Numbers you can check.

Every assumption in these is visible and editable. They account for the things that make Southern California different — Prop 13 reassessment at your purchase price, Mello-Roos, the $750,000 mortgage-interest cap, an insurance market that has gotten hard, and jumbo thresholds that arrive earlier here than almost anywhere.

How these are built

They don't flatter buying.

Most real estate calculators are lead magnets. Default assumptions get chosen so the answer comes out "buy now," and a form appears.

These use conservative defaults and show their work. The rent-vs-buy tool will tell you, when it's true, that buying takes a long time to pull ahead of renting and investing the difference — and it shows you exactly which assumptions drive that.

No signup, no email gate, no results held back behind a form.
