@Daniel LaMontagne... @Andrew Johnson is pretty accurate in saying that dirt appreciation is limited to the "core" areas... I'll detail it a bit more just to keep us all on the same page... I view the 2 cores in NWA as the University of Arkansas and downtown Bentonville/WM Home Office. These are areas where some of the appreciation we are seeing currently will continue and maintain (it's where the money is)... Just to note on a quick exception, housing in DT Bentonville cannot continue to demand $200+ /sqft long term, just sayin'.
Then you have working class cities like Rogers and Springdale where a lot of blue collar folks live and need affordable housing... You won't see the appreciation in these areas continue very long because wage rates for the hourly folks are not following the same upward path and that will naturally keep the balance.
If I had the money and the time, I'd be looking at Tulsa first, then over to Ft Smith... 2-3 years ago would have been the time to jump on NWA property, now with the inventory level about to correct and values WAY over what they should be caution is highly advised.
