Rental property near affordable, mixed income housing?

[Raymond Shoe]

Hi All,

I am new to real estate and would love to get some advice. I am considering purchasing some single family homes in durham NC but have learned there will be plans to develop a 740 unit "affordable, mixed income properties" with retail space within a block of it. The area is currently undergoing transition. Here is a link to the units being developed.

Do these "affordable, mixed income" properties typically increase or decrease surrounding property value? Will these additional units make it harder to rent my property?

Thanks for any input!
