The North Bay real estate market stands apart from national trends, according to Steven Cozza, team leader at Compass in Petaluma, California. While many regions across the U.S. have seen inventory rebound or even surge, Sonoma and Marin counties remain defined by a severe shortage of available homes. This persistent scarcity is forcing buyers and sellers to adopt new strategies and is changing how deals get done in one of the Bay Area’s most sought-after regions.

Inventory Constraints

The supply crunch in Sonoma and Marin counties is now the defining feature of the local market. While cities like Austin are grappling with excess inventory and sluggish sales, North Bay agents face the opposite challenge: too few homes to meet steady demand.

“One of the problems here in Sonoma County, Marin County, is the lack of inventory,” Cozza says. “Different parts of the US have over-inventory, like Austin has too much inventory, and they’re flooded with way too many properties. But then you have where we are, and it’s this crazy restriction of inventory.”

This imbalance has wide-ranging effects. Buyers face limited choices and intense competition for desirable properties, while sellers with realistic expectations can still command strong prices. For agents, the shortage means the traditional model of waiting for listings to appear on the MLS is less effective. Instead, proactive outreach, networking, and alternative deal structures have become essential.

Off-Market Transactions

As inventory has tightened, off-market sales have become a major avenue for both buyers and sellers. These transactions occur outside the public listing system, often through private networks or direct negotiation. Cozza’s team, which splits its business equally between buyers and sellers across all price ranges, has found off-market deals to be a reliable way to secure homes in an environment where new listings are scarce.

A recent example involved a home that had been withdrawn from the market during the holidays. Cozza reached out directly to the owners on behalf of a client, negotiated a $100,000 reduction from the previous asking price, and closed the deal without the property ever returning to the public market. For sellers, the certainty of a private deal often outweighs the potential for higher offers through a public listing, especially when it means avoiding further price cuts and the hassle of preparing a home for showings.

Off-market deals also appeal to owners who are not actively looking to sell but are open to the right price. Many have what Cozza describes as a “make me sell” number – a figure at which they would consider a sale if approached privately, without the need for staging or public marketing. “I have a make me sell price for my home,” Cozza says. “There’s a number that I would sell it at if someone approached me, but I don’t want to take the time to get it all staged and go through all that.”

Technology Expands Access

Recent advances in real estate technology are accelerating the off-market trend. Compass’s private exclusive program, which started as a way to give sellers limited exposure before a full public launch, has grown into a robust platform for private transactions. The recent partnership between Compass and Redfin is poised to further expand access to these listings.

“If 20% of the inventory is a private exclusive, and now it’s going to be on Redfin but not Zillow, you’re going to drop Zillow so fast,” Cozza predicts. With more off-market properties available on select platforms, buyers will increasingly need to use multiple sources to see the full range of options. This development could reshape which websites and apps buyers rely on, making access to private networks and proprietary listing pools more important than ever.

A Market And Broader Trends

National headlines often cite rising inventory and slowing sales, but the North Bay remains a seller’s market – though with important caveats. “We’re still in a pretty good seller’s market, with some pockets where homes are sitting,” Cozza says. The homes that linger on the market are typically those purchased during the peak years of 2021 to 2024, when bidding wars and rapid price escalation led some buyers to overpay. Owners of these properties often hope to recoup their investment, plus commissions and fees, but the market no longer supports those inflated values.

“Those sellers think they can get the same price or even higher because they need to cover commission and fees, but they’re realizing they overpaid in those hot markets when there were seven or eight offers,” Cozza explains. “Now you’re seeing one or two offers, and those overpriced homes are sitting.”

By contrast, other parts of the Bay Area, such as Silicon Valley, continue to see intense bidding. In February, 40 homes there sold for $200,000 or more over list price, with 17 exceeding the list by at least $400,000. “We’re not seeing that in Sonoma Marin County,” Cozza notes. “We’re seeing more of a normalized market – not seeing crazy increases, but not seeing declines either. Just a more steady market.”

Insurance Costs

Another unique challenge facing the North Bay is the rising cost and limited availability of fire insurance, particularly in rural and forested areas. Cozza points to a Guerneville triplex priced at $750,000 that would normally attract investor interest. Instead, monthly insurance premiums of $1,300 have made the property financially unviable for investors.

“It would sell in a heartbeat if insurance were normal on the property,” Cozza explains. “With insurance the way it is, no investor would ever buy that property. It’s no longer an investment property.” In these cases, sellers are forced to market to owner-occupants who might use rental income to offset costs, rather than to pure investors.

Economic Uncertainty

Wider economic concerns also play a significant role in buyer and seller behavior. Cozza points out that fear of layoffs and market downturns is causing hesitation among buyers, especially those whose down payments are tied up in investment accounts or cryptocurrencies rather than traditional bank savings. This reliance on volatile financial markets means buyers are more sensitive to fluctuations and may delay purchases if their portfolios take a hit.

“Fear is a big factor in buyers’ motivation,” Cozza observes. “They’re worried about getting laid off, worried about financial markets crashing. That’s where they get their money – they’re not keeping it in banks, they’re keeping it in financial markets or Bitcoin.”

Looking Ahead

The outlook for the North Bay market will depend heavily on interest rate movements and overall economic stability, but the underlying inventory shortage is expected to persist. As a result, off-market opportunities will remain a critical tool for both buyers and sellers.

For agents, success in this environment requires a more proactive and creative approach. Relying solely on public listings is no longer sufficient. Instead, effective agents are combining traditional relationship-building with new technology platforms to identify potential sellers and structure deals before properties ever hit the MLS.

Cozza’s experience underscores the importance of adaptability. In an era of limited inventory and heightened buyer caution, agents who can source hidden opportunities, navigate complex insurance landscapes, and guide clients through off-market transactions will be best positioned to succeed.

Ultimately, the North Bay’s real estate market is rewarding those who act early, think creatively, and leverage both personal networks and emerging technologies. As the market continues to diverge from national patterns, buyers and sellers who understand the local dynamics – and work with professionals who can access the full spectrum of available properties – will have the greatest advantage.
