These facts are for the listing's map point, which can sit off the lot. A zone line can also cross a lot, and agencies revise their maps. In cities, the fire zone line follows the State Fire Marshal's 2025 map; each city adopts its own map and may add areas. These lines are not a Natural Hazard Disclosure. Check the official maps and the seller's disclosures before you rely on them.

Estimate only, not a loan offer or quote. Principal and interest use the Freddie Mac 30-year fixed average of 7.24% (week of Oct 29, 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 Orange County rate. Verify all figures.
