Low demand/undesirable areas=low prices.

I’ve always heard to stay away from these types of properties, because they are undesirable to tenants.

A vacant unit that looks like crap (however undesirable) is still better than the condo project being disqualified for borrowing. 

Both have a high ratio of Section 8 tenants since both were undesirable prior to 2010 (I bought due to gentrification and being few areas that can still cash flow here).

Is the Congress Heights changing or still an undesirable area and any ideas on how to use the property other than moving in it. 

I have an undesirable unit which is not renting.

Is there something that makes this lot desirable or undesirable?

And yes, back about 30 years ago, here in LI New York, people are concerned with minorities moving into the neighborhood, and telling me be careful who you sell to, not criminals, is somewhat of a code word.Finally OP was asking about problems with assigning contracts in general, and my point was the assignor has no control over the property any more, and the property can be sold to criminals, or undesirables, or minorities.

Public transportation for mid-class working people seems to be mostly undesired, making the last point not as important IMO.

Inflated ARV's could create an undesirable scenario where the homeowner unexpectedly walks away with less than 20% equity.
