ADU Financing Options: A Complete Guide

Building an ADU is a significant investment, but there are multiple financing options available to make your project affordable.

Home Equity Line of Credit (HELOC)

Pros:

• Flexible draw periods
• Interest-only payments during draw period
• Typically lower interest rates

Cons:

• Requires substantial home equity
• Variable interest rates
• Risk of foreclosure if unable to repay

Cash-Out Refinance

Replace your existing mortgage with a larger one and use the difference to fund your ADU.

Best for: Homeowners with low interest rates who want fixed-rate financing

FHA 203(k) Loan

Government-backed loan that combines home purchase and renovation costs.

Best for: First-time buyers planning to add an ADU

ADU-Specific Financing

Several lenders now offer specialized ADU financing programs with:

• Projected rental income consideration
• Streamlined approval process
• Competitive rates

ROI Considerations

Most ADUs generate $1,500-$2,500/month in rental income, with typical payback periods of 7-12 years.

Example: A $150,000 ADU generating $2,000/month = $24,000/year = 6.25-year payback
