The true cost of ownership
A listing shows you the price. We show you what it costs to own this exact address — the real tax rate from the county roll, any Mello-Roos or special assessments, insurance in its fire zone, and which utility sends the bill.

When you’re moving from out of the area, every listing looks like the same kind of number. It isn’t. Two homes at the same price can cost very different amounts to own — a special tax in a newer subdivision, a different utility, a fire zone that changes the insurance. HiddenHomeCost reads the county’s own records for the exact address, so you can compare towns you don’t know yet on the costs that actually come with the house.
Most of the county is SMUD territory. Newer master-planned neighborhoods in Folsom, Elk Grove and North Natomas often carry a Mello-Roos special tax.
Read the Sacramento County guide →Roseville runs its own electric utility; most of the rest is PG&E. Special taxes are common in newer Roseville, Rocklin and Lincoln subdivisions, and fire zones climb toward Auburn.
Read the Placer County guide →El Dorado Hills homes can carry two special taxes stacked on one bill. Foothill and Tahoe addresses bring wildfire-insurance and utility differences of their own.
Read the El Dorado County guide →Davis adds flat school, library and parks parcel taxes on top of the tax rate — real dollars a percentage never shows.
Read the Yolo County guide →Fire-zone status shapes insurance here more than almost anywhere in the state, and Gridley runs its own electric utility.
Read the Butte County guide →SCE and SoCalGas territory. A few coastal communities sit on leased land, with ground rent due on top of the mortgage.

The full picture, before you make an offer.
A few things worth knowing about any home you're considering — not to talk you out of it, but so the offer you make is the right one.
Mello-Roos
A special assessment common in newer communities. Worth knowing up front so you can compare homes on equal footing.
HOA dues
Not a public record — set privately by the association, not the county. We flag likely-HOA communities and show a sourced estimate where we have one.
Insurance outlook
Fire-zone status shapes what coverage looks like and what it costs — good to plan for, not to be surprised by.
Utility territory
Roseville Electric, SMUD, PG&E, SCE and Liberty Utilities at Tahoe all price differently. Knowing which one serves a home helps you budget accurately.
Solar
Owned, financed, leased, or a PPA all mean very different costs to you as the buyer — worth confirming before you assume it comes free with the house.
Supplemental tax bill
Buying resets the tax bill to your purchase price — separate from the 1% Prop 13 rate — and the county sends a one-time bill for the gap the year after you close.
