For those of us on the left and right coasts, let me just ask...
You can buy a house for approx. $90K???? Holy crap. They are building townhouses near me that sell for $800K. You can get an older single family for maybe as low as in the high 400's if its a fixer upper. Most 2-3000 sq. ft. single families go for $600K and up to many millions. Townhouses from $400K to $1.5M (those 1.5M townhouses are fantastic though).
Anyway, that's just remarkable that you could buy a house for $90k or so.
Back on point, a few of the responses here may have been a bit off point by saying you've dodged a bullet. No one has asked, and you have not said, what's the intent of the investment? Hold it and hope for appreciation? Pos. cash flow? Hold it and be happy if there's neutral cash flow and though it's not appreciating, you are building equity because someone else is paying the mortgage? If the latter, than so what if you are even on the purchase price vs. the FMV. SteveNY's advice is good, but it's more focused on creating quick equity. Doesn't sound like the housing market down there in your part of TX is really hopping, so you may not be able to see quick growth and as we all know, bargains that are worthwhile are few and far between.
I'm just beginning my search for a commercial condo here in MD, so I can relate to the search.
