MTRs in Texas - locations for new construction units

[Richard W.]

I'm a small scale developer of new construction units in Texas (so far duplexes in Dallas and a 5-unit townhome project in Houston). Rather than always sell when complete I'd like to keep some units as MTRs. I like building in areas with greater appreciation potential (hence lower cashflow), and don't want to make the time commitment to manage STRs. Hence MTRs may fit well.

I'd be open to building anywhere in Texas, although Dallas and Houston are obviously easier. Any advice on specific locations and/or a methodology for narrowing down the locations would be much appreciated!
