Hey can you please provide a name of a town(s) or lakes in east TN.
It all depends on what you're looking for in retirement.
West Knoxville is nice in a mid size college town, and I understand the Tennessee River west and south of there is incredibly beautiful and the waterfront houses are simply stunning. Loudon, TN and the Little Tennessee River have a bunch of waterfront resort communities.
North of Knoxville is Norris Lake--with 18 marinas, condos and the lake is simply immense. I's very beautiful water and a fine fishing lake.
East of Knoxville is Douglas Lake, with Dandridge, Sevierville, Pigeon Forge and Gatlinburg close by. Living here brings major Smoky Mountain vistas. Pigeon Forge/Gatlinburg have bunches of condos, as they're resort towns.
A little farther northeast, you'll find Morristown, Greenville and Jonesborough--all cities with very nice societies and lifestyles. Housing costs are low.
45% of the population of Johnson City is from elsewhere, and they refuse to leave after living there. It's got East TN State University and a medical school--good culture and a youthful population.
My sister lives 1/2 time in Banner-Elk, North Carolina on a Jack Nicklas Golf Course in an equestrian community. It's expensive real estate, but they have a neighborhood 4600' runway and the highest two ski slopes on the East Coast (Beech Mountain and Sugar Mountain resorts.) It's hard to beat it as a retirement location.
But what the region has is real people, including authentic hillbillies. The locals are quick to laugh, tell a joke and it's a very happy, safe place to live.
