Estimate only, not a loan offer or quote. Principal and interest use the Freddie Mac 30-year fixed average of 7.03% (week of Sep 24, 2026); your rate will differ. A loan this size is typically a jumbo loan, which prices differently. Tax and insurance are modelled, not billed amounts; tax uses a typical Costa Mesa rate, excluding Mello-Roos. Verify all figures. Full assumptions and disclosures.
