What are today's underutilized strategies and areas?

[Charles Worth]

With the huge surge of interest in real estate investing by new and experienced investors, the return of home buyers to market and the resulting rise in prices I was curious to see what the community thought were today’s underutilized strategies and areas (cities, towns, states even blocks) that could be interesting in the next 6 months and are not yet popular enough to be something most people know about and are thus using thereby driving up prices as well as reducing supply.
