How to use this library
The Buyer Learn library is organized around the three questions that matter most during a home purchase: am I in a hazard zone, what will insurance cost, and what can I do about it. Every article is grounded in a federal data source, reviewed by an analyst before publication, and stamped with the date of last editorial review.
Start with the article that maps to your immediate uncertainty. If you are choosing between two properties, jump to the hazard-specific guide for your region — flood for coastal, wildfire for the West, hurricane for the Gulf and Atlantic seaboard, earthquake for California and the Pacific Northwest. If you are relocating, start with the city and state libraries to compare market-level signals.
We are adding new articles every month. If there is a topic you would like to see covered, email hello@riskbeforebuy.com.

Common buyer questions
Where should I start?
If you are early in the home-buying process, run a free address snapshot on the property you are evaluating. It returns the FEMA flood zone, county-level composite, and top three hazard flags in seconds. If a property looks interesting, escalate to a $19 full report before going under contract.
How do I know if a 'Top 20% nationally' score is bad?
The percentile phrase is calibrated against the entire US county distribution. 'Top 20% nationally' means the county is riskier than 80% of US counties — material context for insurance cost, resale, and long-term livability. Pair the phrase with the per-hazard breakdown before deciding.
Why is my agent surprised by these numbers?
Most agents are not trained to read FEMA NRI, USDA wildfire, or USGS seismic data. Our value is precisely the translation layer: federal data into a brief that fits in a 10-minute conversation.
How often do you update?
FEMA NRI, USDA Wildfire Risk, and EPA EJScreen are refreshed on a 90-day cadence. NOAA Storm Events updates continuously. USGS Design Maps is queried on demand at lookup time. The retrieval timestamp is stamped on every score.
