For those of us seeking the appeal of a minimalist life on the water, the cost to build a houseboat will depend as much on how much elbow grease we’re willing to dedicate to the project as it does on the type of materials we decide to use for the job.

A houseboat is a self-propelled vessel with a cabin. There are many styles, giving people wide discretion on how they choose to build their own houseboat.

Let’s break down factors and average costs associated with building a houseboat.

Average Cost of Building a Houseboat

How much does it cost to build a houseboat? Just like the cost to build a house, it depends on size, materials, whether it’s a total DIY job, and more.

The cost of building a single-story 50-foot houseboat is at least $20,000 and perhaps closer to $50,000, some sources say. To be clear, that low estimate means doing all the work yourself or with the help of friends.

Labor costs for professionals like electricians or plumbers will increase your expenses substantially. So understand that you’ll be trading time and know-how for savings.

There are also houseboat kits and plans for sale. Charmingly, some are advertised as DIY pontoon tiny houses.

By contrast, you can choose to purchase a serviceable preowned houseboat that needs some renovations. Used houseboats can go for anywhere from around $20,000 to way over $1 million (or multi-millions) for luxury craft that border on liveaboard yachts. A houseboat in good condition is generally going to cost you around $60,000 to buy used. Shiver me timbers!

Here’s a rough estimate of the cost of building a houseboat vs. buying a used one.

Regardless of whether you’re planning to handle the build yourself or you intend to refurbish a used houseboat, you may need financing. How to pay for it? Not with a traditional mortgage. Options include a boat loan and a personal loan.

Homeowners with sufficient home equity may be able to launch their houseboat plans with a home equity line of credit (HELOC), home equity loan, or cash-out refinance.

Factors That Affect the Cost of a Houseboat

Houseboat living has caught on with some retirees, who want to downsize home-wise.

It also could be a choice for minimalists and millennial homebuyers who think outside the box.

Not everyone, of course, will want to be a full-time liveaboard. Some water lovers will be OK with a basic houseboat for cruising and recreation, one that is maybe trailerable. Those are factors that will affect the cost of your preferred houseboat.

Here are factors to consider.

Size

The size of your houseboat will have a major impact on the cost of materials you’ll need. Are you planning to build a single-story or double-decker houseboat? Will this be something that would fit on a standard 50-foot pontoon base, or will you need something more robust to keep it afloat?

Consider the cost of $50,000 to build a basic 50-foot houseboat that will probably end up offering 450-500 square feet of space. That comes out to at least $110 per square foot, assuming you don’t hire anyone to help with construction. Your houseboat project could very well end up costing more than $200 per square foot.

Bear in mind that these figures are a very rough estimate that was calculated across a broad average of houseboats.

Design

The design of your houseboat will have a large effect on your options when it comes to layout, maneuverability, and aesthetics.

Before you begin construction, you’ll need to decide on what type of hull best suits your houseboat. Aluminum pontoons are popular.

Catamaran cruisers are maneuverable and may be cheaper to build, but they often compromise on space. These designs are easily outfitted with motors and may be best suited for owners who intend to take them out occasionally.

Those looking for larger accommodations may prefer a type of house called a floating home, which is actually different from a houseboat. It often has a concrete hull and is meant to stay in one place, permanently attached to utilities. The price, though, will usually be much higher than that of a houseboat.

A few sailors may opt to build a yacht, which offers the ideal combination of maneuverability and living space. You’ll have to have a hefty check at the ready or prepare to borrow a boatload if you’re considering this option.

Materials

The most common materials used to build boats intended for habitation are aluminum and fiberglass, but in some cases steel and wood can be construction materials of choice.

A standard pontoon base can cost between $3,000 and $10,000.

The cost of interior finishes largely depends on your personal tastes. They can be affordable if you’re fine with a no-frills setup but can tack skyward for more luxurious tastes and larger vessels. Stainless steel appliances and granite countertops cost money, regardless of whether they go in a house or a houseboat.

Will you want a staircase and flybridge? Budget accordingly.

Location and Water Depth

The environment you intend to keep your houseboat in will affect how much you’ll have to pay to make it seaworthy.

