The one-sentence answer
A home equity loan against a houseboat is almost never available, and a floating home can sometimes support one through a short list of portfolio lenders in Washington, Oregon and California. The reason? Legal classification of the collateral. A houseboat is a vessel. A floating home is sometimes real estate.
And Fannie Mae, Freddie Mac, FHA and VA won’t touch either.
Houseboat vs floating home: the test that decides everything
A houseboat has an engine or outboard (or the capacity for one), and it’s designed to move. Its title lives with the state marine authority or the U.S. Coast Guard. The loan against it is a marine loan with 10 to 20 year terms, hull-value capped by vessel age, and rates that run anecdotally from 8% to 15%.
A floating home has no propulsion. It sits on a concrete, wood or steel float, with city water, sewer and electricity hard-connected to the dock. It’s a dwelling first and a structure on water second. Bank of Marin, which lends in Sausalito, requires a concrete hull. Wood-float systems get discounted LTV or declined outright.
Lenders apply a three-part test: capacity to move, permanence of moorage and utility connection, and how the state titles the collateral. Fail any one of these and the file routes to a marine lender rather than a mortgage department.
Why Fannie Mae, Freddie Mac, FHA and VA all say no
Neither Fannie nor Freddie will purchase a loan on a floating home. The agencies require real property with permanent land ownership or a qualifying leasehold, a standardized appraisal, and a clean lien attachment. Floating-home collateral breaks at least two of those every time. FHA doesn’t insure them. VA doesn’t guarantee them.
Because secondary-market exit doesn’t exist, every floating-home loan sits on the originating lender’s balance sheet. That’s why the universe is small, regional and portfolio-only.
State classification: where a true home equity loan is even possible
Washington treats used floating homes as real estate for the real estate excise tax under statute dating to 1984 c.192. Seattle lenders including Banner Bank and Sound Community Bank use deed-of-trust paperwork adapted to the hybrid regime. King County assessors handle valuation on a parcel-equivalent basis for most Lake Union and Portage Bay moorages.
Oregon runs the title through the Oregon State Marine Board rather than the county recorder. Multnomah County assesses the floating home as personal property, taxed each January 1 on real market value. Oregon SB 1559, passed in 2022, removed the annual personal-property return requirement unless the owner adds improvements. There’s no recordable deed in the land records, so a Portland lender’s lien attaches via a UCC-style filing against the marine title. Retain a maritime or real estate attorney to review the lien paperwork before closing.
California treats floating homes as real property for sale and transfer under the Floating Home Residency Law, Health and Safety Code §18075.55 and related revenue sections. Sausalito and Richardson Bay transactions close with title insurance. Bank of Marin lends up to $1,000,000 on eligible one-unit homes with concrete hulls. Enforcement actions against anchor-outs in Richardson Bay have narrowed the pool of lender-approved moorages – something a Sausalito originator will mention before you’ve finished explaining what you want.
Other states run thin. Tennessee’s Kentucky Lake, Lake Cumberland in Kentucky, and the Florida Keys have active houseboat markets, but nearly all collateral there is vessel-titled and routes through marine lenders. True home equity loans are rare to nonexistent.
| Classification | Collateral type | Lender universe |
|---|---|---|
| Houseboat (vessel) | Personal property, marine title | Marine lenders only |
| Floating home, real-property state (WA, CA) | Real estate or hybrid | Regional portfolio banks |
| Floating home, personal-property state (OR) | Personal property, marine title | Narrow portfolio with UCC lien |
The 2026 portfolio lender shortlist
Banner Bank originates floating-home loans in Portland and Seattle. Bank of Marin funds Sausalito and the Richardson Bay market, with a ceiling of $1,000,000 on eligible one-unit homes with concrete hulls. Sound Community Bank runs a Seattle-area floating-home portfolio. FloatingHomeLoans.com operates as a specialty broker and reports equity access through cash-out refi or private bridge rather than a true HELOC. Occasional programs appear and disappear at credit unions including Washington State Employees Credit Union, OnPoint and Patelco.
Portfolio programs change quarterly. Several lenders paused floating-home lending during the 2023 to 2024 rate cycle and reopened in 2025. So confirm program availability directly with the lender within 30 days of any application – the shortlist a broker gave you in April may be shorter by July.
Indicative 2026 terms
Floating-home portfolio loans are quoted at roughly 7% to 8.5% for well-qualified borrowers with 25% or more equity, approximately 1 to 2 points above conforming mortgage rates. LTV and CLTV ceilings sit at 70% to 80% where the collateral has real-property treatment, and they tighten to 65% to 75% where the state treats it as personal property. Term structures are typically 15 to 30 year amortizations with 5/5 or 7-year ARM options. Credit score floors are usually 680 to 720 in lender marketing, though portfolio floating-home programs tend to pull 700 or above in practice.
Marine loans against vessel-titled houseboats run higher, anecdotally 8% to 15%, over 10 to 20 year terms. These are indicative 2026 ranges. Confirm with the lender at application.
Moorage, title and insurance traps that kill most applications
Moorage lease remaining term is the single most common disqualifier. Lenders won’t finance a floating home sitting on a slip with under about 20 years of remaining lease. Fee-simple slips, moorage co-ops and long land-lease moorages are preferred. The economics track the same logic as a short ground lease on a leasehold condominium: a lease shorter than the loan term leaves the collateral valueless at amortization end.
