# Florida Homestead Integrity File: free sample (Tensorust LLC)

50,859 Florida 2026 homesteads with conflicting signals, $10,971,605,911 of exempt and capped value, county by county.

**Headline:** A Florida owner can hold one homestead, yet 50,859 of the 5,018,787 homestead parcels on the 2026 NAL rolls of 59 counties carry a conflicting signal: the same owner and mailing address on two or more homesteads, a tax notice mailed out of state, or a business entity as owner.

This repository is a **free teaser**, not the dataset. It holds 25 example rows and a summary table with no names in it. The full file has **50,859 rows** and is sold by Tensorust LLC: **[https://tensorust.com/datasets/fl-homestead-integrity/](https://tensorust.com/datasets/fl-homestead-integrity/)**.

Email **mattbusel@tensorust.com** with the tier and a billing contact, and we will send a proper invoice (ACH or card). The file is delivered once the invoice is paid. Details and the live sample: [https://tensorust.com/datasets/fl-homestead-integrity/](https://tensorust.com/datasets/fl-homestead-integrity/). All datasets: https://tensorust.com/datasets/

## Method and limits

Homestead = EXMPT_01 > 0. Owner names and mailing addresses are normalized (letters and digits, ZIP5). A multi-claim group is one owner name and mailing address carrying homesteads at 2+ situs addresses statewide. Entity owners exclude trusts and life estates, which can hold a homestead. Tax uses a flat 1.6% average millage and is labeled an estimate.

Not a finding of fraud or ineligibility: each flag is a reason for the appraiser to review. Never published or sold to anyone but the deciding county appraiser; no names in the sample or on the site. Not for qui tam or private enforcement use. Tax figures are estimates at an average millage.
