Rural Home Check
Methodology

How the USDA precheck works

The calculator runs a deterministic first-pass workflow. It does not underwrite a loan or replace a USDA or lender decision.

Census Geocoder
1. Address to coordinates
A property address is sent from the server to the U.S. Census Geocoder using the current public address benchmark. The response supplies latitude, longitude, county, and state geography when the address matches.
USDA ArcGIS
2. Coordinates to USDA map signal
The coordinates are checked against USDA Rural Development's ArcGIS RHS SFH/MFH ineligible-area layer. A point inside a polygon is treated as likely ineligible for the property-location screen.
USDA limits
3. Household income to local limit
The tool compares annual household income with the FY 2025 Guaranteed Housing Program moderate-income limit snapshot. If a county row has not been ingested, the result labels that fallback instead of hiding it.
Planning estimate
4. Purchase scenario signal
Payment fit uses a standard 30-year principal-and-interest estimate plus taxes and insurance entered by the user. The ratio flags are planning guidance only.
Final property and borrower eligibility must be determined by USDA Rural Development and an approved lender after a complete application.

Match the method to a USDA question

Each scenario page starts from the same source chain and points back to the live precheck when an address or household-size detail is ready.