The price of an inboard motor may start around $8,000 and go up to $25,000. An outboard could start at $1,000 and go up to around $15,000. Depending on how large your vessel is, you may need to pay for a larger motor with more horsepower.

Federal regulations governing recreational craft prohibit the majority of houseboats from sailing in deep ocean waters. However, cruises along the shoreline, or in a lake or river, are acceptable options for capable houseboats.

Weather

Whether you decide to launch or keep your houseboat in freshwater or saltwater and local weather patterns will affect houseboat maintenance.

Saltwater is a tougher environment but has a lower freezing temperature than freshwater, which means that you likely won’t have to worry about ice forming in the water.

By contrast, if your houseboat will primarily be in freshwater, you may have to deal with ice. As water freezes into ice, it expands, which can damage your hull or rudder.

Permits and Regulations

Any recreational vessel must meet federal safety requirements and possibly abide by state regulations.

Average Cost of Living on a Houseboat Year-Round

The average cost of living on a houseboat is $30,000 per year, including a boat or personal loan payment, some sources say. This breaks down to around $2,500 per month. Some frugal houseboat enthusiasts report living on as little as $6,000 per year.

Most of these costs encompass mooring fees, utilities, and insurance, but you’ll also need to budget for repairs and applicable local fees. Some houseboat communities have a homeowners association that allows all residents to distribute community expenses like maintenance of the docks.

Does a houseboat cost less than a home sitting on terra firma? Generally, yes. You can build a houseboat for far less than a comparably sized single-family home. As a future liveaboard, though, you might want to compare moorage and other fees to the costs of maintaining a traditional home.

The IRS says a boat with cooking, sleeping, and toilet facilities can be a main or second home, so interest paid on a loan for your houseboat could be included in the mortgage interest deduction if you itemize.

The Takeaway

How much does it cost to build a houseboat? The cost could start at $20,000 for a DIY build and depends largely on size and materials. Hiring skilled labor will add to that substantially. An alternative to building a houseboat is buying a used one and making it your own. How to pay for these nautical visions? One way, for qualified homeowners, is a HELOC brokered by SoFi.

SoFi now partners with Spring EQ to offer flexible HELOCs. Our HELOC options allow you to access up to 90% of your home’s value, or $500,000, at competitively lower rates. And the application process is quick and convenient.

FAQ

How large can a houseboat be?

In most cases, 40 to 50 feet is the average length and 8 to 20 feet the range of width for a houseboat that will be comfortable as a long-term dwelling.

How long does it take to build a houseboat?

A DIY houseboat project could easily take 18 months to complete, but the time frame will depend on whether you’re able to work on the houseboat project full time and whether you enlist any help. Remember to factor in time to obtain necessary permits or inspections for your area.

Where can I get financing to build a houseboat?

You may be able to finance your houseboat build through lenders that focus on marine and RV lending. Other options are a personal loan, a HELOC, a home equity loan, and a cash-out refinance.

With the rise of environmental and climate-related concerns, more people are becoming familiar with the term greenwashing — which is when a company markets itself as more sustainable or environmentally friendly than it actually is.

Greenwashing impacts investors and consumers alike because it’s designed to mislead people through a variety of means, including: the use of vague terminology or false labels; making claims about green actions or outcomes that can’t be verified (or are found to be deceptive); using false or misleading research and data.

The term greenwashing is derived from the notion of whitewashing, which is when a company or individual conceals wrongdoings by presenting a cleaned-up, but deceptive version of their actions.

Types of Greenwashing

For some companies, greenwashing is a means to attract consumer and investor dollars. According to the 2023 Business of Sustainability Index, 68% of consumers said they’re willing to spend more money for environmentally friendly products.

But some companies engage in greenwashing to appear compliant with environmental regulations, which can be stringent and come with hefty penalties — especially now that some countries, like the EU. and U.K., are adopting anti-greenwashing laws.

Before you buy products marketed as sustainable or eco-friendly, or invest in a green company that makes similar claims, it may help to know the different types of greenwashing.