Hull age and construction come second. Concrete hulls are preferred. Wood-float systems get discounted LTV or declined. A marine survey replaces the traditional appraisal at most portfolio lenders, which is why AVM-based home equity products don’t work here.
And then there’s insurance. Flood insurance and hull insurance are mandatory, often with named-perils and sinking coverage, with the lender named as loss-payee. HOA or moorage association litigation and financial distress will stop a file. So will any non-permitted or disputed moorage (a recurring issue in Richardson Bay).
The eight most common decline reasons
The failure modes stack up fairly predictably. Collateral turns out to be a vessel rather than real estate (the houseboat case). The moorage lease has fewer than 20 years remaining. The state treats the floating home as personal property and the lender can’t cleanly perfect its lien. The hull is wood, or has been inspected as deteriorated. Title insurance isn’t available for the moorage interest, or flood insurance isn’t available or isn’t adequate. The HOA or moorage association is in litigation or financial distress. Or the property sits in a non-permitted or disputed moorage, which is its own particular nightmare.
Workarounds when a direct home equity loan isn’t available
So what happens when the floating-home lenders won’t play? The practical answer for many borrowers runs through different collateral. A HELOC on a separate land-based primary residence will fund renovations, debt consolidation or a down payment on a floating-home purchase at conforming rates, roughly 1 to 2 points below floating-home portfolio pricing. Equity has to be sourced from somewhere. It doesn’t have to be sourced from the water.
A cash-out refinance on the floating home itself remains possible with the same three or four portfolio lenders listed above, subject to the same CLTV, moorage, hull and insurance thresholds. A marine refinance on a vessel-titled houseboat is a separate product class – written as a secured personal-property loan, with higher rates and shorter terms. Private and bridge financing is available for distressed timelines, usually at 10% or above, with origination fees of 2 to 4 points.
But home equity investment products from Point, Unlock and Unison are unlikely to fund against floating-home collateral. Point has published a houseboat-financing explainer but hasn’t confirmed program eligibility for either collateral class.
Tax treatment under IRS Publication 936
Publication 936 defines a qualified home to include a boat or vessel that has sleeping, cooking and toilet facilities. A floating home meets the test. A liveaboard houseboat with those facilities meets it as well. The debt has to be secured by the qualified home, which on a houseboat means the vessel loan with the boat as collateral, and on a floating home means a lien attached to the hull or marine title (or to the recorded deed where real-property treatment applies).
Under post-TCJA rules extended by the 2025 One Big Beautiful Bill Act, home equity debt interest is deductible only when the proceeds are used to buy, build or substantially improve the qualified home securing the debt. A taxpayer may deduct interest on debt secured by a primary residence plus one second home. But confirm the current year’s rules in Publication 936 and with a tax professional before relying on the deduction.
What to bring to a portfolio lender
You’ll need a marine survey or hull/float inspection dated within the past 12 months, a moorage lease showing remaining term, assignability and current monthly rate, the current title certificate (state marine board or USCG) or recorded deed where applicable, hull insurance declarations with the lender named as loss-payee, flood insurance adequate for the Special Flood Hazard Area zone, HOA or moorage association financial statements and litigation disclosure, the last two years of personal tax returns, pay stubs or 1099s, and reserves showing 6 to 12 months of PITIA.
FAQ
Can you get a home equity loan on a houseboat? Almost never. A houseboat is vessel collateral and routes to a marine lender.
What’s the difference between a houseboat and a floating home for lenders? A houseboat has or can carry propulsion and is titled as a vessel. A floating home has no engine, sits on a permanent float with hard-connected utilities, and in Washington and California is treated as real property for lien and tax purposes.
Will Fannie Mae or FHA finance a floating home? No. Both are ineligible. VA guarantees don’t apply either.
Which banks finance floating homes in Seattle? Banner Bank and Sound Community Bank run active portfolio programs for Lake Union and Portage Bay. Confirm program status within 30 days of application.
Which lenders finance floating homes in Sausalito? Bank of Marin lends up to $1,000,000 on eligible one-unit homes with concrete hulls in Sausalito and Richardson Bay.
Can you get a HELOC on a floating home? Rare. Portfolio lenders generally offer cash-out refinance or fixed home equity loan structures, not true revolving HELOCs, on floating-home collateral.
Is houseboat loan interest tax deductible under IRS Pub 936? It can be if the boat has sleeping, cooking and toilet facilities, the debt is secured by the vessel, and the proceeds meet the acquisition-debt tracing rule. Consult a tax professional.
What LTV can you get on a floating home in 2026? 70% to 80% CLTV where real-property treatment applies, 65% to 75% in personal-property states.
Does a floating home need a marine survey instead of an appraisal? Yes. Portfolio lenders require a current marine survey and hull inspection in place of a traditional appraisal.
Why do lenders care about moorage lease remaining term? Because a moorage lease shorter than the loan term leaves the collateral valueless before the loan amortizes. The 20-year floor is the common cutoff.
Can I use a HELOC on my regular house to pay off my houseboat? Yes, and this is often the lowest-cost route. A standard HELOC on a land-based primary residence closes at conforming rates and sidesteps the portfolio-lender problem.
Can you refinance a houseboat to pull cash out? Yes, as a marine refinance written against the vessel. Rates and terms match the marine loan market rather than the mortgage market.
