Financing Options For Adus

Financing an ADU construction is no small feat it’s a significant investment need that homeowners often need to strategize for. Typical financing options include savings home equity loans and loans specifically designed for renovations like the RenoFi Renovation Loan.

In an in-demand region like California where high rental rates and steep real estate prices have driven ADU popularity choosing high-quality finishes can result in a higher rental income return on investment.

Therefore it is crucial to consider the potential financial benefit of your ADU and plan your budget accordingly especially considering decorating furniture cost and other finishing stages of the project.
