Assumable mortgages in Fairfax, Virginia — take over a 3% loan.
Fairfax County is Virginia's largest — and scale is an edge when you are hunting assumable loans. A huge stock of homes carries FHA and VA loans originated at 2–4% in the 2020–2022 low-rate window, and assumability never shows up in an MLS listing, so off-market parcel intel is the only way to find them. shinnslist already watches all 369,419 Fairfax parcels with live data from the county's own gispub2 GIS parcel service. The honest gap, stated up front: this layer carries parcel identity (PIN, parcel type, polygon geometry) — owner names, assessed values and street addresses are phase-2 joins, never invented.

Why assumable still wins here
The math does not care about the zip code. Millions of homeowners locked FHA and VA loans between 2% and 4% in the 2020–2022 window; market rates sit near 7%. On a $300,000 loan, assuming 3.25% instead of borrowing at 7% keeps roughly $690/month in your pocket — about $82,800 over ten years. One rate difference, one purchase, the deal is made the day you buy. You make the money on the purchase — never count on making it on the sale.
FHA and VA loans are generally assumable by design; most conventional loans are not. And the loan never shows up in a listing — which is why off-market parcel intel is the edge, not a prettier search of the same MLS.

This page is educational, not financial or legal advice. Loan assumability depends on the specific loan, servicer, and buyer qualification — FHA and VA assumptions still require lender approval. Parcel counts above are the engine's verified live ingestion state (sources: FAIRFAX-INGESTION.md in docs/), checked 2026-09-29; flagged-loan candidate counts are marked [DEMO] until the loan-fingerprinting signal layer is ingested. Always verify loan terms with the servicer before making an offer.
