Common questions

Things people ask first.

I'm a tech worker with mostly RSUs and cash — can I actually qualify?

Almost certainly yes. We work with 3–4 lenders who specialize in equity-comp buyers and use vested-RSU income, bonus history, and ADU rental projections to expand your purchase power. Most clients are surprised how much they qualify for.
