My recommendation would be to plan to achieve a diversified portfolio across sponsors, geographical areas and asset classes. 

You are comparing to large geographic areas. 

The question of how soon, the answer is much sooner than any of us wish to believe, As humans expand into new territories both geographic and genetic. 

@Rama MulpuriFYI On a geographic simplistic approach, the closer you are to I-45 in RR and to I-35 in Pflugerville, the better you’ll be.

A good place to start your search if you're not sure what area of the country you want to invest in• BiggerPockets Deal Finder (on market)- once you have an area or two in mind this is like using zillow on steroids because it has investor specific filters and does some of the analysis for you for example you can filter by rental yield and it will also show you homes that analysis shows are underpriced for their market• BiggerPockets Deal Finder (off market) - Maybe not best for your first deal based on your description of your current status and goals but helpful if in the future you want something that you can force appreciation, most of these homes are in foreclosure • BiggerPockets Calculators - as a BP free member you get up to 5 uses of the calculators free every year, as a pro member you get unlimited uses of all the calculators, and you can save each analysis you run so you don't have to come back and redo it every time.

You could consider posting on LoopNet as that is geared towards investors.I would also look at the photos, description, etc.

I wont go into descriptions besides that the pictures were pretty gross , shockingly gross .
