@Stephanie Ro My husband is military (27 years), so we've lived near our fair share of military bases! Right now, I live near Tinker AFB (in OKC area), and there are tons of rentals near bases for sure! There's good and bad about rentals near bases IMO.
Good - steady, good rents from military and their supporting civilian workers. You don't have to worry about evicting military members as much (not always true b/c people are still people, but definitely less likely).
Bad - If a base closes, and there is not enough employment beyond the base...your rental could be in real trouble. For larger metros (like OKC), this is less of a problem. But if the base is out in the middle of Oklahoma (like Altus, OK or Enid, OK) and (not saying they will b/c both bases have clear missions currently) but IF they did close... there aren't a lot of jobs to replace the jobs lost from the base closure....therefore renters might leave. So just use caution when selecting your military base, they are not all equal IMO.
