When you buy a used houseboat, you're choosing a path that combines adventure with affordability. With 407 used houseboats currently on the market, finding your floating home has never been more accessible.
Quick Answer: Where to Start
The used houseboat market offers everything from cozy 28-foot models to sprawling 128-foot floating palaces. Most average 50 feet and accommodate 10 passengers. Why buy used? A new houseboat depreciates instantly, while a used vessel has already taken that financial hit. You get proven performance, maintenance records, and unique character.
The process is straightforward: search listings, inspect with professional help, arrange financing, and complete the paperwork. The key difference is your property floats. Living on a houseboat averages $955 per month—often less than traditional housing. You'll pay moorage fees instead of property taxes in many states, and utilities are typically lower.

Living on the water is a dream, but new houseboats are expensive. That's why used houseboats are often the smarter choice. When you buy a used houseboat, you're not settling; you're making a savvy investment that gets you on the water faster and with more money to spare.
| Factor | New Houseboat | Used Houseboat |
|---|---|---|
| Purchase Price | Significantly higher | Substantially lower |
| Depreciation | Rapid initial depreciation | Slower, more stable depreciation; initial hit absorbed |
| Customization | Built to your specifications (long wait) | Often comes with upgrades/personal touches from prior owners |
| Known History | None | Maintenance records, survey reports, past usage data |
| Warranty | Manufacturer's warranty (limited duration) | Typically sold "as-is" (unless through a dealer) |
The most obvious perk is saving a fortune. New houseboats can cost millions, but quality used options are often around $50,000. Depreciation is your friend when buying used. The original owner absorbed the initial, rapid loss in value, making your vessel a more stable investment. A lower initial investment means less financial stress and more budget for repairs, upgrades, or simply enjoying your new lifestyle.
Used houseboats often come with upgrades paid for by the previous owner, like modern interiors, new engines, or custom woodwork. Established maintenance records offer transparency, helping you understand the boat's history and budget for future needs.
Of course, used houseboats have challenges. Wear and tear is inevitable. Engines have hours on them, and systems age. You may face repairs sooner than with a new boat. Outdated systems, from electrical to navigation, may need upgrading, which can be costly.
The biggest concern is hidden issues. Most are sold "as-is," so problems found after the sale are yours to fix. This could include hull cracks or engine failure. Financing can also be trickier for older vessels, potentially leading to higher interest rates or larger down payments.
However, these downsides aren't dealbreakers. A thorough marine survey can uncover most problems. With proper planning and professional help, a used houseboat is a smart choice for starting your floating home adventure.
The hunt for your perfect used houseboat is exciting, and knowing where to look is key.
Online marketplaces like Boat Trader, YachtWorld, and BoatCrazy list hundreds of used houseboats, with prices from $6,290 to over $1.4 million. You can filter by location, price, length, and manufacturer. Specialized boat brokers, especially in houseboat-rich areas like Puget Sound, offer personal expertise and insider knowledge. They can guide you through the entire process.
Walk the docks at local marinas. You might find a "For Sale" sign on a hidden gem that isn't listed online. Private seller listings on Craigslist or Facebook Marketplace offer direct access to owners. In the Pacific Northwest, searching seattle boats for sale by owner "houseboat" - craigslist can uncover local treasures.

When you buy a used houseboat, choosing between a private seller and a dealer presents different trade-offs. Private sellers may offer better prices and more negotiation room, but sales are typically "as-is," and you'll handle all the paperwork yourself. Dealers and brokers provide structure and protection. They handle paperwork, ensure the boat is seaworthy, and may offer limited warranties. While you might pay more, the peace of mind is often worth it.
Match the houseboat to your needs by considering these key factors:
A thorough inspection is the most critical step when you buy a used houseboat. Don't treat it as optional; it's your best defense against costly surprises. We strongly recommend hiring a professional marine surveyor. Their expertise and specialized tools can spot problems an untrained eye would miss. They are an unbiased expert with no stake in the sale.
A comprehensive survey covers the hull, engines, generators, electrical and plumbing systems, safety equipment, and overall condition. The final report is your roadmap, detailing the boat's health and any needed repairs. Pro tip: Accompany the surveyor during the inspection. It's a great learning opportunity and allows you to ask questions in real-time.

