38.8% of homes that closed in Sonoma County last month attracted more than one offer. That's nearly 4 in 10 — but the competition isn't spread evenly. Depending on which city and price band you're shopping in, you could be in a bidding war or negotiating below asking.
Where the bidding wars are
263 homes closed across the county in March. The most competitive markets were Cloverdale (57.1% multiple offers), Windsor (53.8%), Petaluma (48.3%), and Rohnert Park (48.0%). All four are primary-residence, mid-price markets where inventory stays tight and buyers outnumber available homes.
The pattern makes sense. These are the cities where families and first-time buyers are most active, and where new listings get absorbed quickly. If you're buying in any of these markets, expect competition — especially on well-priced, move-in-ready homes.
On the other side of the ledger: Bodega Bay, Guerneville, and The Sea Ranch saw zero multiple-offer situations in March. Second-home and lifestyle markets move at a different rhythm, and buyers there tend to have more negotiating room.
The price band that matters most
The $900K to $1.1M range is where competition is fiercest. 58.1% of homes in that band sold over asking, and the average sale price hit 100.2% of list. The $500K to $700K range is also active, with 40.4% selling over asking and 42.3% drawing multiple offers.
Above $1.5M, the picture flips. Only 8.9% of luxury listings sold over asking, and average sale-price-to-list-price dropped to 93.2%. For buyers in the upper tier, there's still room to negotiate — particularly in resort and rural markets.
What Multiple Offers Actually do to Price
Homes that drew multiple offers averaged 101.2% of list price. Single-offer homes averaged 95.6%. That 5.7 percentage point gap is real money — on a $1M home, it's the difference between paying $1,012,000 and $956,000.
But competition alone doesn't explain everything. Pricing strategy, property condition, and location all play major roles. One listing — 4142 Burnside Road in Sebastopol, a mid-century modern — drew over 10 offers. Prized properties in the right location and price range still trigger aggressive bidding.
Cash vs. Loan: The Split
73.8% of March buyers financed with a loan. 26.2% paid cash. The highest cash-buyer concentrations were in lifestyle markets: Glen Ellen (75%), Bodega Bay (66.7%), and The Sea Ranch (62.5%). Santa Rosa, the county's highest-volume market with 96 closings, was the most loan-dependent at just 16.7% cash.
If you're a financed buyer competing against cash in those resort markets, a strong pre-approval and clean offer terms become even more important.
What this means for Sellers
If you're listing in Windsor, Petaluma, Cloverdale, or Rohnert Park — and your home is in the $500K to $1.1M range — conditions favour you. Price it right and present it well, and the market will likely deliver multiple offers.
If you're selling above $1.5M or in a second-home market, the data says expect longer days on market and more negotiation. Realistic pricing from day one matters more than ever in that tier.
