The walkability and safety of the city’s tree-lined streets, zealously patrolled by the town’s police force. And, of course, the private-school-quality education at public-school prices that Highland Park ISD provides its students.

Lot value so far outstrips the structural value of most of the original homes that buyers often feel they have no choice but to tear down the old and put up something new and much bigger. This has made both McMansions and narrow streets clogged by construction equipment an increasingly frequent sight.

The western edge of Highland Park falls outside the boundaries of the Highland Park school district, which is why you’ll see home prices drop significantly from one side of the Dallas North Tollway to the other. Still ain’t cheap.
