Most Williamson County buyers qualify for at least one TSAHC or TDHCA program; the county is not designated a HUD targeted area, so the standard income limits and first-time-buyer rules apply.

Property tax in Williamson County averages around 2.04% effective (verify current year at the county appraisal district). The Texas residence homestead exemption shaves $100,000 off school-district appraised value and caps appraised value growth at 10% per year — the single highest-return paperwork move a new homeowner makes. File on or before April 30 of the year following purchase.
