How to finance an ADU? How other people pay for ADU?
We could mention a bunch of ways for ADU financing: which one you use – depends on you, your situation, your accountant and financial advisor. There is no one answer that fits all.
Take your pick between any one or any combination of cash and credit cards, cash-out refinance and home equity line of credit (a.k.a. HELOC), construction or renovation loan, borrowing from a retirement account or from friends and family, reverse mortgage loan or shared equity financing. The list goes on. There is even an option to get structured funding from an investor, or even friends and family though a Rent Sharing Loan.
We know, the companies on this page assist homeowners with ADU projects. Each has a different approach to financing. Figure out what works best for you depending on your personal situation, equity in the main house and monthly cashflow. Or consult a mortgage broker to assist you. Most importantly, shop around. Interest rates and closing costs differ.
Below are some options that may help you – provided for educational purposes, we are not receiving any commissions from these companies.
