Records to check before you buy in Lake County

  • Property record card — the Lake 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 Crown Point; the official county website is the reliable route to the parcel search and the office directory.
  • Deeds & liens — the Lake 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. Lake County is the primary county for 27 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 Lake County reported 9,817 offenses — 19.52 per 1,000 residents; the largest single category was larceny-theft (5,932). The crime section below sets that beside the Indiana county median.
  • Registry check. Run the address through Indiana Sex and Violent Offender Registry (Indiana Department of Correction, in partnership with Indiana county sheriffs (Indiana Sheriffs' Association)) and note the counts within a mile — then check again the week you close.
  • Permits & code history — the Lake 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 Crown Point.
  • 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: 21 of 21 law-enforcement agencies assigned to this county reported at least one month of 2024 offense data to the FBI; 17 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.
