Records to check before you buy in Sullivan County

  • Property record card — the Sullivan County assessor / appraisal office. Pull the parcel's assessed-value history, exemption status, and last sale. This is the file your future tax bill is calculated from, and it shows whether the current owner is enjoying exemptions you will not inherit. County government sits in Blountville; the official county website is the reliable route to the parcel search and the office directory.
  • Deeds & liens — the Sullivan County recorder / land-records office. Read the deed chain, open liens, easements, and plat maps — the file a listing never mentions.
  • Official flood determination. Check the exact parcel on FEMA's National Flood Hazard Layer — not the listing site's licensed model. Zone boundaries cut through streets; the house next door can be in a different zone. Sullivan County is the primary county for 8 ZIP codes in the Census Bureau's ZIP-to-county crosswalk — and zone lines ignore every one of them.
  • The county's reported-crime record. In the FBI's 2024 file, agencies in Sullivan County reported 3,615 offenses — 22.22 per 1,000 residents; the largest single category was larceny-theft (2,265). The crime section below sets that beside the Tennessee county median.
  • Registry check. Run the address through Tennessee Sex Offender Registry (Tennessee Bureau of Investigation) and note the counts within a mile — then check again the week you close.
  • Permits & code history — the Sullivan building department. Open permits, expired permits, and code cases tell you whether the renovation in the photos was ever inspected. County permitting is run out of Blountville.
  • School assignment — the district office, not the listing. Only the district's own boundary lookup confirms which school an address is actually zoned for.

Coverage: 7 of 7 law-enforcement agencies assigned to this county reported at least one month of 2024 offense data to the FBI; 6 reported all 12 months. Counts are reported offenses only (FBI Return A / Arson master files), assigned whole to each agency's primary county; they are not adjusted for non-reporting agencies.

These are offenses reported to law enforcement — not convictions, and not a verdict on any street or address. A CurbFacts report pairs this county record with the ZIP-level picture for the specific address you are buying.
