Financing your ADU in Beverly Hills
Most Beverly Hills homeowners compare renovation loans, construction loans, HELOCs, and cash-out refinancing. ADU-focused lenders can underwrite against after-build value when the new unit materially increases rent or resale potential.
Construction / renovation loan
Funds released in draws as the build hits milestones; underwritten against after-build value.
HELOC / home equity
Borrow against existing equity. Fast to set up if you have 20%+ equity.
Cash-out refinance
Replace your mortgage and pull equity as cash — best when rates are favorable.
ADU-specific lenders
RenoFi and similar lenders underwrite the projected value the ADU adds, often unlocking more.
