01 · The RealityMost of our buyers pay cash or use a HELOC.

Here's the honest truth about financing park models, container homes, and small ADUs: traditional 30-year mortgages generally don't apply. Because our homes are compact — under 400 square feet in most cases — and often built on chassis or wheels, they typically don't qualify for the standard mortgage products you'd use on a site-built house.

The good news: most of our buyers already have a path. Cash, home equity lines of credit, and personal loans are the most common ways people finance these builds. For larger custom or commercial projects on permanent foundations, additional options open up — but for the compact models we sell most often, plan on one of the paths below.

The short version

Small park model / ADU / container = cash, HELOC, or personal / RV loan. Larger custom builds on permanent foundation = may qualify for construction loans through local lenders.

02 · Common PathsHow buyers actually pay for these.

In our experience, buyers land on one of these routes — often combining two or more:

  • CashThe simplest route. A significant share of our buyers pay from savings, an inheritance, land sale proceeds, or investment accounts.
  • Home Equity Line of Credit (HELOC)If you already own property with equity, this is usually the cleanest financing option. Rates are typically better than personal loans, and you can draw against it as you need funds during the build.
  • Cash-out refinanceSimilar to a HELOC — pulling equity from a home you already own to fund the build.
  • Personal loansUnsecured personal loans from banks, credit unions, or online lenders. Higher rates than a HELOC but faster to close and no property required as collateral.
  • Park model / RV loansSpecialty lenders finance park models and RVs as personal property. Terms are typically 10–20 years with higher rates than a mortgage but lower rates than an unsecured personal loan.
  • Contractor / builder financingSome regional lenders and credit unions have specific programs for small home and ADU builds — worth asking about locally.

03 · Specialty LendersFast financing built for our type of home.

A handful of national lenders specialize in financing park models, tiny homes, and ADU builds — the kinds of homes that don't fit traditional mortgage products. Two we've seen buyers use successfully:

LightStream (a division of Truist Bank)

Loan amounts: $5,000 to $100,000  ·  Type: Unsecured personal loan

LightStream is an online consumer lender that offers fixed-rate personal loans specifically usable for tiny home, park model, and ADU builds. Because the loan is unsecured, you don't need an appraisal, home equity, or land ownership. Good-to-excellent credit is required for the best rates. No fees, no prepayment penalties, and funds can arrive as fast as the same business day for approved applicants.

Buildertrend Financing (powered by Nelnet Bank)

Loan amounts: $3,500 to $150,000  ·  Rates: Fixed APR (rates vary; contact for current terms)  ·  Terms: Up to 15 years

A newer financing option built specifically for prefab and modular builds. Higher loan cap than LightStream ($150K vs. $100K) makes it a strong fit for our full-priced park model builds. No application fees or prepayment penalties. Unlike LightStream, which you apply for directly, Buildertrend Financing is offered through your builder — so contact us if you'd like to explore this option and we'll get you into the application process. Applications are online, and decisions typically come back in minutes.

Which is right for you? LightStream tends to be faster and simpler for smaller builds under $100K. Buildertrend/Nelnet is often better for full-priced builds because of the higher cap and longer terms. Both are third-party lenders — Wolf Den doesn't originate or service either loan. We're happy to talk through which might fit your situation before you apply.

04 · Container HomesContainer homes are trickier. We'll tell you that upfront.

Container home financing is genuinely harder than modular. Traditional lenders often treat container homes as non-standard construction, and appraisers struggle to find comparable sales in rural areas. Common paths for our container buyers:

  • CashStill the most common path for our smaller container builds.
  • HELOCsIf you already own property with equity, this is usually the simplest financing route.
  • Specialized container-home lendersA small number of lenders work specifically in this space. Terms and rates vary widely — worth shopping around.
  • Personal loansFor smaller builds or to cover gaps on larger projects.

Plan on a larger down payment, more documentation, and a lender who has actually financed a container home before. We can point you toward ones who have.

05 · What You'll NeedThe basics lenders will ask about.

Different loan types have different requirements, but most lenders (whether HELOC, personal loan, or specialty park model lender) will look at:

  • Credit score620+ opens most doors. 680+ gets you better rates and easier approvals.
  • Down payment or equityCash buyers put down the full amount. HELOC borrowers use existing home equity. Park model / RV loans typically require 10–20% down.
  • A site planEven for cash or HELOC purchases, you'll need to know where the home is going — including local zoning and permitting.
  • Utility hookupsPower, water, septic or sewer. Off-grid setups are possible but affect financing and resale.
  • Debt-to-income ratioMost lenders look for DTI below 43% on secured loans, sometimes 50% on personal loans.
  • Proof of income and assetsStandard documentation — pay stubs, tax returns, bank statements.

06 · Regional LendersLocal banks and credit unions who know these markets.

National online lenders often don't understand Alaska construction realities or Pacific barge logistics. Local lenders do. A few worth talking to:

  • Global Credit UnionFormerly Alaska USA Federal Credit Union. Alaska-headquartered credit union with branches across Alaska, Washington, and the West.
  • Denali State BankAlaska-based bank familiar with in-state construction realities.
  • Mt. McKinley BankFairbanks-headquartered, well-versed in Interior Alaska builds.

For larger custom or commercial builds on permanent foundations, some of these lenders also offer construction loans that convert to standard mortgages. That's a conversation to have with them directly once you know the size and site of your build.

Tell us about your project.

Financing a park model, container home, or small ADU depends on your location, the home type, and whether you already own property to use as collateral. We're not a lender and we don't take a cut of your loan — but we've worked with enough buyers across our regions to point you toward the right path for your situation.

Share a few details and we'll send you a short list of lenders worth talking to, based on where you're building and what you're building.
