With the information you have given I would agree that you should consider doing it, in fact, I have recommended several people moving to Wright-Patterson AFB to consider buying in that area, as the property price to rent is quite attractive.

Per the OP's numbers, that still does not look attractive.

If your finances / credit are a shambles and your current income isn't helping you sort it out,     then obviously you need to focus on gaining more income.Set your financial issues aside for now - they're not helping you - and learn to work around them.One of the biggest newbie mistakes is thinking that you need your own money and sterling credit to get into REI.While those certainly do help, if you don't have them, you need to find a different solution.Learn to attract and engage private lenders.Folks with large retirement accounts - medical people, attorneys, ... high-income professionals who may or may not be self-employed - need alternatives to the risks, whims and paltry ROI of Wall Street.

If I were renting your place I would want it near other tourist draws like Fredericksburg wineries and shopping or the Guadalupe river or a ranch that does guided trail rides. 

I've read there is a record number of new apartments coming online in 2nd half of 2019 which is concerning (50% of which is located in downtown Cleveland) as, it would seem to me, that these new properties will provide steep competition for renters and make existing older buildings less attractive places to rent (driving vacancy up and rents downward).

I see some really attractive travertine at the box store but wonder how hard that is to keep the pores clean??? 

The least desirable houses will always fill last, and cannot attract more tenants by lowering their pricing.

Know Your Product, Know Your AudienceAdditionally, knowing that intown buyers, loft buyers and Millenials are very attracted to the modern style of their furnishings, this location made perfect sense.  

Est 233 ,, divide by 4 = about 58 each.. hard to compare the duplex you didn't include price,, so ya do the math but personally I put my efforts towards the 4 plex.Honestly if the guy is 100% rented and his rents are close to market you can figure the interiors command that price and are probably pretty decent.YOu can start this property and do very little until you have a vacancy, and then decide what you want to rehab, otherwise  your set, and can do some exterior, yard and common area fixes first which will attract and warrant rent increases to current units.

Atlanta REIA is good for networking but it attracts a lot of hustlers so be careful.
