Dallas vs SA vs Houston

[Kenneth McKeown]

Hey all! I've been active for the past 6 months on this forum and nearly had a few first investment purchases work out... but I ended up resigning from the current job at (teaching) to pursue other options. This has halted my ability get approved for a mortgage loan - but I look to purchase immediately as soon as I get an offer for the next school year. 

My question is what are your thoughts on these three major cities? I'm pretty familiar with the business in San Antonio, having lived here the past year and am in the midst of getting my real estate license as we speak, but was curious if Dallas or Houston would be potentially decent cities to invest in as well if a job took me in that direction. Any thoughts would be great! You can also comment on which cities would be best to become an agent in as well - as that's my goal in a year or two is to transition from a full time teacher + part time realtor to a full time realtor. Thanks!