When you buy a used houseboat, you're buying several interconnected systems. Here are the critical areas that deserve attention:
Knowing common problems helps you spot red flags during viewings:
After finding and inspecting your boat, the next step is navigating the costs and paperwork. The purchase price, ranging from $6,290 to over $1.4 million, is just the start. Understanding the full cost of ownership is key to budgeting realistically when you buy a used houseboat.

Ongoing costs include moorage fees, which vary by marina and location, and marine insurance, which is required by most marinas and lenders. You'll also have annual registration fees. Unlike homes, houseboats often don't incur property taxes, which can be a significant saving. Finally, budget for routine maintenance and repairs.
Most buyers will need financing. Traditional mortgages don't apply, as houseboats are personal property. Instead, you'll seek a loan from a specialized marine lender. Marine loans function like RV financing, and you can often Instantly Pre-Qualify for a boat loan to see your options.
Down payments are typically 10-20%, and loan terms can extend up to 20 years, making monthly payments manageable. Real estate professionals specializing in floating homes, like our team at Special Agents Realty, have relationships with lenders who understand this unique market and can guide you to the right resources.
The legal transfer of ownership involves several key steps:
Once you've closed the deal on your used houseboat, you need to get it to its new slip. How you do this depends on the boat's location and design.
If the new marina is nearby, transporting by water is the simplest option. This can be done under the boat's own power or with a tow. Ensure the boat is seaworthy, with adequate fuel and safety gear. Piloting a large vessel requires experience. If you're not confident, hiring a licensed captain for the delivery is a wise and safe investment.
For long distances or land-locked boats, you'll need a professional boat hauler. They use specialized trucks and trailers and understand how to move oversized vessels safely. Overland transport involves permits and regulations for oversized loads, which vary by state. Professional haulers handle this complex paperwork as part of their service.
You must prepare the boat for transport. This includes securing loose items, draining water tanks, disconnecting batteries, and sometimes removing tall structures like flybridges to meet height clearances. Your hauler will provide a checklist.
Finally, coordinate with your new marina. Inform them of your arrival time so your slip is ready. They can assist with docking or arranging a crane if arriving by truck. This process may seem complex, but with good planning and professional help, your used houseboat will be settled in its new home, ready for the adventure to begin.
Often, yes, but it depends on your location and lifestyle. The average cost to live on a houseboat is around $955 per month, which is often lower than traditional housing, especially in high-cost areas like Seattle. A key difference is paying moorage fees instead of property taxes, which can be a major saving. Utility costs are also typically lower due to the smaller living space. However, you must budget for ongoing maintenance, as marine environments are harsh and specialized repairs can be more frequent than with a land-based home. For many, a used houseboat offers a genuinely affordable lifestyle.
Not a traditional one, but financing is available. Traditional home mortgages don't apply because houseboats are classified as vessels, not real estate. Instead, you'll get a specialized marine loan from a lender who understands the boat market. These loans work like RV financing, with down payments around 10-20% and terms up to 20 years. Interest rates depend on the boat's age, value, and your credit history. Working with a knowledgeable broker who specializes in floating homes, like our team at Special Agents Realty, is invaluable. We have relationships with specialized lenders and can guide you through the process. The provided link to Instantly Pre-Qualify for a boat loan can be a helpful starting point.
Moving your used houseboat depends on its location and destination. Water-based delivery is simplest for short distances, either under its own power or by tow. If you're not an experienced pilot, hiring a professional captain is a smart, safe choice. Overland transport is necessary for long-distance moves and requires a professional boat hauling company. This involves significant costs and logistics, including oversized-load permits, which the hauler typically handles. You'll need to prepare the boat by securing loose items and draining tanks. Finally, coordinate with your new marina to ensure your slip is ready. While it seems complex, proper planning and professional help make the move manageable.
We've covered the journey of buying a used houseboat, from finding and inspecting to financing and paperwork. Now, the real adventure begins. Buying a houseboat is a lifestyle choice. Imagine waking up to water views and the sound of gentle waves instead of traffic. This can be your everyday reality.
A houseboat offers freedom and flexibility, whether for weekend getaways or full-time living. It's a unique lifestyle with a passionate, tight-knit community. Choosing a used vessel makes this dream achievable. The investment is lower, and with average living costs around $955 per month, it's more accessible than many realize.
The process involves work—inspections, paperwork, and maintenance are all part of ownership. But you don't have to steer it alone. In the Pacific Northwest, local experts can make all the difference.
