For your first deal, I would reconsider your home town of Houston. I currently live in Lubbock and own 4 SFR's - 2 in town and 2 long distance. The long distance ones aren't bad now, because of one thing - I have an incredible property manager, which I would recommend using a property manager regardless of where you buy for your first deal. I went on my own for my first 2 houses and lost A LOT of money by making stupid mistakes (trying to save a buck). Work in property management fees into your analysis and don't think twice about it - be aggressive and plan on paying a fee of 1 months rent + 10% of the monthly rental charge. If it's less, great!
I don't necessarily have a problem with long-distance purchasing, but I personally wouldn't be comfortable with that being my first deal, especially if you live in Texas. Regardless of where you buy, first find your property manager and realtor who is used to dealing with investment properties - the realtor can usually recommend a good property manager.
I am definitely NOT a guru, but I love having consistent repeatable base hits. Most hall-of-fame baseball players didn't get there by belting home runs every time they went to bat. Consistent base hits generating a few hundred per month start to add up fast. I am really wanting to do the BRRRR strategy, but I'm building up my cash position so I can do my first one soon. I have a few friends using the strategy and they LOVE it!
Bottom line is that it depends on what you want as an investor AND what you significant other wants. My wife is on-board as long as, as she says, "if it's a place I would live if the sh*t hits the fan, then okay". That's her criteria and if that is what it takes for her to bless the deal, so be it! That also affords a higher quality house and higher quality tenant.