•   Greenwashing a polluting product: Companies may attempt to improve the branding of a product by making it seem more environmentally friendly without actually changing much or anything about it.

•   False associations: Brands can make it seem like they are endorsed by a third party when they really aren’t, or the third party is simply their own subsidiary.

•   Green products from a polluting company: A company might make a product that has a lower environmental impact, such as an electric vehicle, but manufacture it in a way that creates significant waste and greenhouse gas emissions nonetheless.

Again, because socially responsible investing has grown so rapidly, and many companies want to attract the attention of investors and consumers with a green sensibility, there is commensurate growth on the greenwashing side, so it pays to be cautious when making choices.

💡 Quick Tip: How do you decide if a certain online trading platform or app is right for you? Ideally, the online investment platform you choose offers the features that you need for your investment goals or strategy, e.g., an easy-to-use interface, data analysis, educational tools.

Example of Greenwashing

Greenwashing is increasingly on the radar of regulatory bodies that protect consumers and investors. But some watchdog organizations lack the resources to hold companies to account. A few examples of what would be considered greenwashing are described on the U.S. Federal Trade Commission (FTC) website:

•   A company labels a trash bag they are selling as “recyclable.” Although this may be true, it’s unlikely that a bag full of trash will be emptied and then recycled on its own. This label makes the product appear to have an environmental benefit, but in reality it doesn’t.

•   In another example, a company labels a product as having 50% more recycled content than a previous product did. This makes it sound like a significant amount, but in fact the company may have increased the recycled content from 2% to only 3%, so in reality there has been hardly any change.

•   A company labels a product as “recyclable” but they don’t say specifically whether all parts of it are recyclable, just some parts, or just the packaging.

Other real-world examples include: An oil company that’s known for environmental negligence releases advertisements that state their dedication to a carbon-free future — or companies promising to do environmental cleanups, but failing to actually follow through on those promises.

The Negative Impacts of Greenwashing

Although in the short term greenwashing might benefit a company if it leads to more people buying their products, the risk is that a revelation of greenwashing practices could quickly and negatively outweigh those gains.

The Impact on Consumers

If consumers catch on that a company is engaging in greenwashing, rather than adhering to ESG standards, there could be a public relations backlash. Consumers may feel duped, and may express their discovery of a company’s contrary claims in various ways: with other consumers, on social media, writing to elected officials, contacting the Better Business Bureau.

Depending on the scale, and the level of consumer awareness, this has the potential to damage a company’s reputation and trustworthiness, and cause consumers to turn to other brands.

In addition, companies that get caught greenwashing can also face legal ramifications for their misleading claims. And investors interested in true impact investing may take their business elsewhere.

The Impact on the Environment

In the long term, the biggest negative consequence is the actual environmental impact of manufacturing and other business practices that are not, in fact, green or sustainable. By using green claims to bolster their business goals, yet not living up to actual sustainability standards, companies not only add to environmental damage, they hinder efforts to create sustainable products and reach other socially responsible goals.

Companies rely on clean water and air, quality soil, viable supply chains, and a stable climate to operate. A thriving economy requires a healthy planet, and greenwashing ultimately doesn’t support either.

The Impact on Investors

Just as many consumers are seeking a clearer understanding of the environmental claims of various products and consumer goods, investors are looking for ways to vet the claims of financial companies that offer ESG-focused securities, like exchange-traded funds (ETFs) and mutual funds.

This has led some organizations to develop ESG frameworks, in order to provide investors with a way to assess companies’ ESG progress, and use accepted standards and metrics to compare one company to another. Companies that make ESG claims for their investment products can come under regulatory scrutiny, and may face substantial fines.

How to Spot Greenwashing

Many greenwashing tactics can be convincing. Here’s what to look out for when purchasing a product, or investing in a company that claims to embrace sustainability or ESG investing strategies (i.e., environmental, social, and governance practices):

•   Vague language: Labels such as “eco-conscious,” “clean,” or “100% sustainable” don’t actually mean anything in terms of a company’s manufacturing processes or adherence to environmental criteria. Be sure to research ESG standards that reflect actual environmental practices.

