Two federal datasets, joined honestly

Everything published here comes from named public sources, with the crosswalk between them documented in full.

Real tax burden

Median property tax paid and median home value from the Census ACS, at ZIP code tabulation area grain, each with the margin of error the survey publishes.

Federal hazard ratings

Composite risk plus inland and coastal flooding, wildfire, hurricane, strong wind and tornado, taken from the FEMA National Risk Index.

An honest crosswalk

ZIP code areas do not nest inside counties. 30% span more than one, so ratings are apportioned from census tracts and weighted by population.

Nothing invented

No insurance premiums, no flood zones, no forecasts. No free authoritative source for those exists, so this site does not publish them.

Frequently Asked Questions

How to determine property tax by ZIP code?
You can determine the median property tax for any US ZIP code using our free lookup tool. We aggregate the latest Census American Community Survey (ACS) data to provide median tax paid and effective property tax rates by location.
Is my address in a FEMA flood zone?
While we provide the FEMA National Risk Index for broader ZIP code areas, determining the exact flood zone for a specific address requires consulting the official FEMA Flood Map Service Center. However, our ZIP code analysis gives you a high-level view of flood hazard ratings in your desired neighborhood.
How do I find out what my property taxes will be?
Property taxes depend on your home's assessed value and the local tax rate. You can estimate your future tax bill by finding the effective tax rate for your ZIP code on our site and multiplying it by your target home price.
What is my property tax rate by ZIP code?
Effective property tax rates vary significantly across the US, even within the same county. Search for your ZIP code on Zip Cost Ledger to see the local effective rate, calculated from census data of actual tax burdens relative to home values.
What does a FEMA flood zone X mean?
FEMA Flood Zone X represents areas of moderate to minimal flood hazard. It's usually outside the Special Flood Hazard Area (SFHA), meaning flood insurance is generally not federally required, though the risk of flooding is not entirely eliminated.
What is a property risk assessment?
A property risk assessment evaluates a location's vulnerability to hazards like floods, wildfires, hurricanes, and tornadoes. We use the FEMA National Risk Index to provide these assessments, helping homeowners and investors understand the natural disaster risks associated with a ZIP code before buying.
