Records to check before you buy in Marion County

• Property record card — the Marion 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 Indianapolis; the official county website is the reliable route to the parcel search and the office directory.
• Deeds & liens — the Marion 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. Marion County is the primary county for 36 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 Marion County reported 41,118 offenses — 41.89 per 1,000 residents; the largest single category was larceny-theft (20,126). 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 Marion 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 Indianapolis.
• School assignment — the district office, not the listing. Only the district's own boundary lookup confirms which school an address is actually zoned for.
