Another pitfall is under improving properties in low income areas believing that since its a depressed area in terms of income the people will not have high standards. 

Over the last year and half they been sporadic with answering emails/calls and not on time with their scheduled owner payments and not getting monthly statements that show funds collected/expenses paid.

I’m a licensed realtor who found great success in the low interest rate boom and feel very fortunate for the happy clients I helped buy and sell and for the amount of them.

In your case properties appear to be fairly low value already, which suggests low demand and the potential to damage property values by building mfh there.

The condo doesn't have an elevator, but the other amenities are listed below:Amenities included: Common Grounds, Fitness Center, Gated, Reserved/Assigned ParkingServices included: Common Area Maintenance, Maintenance Structure, Insurance, Management, Pool(s), Recreation Facility, Reserve Funds, Snow Removal, Trash, Water, High Speed InternetThanks in advance for any advice!

Given the possibility of collecting was very low - I took the same approach as you, throwing good money after bad wasn't worth pursuing, so I sold at a big loss and chalked this one up as a big learning experience. 

Best and Safest Areas to Invest Near DallasWhen considering areas to invest in near Dallas, especially for house hacking, you'll want to look for neighborhoods that have strong growth potential, good schools, low crime rates, and amenities that attract renters.

Probably a noticeable low end look item to a potential renter.

The low entry price is tempting, but my opinion (usually unsolicited but not this time!) 

Especially if you have a mortgage or have ever commingled funds.
