What buyers should know
Foundation and drainage: the Blackland Prairie expansive clay beneath McKinney expands when wet and contracts in drought, shifting slabs and cracking supply lines; budget for a structural inspection and plan for consistent perimeter watering year-round.
Special districts: new-construction communities — especially master-planned developments like Trinity Falls — often carry a MUD tax or PID assessment on top of normal property taxes; request disclosure documents and check the city's Special Financing Districts map for any address you are considering.
School district boundaries: five different ISDs serve McKinney addresses, and the boundary does not always match subdivision marketing materials — verify the specific parcel's district assignment through the city's School Zones page or Collin CAD before making enrollment plans.
