Paul Bergeron bought his first floating home in the 1980s for a fraction of what a comparable home costs today. That appreciation trajectory — dramatic over the long run — is often the first thing buyers think about when they consider a floating home as an investment. The question is whether the next 20 or 30 years look as compelling as the last 40, and the honest answer involves understanding both what has driven appreciation and what the risks are going forward.
The Supply Constraint
The single most important factor in Sausalito floating home appreciation is supply. There are only a finite number of permitted floating home slips in Richardson Bay, and that number has not materially increased in decades — and is highly unlikely to increase in the future. The Bay Conservation and Development Commission controls development in the Bay and is not permitting new large-scale floating home communities. Every buyer who wants to live on the water in Sausalito is competing for the same fixed pool of homes.
This supply constraint is structural and durable. Barring a radical shift in BCDC policy or a major natural disaster, the number of floating home slips in Sausalito in 2036 will be approximately the same as the number today. Against that fixed supply, demand continues to be generated by a Bay Area that is consistently among the most economically vibrant regions in the world.
Appreciation History
Floating homes in Sausalito have appreciated substantially over time, though the trajectory has not been linear. The community saw strong appreciation through the 1990s and 2000s, a slowdown during the 2008-2012 downturn (though floating homes held value better than many asset classes in that period), and strong appreciation since 2015 as Bay Area real estate broadly recovered and then accelerated. Homes that sold in the $200,000 range in the 1990s have in many cases reached $800,000 to $1.5 million in subsequent sales.
The appreciation rate reflects both the supply constraint and the increasing quality of the homes themselves. The floating home stock has been substantially improved over the past 30 years — older, more primitive vessels have been renovated or replaced by better-built, more comfortable homes that appeal to a broader buying pool.
Risks to Understand
Floating home investments carry risks that land home investments don't. Financing constraints mean the buyer pool is smaller and slower to move than for conventional real estate, which can extend days-on-market and introduce price volatility in down cycles. Maintenance costs are higher and less predictable — a hull repair event can cost tens of thousands of dollars and is not always foreseeable. The slip lease structure introduces a dependency on an external party (the marina or dock authority) that doesn't exist in fee-simple land ownership.
Climate change and sea level rise are long-term considerations for all Bay-adjacent real estate. Floating homes have an inherent adaptability to gradual water level changes — they rise and fall with the water — that fixed-foundation buildings don't have, but the broader infrastructure of marina access, utilities, and dock walkways is not self-adjusting.
For buyers who buy with a long time horizon and a genuine love of the lifestyle, Sausalito floating homes have been excellent investments. For buyers primarily motivated by short-term return, there are better-liquid real estate options. Paul's advice, based on 40 years of experience: buy what you love to live in, and the investment case takes care of itself.
