I live in a high cost area (SF Bay Area) in a 110-year-old home with many features that would not be included in the typical home used for ballpark new construction cost estimates (wood floors with inlays, built-in cabinetry, wood frame windows, etc.). If my house burned to the ground the cost to rebuild a house with similar finishes and up to current code would be significant.
How can I find good data for estimating the replacement cost of my home? My insurer provides estimates but I’d like to double check that their estimates don’t leave me underinsured.
