ADU construction in Twin Falls typically ranges from $80,000 to $350,000+. We help you understand your options, compare programs, and connect with lenders — so you can invest with confidence.
How We Help with Financing
We're not financial advisors — we're ADU builders. But we know that financing is one of the biggest questions homeowners face, and we've helped dozens of clients navigate their options.
As part of every Feasibility Check, you receive a personalized financing options checklist tailored to your project budget, your equity situation, and your goals. We also connect you with local lenders who specialize in ADU and construction financing.
Common ADU Financing Options
HELOC (Home Equity Line of Credit)
Borrow against your existing home equity with a flexible draw period. Draw funds as needed during construction and make interest-only payments during the draw phase.
Best for:
- • Homeowners with significant equity (typically 20%+)
- • Projects where you want flexible draw timing
- • Lower upfront costs vs construction loans
Key details:
- • Faster approval than construction loans
- • Variable interest rates (typically)
- • Potential tax deductions (consult advisor)
Construction Loan
Purpose-built for building projects. Funds are released in stages (draws) as construction hits milestones, then the loan converts to a permanent mortgage when the project is complete.
Best for:
- • Homeowners without enough equity for a HELOC
- • Larger projects ($200K+)
- • Those who want milestone-based funding
Key details:
- • Lender oversight keeps project on track
- • Converts to permanent mortgage on completion
- • Requires approved plans and contractor
Cash-Out Refinance
Refinance your existing mortgage for a higher amount and use the difference for ADU construction. Can be advantageous if current mortgage rates are favorable.
Best for:
- • Homeowners with high equity and favorable rates
- • Those who want one simple monthly payment
Key details:
- • Fixed rate available (vs HELOC variable)
- • Replaces existing mortgage entirely
Cash / Savings
If you can fund part or all of your ADU with cash, you avoid interest costs entirely. Some clients use a combination — cash for the first portion and a smaller HELOC for the rest.
