I'd say mountain biker types and those transplants tend to be closer to Fayetteville and Eureka, or close to Little Rock. If one goes to other parts of NW Arkansas it's very slow there. It is true that towards Ft Smith and in Southwest Missouri Ozarks the market is slower.Northwest Arkansas real estate prices are hot because of mountain biking and the transplants from the left coast as well as Texas. I recommend Ft. Smith or anywhere Southwest Missouri.
Another good option is Ouachita mountains in West-Central AR. NW Arkansas real estate market had been heating up since a while ago, 2018-19, but nothing like Tennessee, prices are are better too
