.S. and Israeli strikes on Iran sent them back above 6.1% almost overnight. Meanwhile, here in Sonoma County, the spring market is beginning to stir — inventory is climbing, pending sales are up nearly 50% from January to February, and the data is telling a very specific story about what is working and what isn’t for buyers and sellers right now.
This post breaks all of it down: the Iran rate story, what our local MLS data actually shows, and exactly what you should do if you’re thinking about buying, selling, or just keeping tabs on your home’s value heading into spring.

1. Why the Iran Conflict Is Affecting Your Mortgage Rate
Here’s something most news coverage doesn’t explain clearly: a military conflict thousands of miles away can directly change what you pay each month on a home in Petaluma or Santa Rosa. Here’s why.
Iran sits at the edge of the Strait of Hormuz the narrow waterway that roughly 20% of the world’s oil supply passes through every day. When conflict threatens that region, oil prices spike. Higher oil prices mean higher inflation fears. And when bond investors get nervous about inflation, they demand higher returns on U.S. Treasury bonds. Mortgage rates follow those Treasury yields almost in lockstep. It’s a direct chain reaction.
| Before the strikes 5.98% 30-yr fixed rate Lowest since 2022 |
| After the strikes 6.1%+ 30-yr fixed rate Rose within days |
To put that in real numbers: on an $800,000 purchase with 20% down, the difference between a 5.98% and a 6.1% rate is roughly $75 per month. Compared to last year’s average rate of 6.63%, today’s buyers are saving closer to $350 per month. That’s real money and it’s why this rate environment, even at 6.1%, is meaningfully better than where we were just twelve months ago.
Where do rates go from here? Experts are genuinely split. If the Iran conflict stays contained and short, rates could drift back down toward that 5.98% level. If oil prices keep climbing and inflation fears persist, rates could push toward 6.5% or higher. The honest answer is that nobody knows and that uncertainty is exactly why waiting for a “perfect” rate has historically cost buyers more than moving forward with a solid plan at a good rate.
The bottom line on rates: 6.1% is not an emergency. It is not 7.5% — the level that froze buyers out of the market in 2023. It is a good rate by recent historical standards, and buyers who understand that are the ones making moves while others wait.
2. Sonoma County Market Snapshot — February 2026
Let’s look at what the local data is actually telling us. One note before we dive in: all price figures below use the median, not the average. This is intentional. A small number of multi-million dollar luxury listings can skew the average dramatically and make the market look very different from what most buyers and sellers are actually experiencing. The median gives you the honest picture of where the typical Sonoma County transaction is happening.
$765K Median Sold Price | 78 days Avg. Days on Market | |
95% Sale-to-List Ratio | 3.1 mo. Months of Supply | ~700 Active Listings |
A few things stand out from these numbers. First, pending sales the leading indicator of buyer demand — jumped nearly 50% from January to February. That’s the spring market waking up. Buyers are writing offers. The pipeline is building. Second, inventory is growing but still lean at 3.1 months of supply. A balanced market is 4 to 6 months we’re still below that, which means the market still leans toward sellers in terms of overall conditions. But individual buyers have more breathing room than they’ve had in years, and that brings us to the most important number on the board.
The sale-to-list ratio of 95% means sellers are accepting, on average, 5% below their original asking price. On a $900,000 listing, that’s a $45,000 negotiation happening at the closing table.
The homes that are transacting the ones closing in days rather than months — share one characteristic: They’re not testing the market. They’re priced to sell.
| For buyers, the gap is negotiating leverage. For sellers, it is a pricing strategy warning. Every day a home sits on the market above the median costs money — in carrying costs, in price reductions, and ultimately in a lower final sale price than a realistic list price from day one would have produced. |
3. What Buyers Should Do Right Now
If you’re thinking about buying in Sonoma County this spring, here is the honest picture: you have more leverage than buyers have had in several years, and you have a window right now that won’t stay open long.
Get pre-approved immediately — not next week
Pending sales are already climbing. The buyers who win when the right home hits the market are the ones who are already pre-approved and ready to move within 24 to 48 hours. The buyers who scramble to get their paperwork together after falling in love with a house lose it. Get your pre-approval done now, before you’re competing with a full spring market.
Use your leverage — but use it wisely
With 78 days on market as the average and sellers accepting 5% below ask, you have real negotiating room. Ask for inspections. Request repairs or credits where warranted. Take time to do proper due diligence. This is a meaningful shift from 2022 and 2023 when buyers were waiving everything just to compete. That said, don’t lowball a well-priced home — correctly priced listings still move quickly and attract multiple offers.
Don’t wait for rates to drop further
The Iran situation is a perfect example of why timing the market on rates is nearly impossible. Rates can move 10 to 15 basis points in a matter of days based on geopolitical events you cannot predict. At 6.1%, you are in a meaningfully better position than buyers who paid 7.5% in 2023. The opportunity is now — and if rates do improve, you can always refinance.
The window is narrowing
Right now there are approximately 700 homes actively listed in Sonoma County. By May or June, based on last year’s seasonal pattern, that number will likely approach 1,400. More inventory means more competition from other buyers. The buyers who move in the next 60 days are the ones with the most selection and the least competition. That window closes fast
5. What Sellers Should Do Right Now
If you’re thinking about selling this spring, the market conditions are working in your favor but only if you approach this with clear eyes on pricing and timing.
List before the competition arrives
This is the most important tactical decision you can make. Right now there are roughly 700 homes on the market. In 8 to 10 weeks, that number will likely double. Every seller who lists before the spring flood has fewer homes to compete against and more buyer attention. The homes that generate the strongest offers and the shortest marketing times are the ones that hit the market in March and early April not May when every other seller has the same idea.
Price it right from day one
Homes sitting at 78 days on market are accumulating those days because they were overpriced at launch. Every day on market signals to buyers that something is wrong, and price reductions rarely recover the full value of that lost momentum. The sellers closing quickly and close to ask are the ones who priced accurately at the start.
Presentation matters more when buyers have options
With 700 active listings and growing, buyers have choices they didn’t have two years ago. The homes winning this market are clean, well-staged, professionally photographed, and priced right. The homes sitting are the ones that cut corners on presentation and priced optimistically. In this environment, those shortcuts cost you.
The spring window is real — and it closes
Historically, April and May produce the lowest days on market and the highest sale-to-list ratios of the entire year. That seasonal pattern holds even in slower markets. If you want to maximize your outcome, those are the months you want to be closing which means listing in March and early April. Every week you wait narrows that window.
6. The Bottom Line
The Sonoma County real estate market in March 2026 is nuanced. It is not the feeding frenzy of 2021. It is not the frozen market of late 2023. It is a functioning market with real opportunities on both sides of the transaction but those opportunities require the right information and the right timing to capture.
Rates at 6.1% are good by recent historical standards. Inventory is lean but growing. Buyer demand is building. And the next 60 days represent a genuine window for buyers to get in before competition builds, and for sellers to list before the market gets crowded.
The Iran conflict adds a layer of uncertainty to the rate picture that nobody can fully predict. What you can control is your preparation, your strategy, and your timing. That’s where I come in.
