The market here in San Antonio is desirable for a few reasons. Just a little insight into the town here:
This has been traditionally a military town with a few major local basis within the city limits. We're home to the San Antonio Spurs NBA franchise (5 chips, don't hate), a great Mexican American culture with the old missions spread throughout the city (Remember The Alamo!!!), terrific food and night life, and really great outdoor things to do both within the city and just outside the city in neighboring towns. Like other major cities, there are a lot of opportunities for all types of investors but naturally you'll develop a sweet spot for yourself.
Some pockets of the city are more attractive to out of state buy and hold investors than others and I think it mostly breaks down to the same basic things. The out of state investors I work with typically try to avoid areas of town with subdivisions dominated by older homes. These homes, although can be bought on bigger discount in some cases, typically come with larger rehabs that out of state investors don't want to manage from so far away. The consensus for my out of state investors is to locate homes that are not as old and not in too bad of shape. I mostly deal in off-market distressed deals that need fixing up before making it a rental or selling so a key thing my out of state investors look for is having good teams in place to handle the rehab. Networking here on BP, on local GC Facebook boards, and with local pros to utilize their contacts are good ways to go about putting this side of your team together. Always do your diligence.
The competition for the turn-key, great location, good condition, 3 bed, 2 bath deal on discount here is too much for many of the out of state investors - they just don't have the ability to move fast enough. In some cases you'd have to buy sight unseen which without a team in place and a great amount of experience I would not recommend. Giving yourself the best competitive advantage by having your ducks in a row in advance of having deals pitched to you is a HUGE plus. This is likely the first step. Network with pros, property managers, contractors, agents, finance guys, etc etc. Pick their brains about areas, recent projects they've done, current rentals they own, and any bad experiences they've had in the past. A lot can be learned from others' mistakes.
Have a plan and share your plan with your team so that they can be on the same page with you as the right opportunities become available. If everyone in your team has an aligned interest in your investing success and the proper diligence is done, San Antonio can facilitate your goals both in the short-term and long-term. I'm sure as others will chime in you'll see similar ideas and other unique ideas. But it seems like you've done a lot of homework and I commend your drive to get going. Best of luck!