•   Natural imagery: If a polluting company uses marketing images of flowers, trees, beaches, and so forth, they may be trying to appear more environmentally friendly than they really are. Be sure to check whether the company or product lives up to the advertising.

•   Fabricated data: Companies might fund research that will provide “results” that make them look better, or make data up completely. In some cases, it’s easy to vet company research or data via the company website or by doing an internet search.

•   Grand claims: Some companies may pledge to reduce carbon emissions or announce a net-zero policy (or another ambitious goal), with little to back up the claim.

How to Avoid Greenwashing

Whether purchasing products or investing in companies, if you are looking for the most sustainable options, there are a few ways to avoid greenwashing.

1. Look for Clear and Transparent Language

If a brand makes sustainability claims, look for specifics such as certifications, verifiable third-party endorsements, industry credentials, and details about exactly what the brand is doing.

2. Evaluate the Data

If a brand uses statistics and numbers to back up its sustainability claims, make sure the numbers are backed up with credible data.

3. Compare Similar Products

A company may make sustainability claims when in fact their product has basically the same environmental impact as a competitor’s. Compare ingredients, packaging, and manufacturing information to see whether one product is really better than another.

4. Look Beyond the Final Product

Even if a company is improving the impact of its products, it may not be addressing the waste and emissions associated with its operations or supply chain. If this is the case, they may be just making changes for marketing purposes. Check out a company’s website and/or follow watchdog groups to learn how much effort is going into sustainability at the corporate level.

5. Look for Goals and Timelines

If a company is truly implementing a comprehensive sustainability plan, it would include measurable goals and timelines. Ideally those would be available to investors and consumers on a public forum such as the company website, in the interest of transparency.

6. Verify Ingredients and Materials

Some terminology and product labels can be misleading. For instance, a company might say that their product is made from organic cotton or recycled plastic, when in fact only a small percentage of the cotton or plastic is organic or recycled and the rest is not.

The FDA has no guidelines for what the term “natural” means, and according to the USDA the term simply means that a product is “minimally processed” with “no artificial ingredients.”

Greenwashing vs. Green Marketing

Although greenwashing is when a company attempts to cover up their bad practices, there is nothing wrong with a company telling the story of its environmental initiatives, and the steps it’s taking to produce products more sustainably.
That’s green marketing at its best and most transparent.

How to Recognize Green Marketing

Actual green marketing may include:

•   Certifications and endorsements from established regulatory organizations

•   Clearly labeled manufacturing processes

•   Recyclable, compostable, or biodegradable materials (but watch out for these labels, sometimes a product can actually only be composted or biodegrade in very specific conditions that aren’t realistic).

•   Products free from toxic chemicals

•   Use of renewable energy

•   The use of transportation measures such as EVs

•   Purchase of carbon offsets for any unavoidable emissions

•   In-office programs and measures such as renewable energy, LEED certified buildings, on-site composting, or elimination of single use plastic

•   Doesn’t use too much packaging, and ideally avoids plastic packaging

•   Circularity programs that allow consumers to send back the product for repair or reuse

•   High-quality manufacturing made to last rather than one-time or short-term use

•   Fair trade and ethical labor practices

•   Environmental programs outside the company, such as donations or volunteer efforts

Greenwashing Regulations

There are currently no laws in place to prevent greenwashing practices in the U.S. The FTC does have a set of Green Guides, which are not mandatory, but can help companies avoid falling into greenwashing territory.

Globally, the outlook for anti-greenwashing measures is somewhat more robust. The last couple of years have seen a rise in anti-greenwashing policies or preliminary taskforces in various countries around the world.

•   The EU Green Claims Directive is a new law that was approved by the European Parliament in 2024, and is now being enacted by member states, with a September 2026 target date for implementation.

•   In the U.K., the Green Claims Code is a set of principles that businesses must adhere to, or face regulatory consequences.

The Takeaway

Greenwashing is a marketing tactic some companies use to align themselves with the growing consumer and investor desire for sustainable products and investments. It’s related to the concept of “whitewashing,” which means covering up the truth with a positive-sounding story.

Investors committed to sustainability can look for red flags of greenwashing before deciding whether to invest.
