The Bottom Line

AvoidWilliamson may be challenging for traditional rentals. High prices or low rents make cash flow difficult.

Williamson County in Tennessee scores 36/100, ranking #766 of 1,000 US counties (top 98%). At 20% down and current rates, a median-priced rental loses about $3491/month; the 2.74% gross rent-to-price ratio doesn't survive debt service. The thesis here is appreciation, value-add, house hacking, or all-cash.
