Of course you take govt programs.

The loan programs of your buyers will dictate how much of a credit you are allowed to apply to their closing but it certainly helps to move inventory when you offer an incentive. 

The naca program will permit single home Duplex , triplex , four plex  so you can live with your wife in one town house and rent the rest 

So don't leave anything in an MTR that is irreplaceable.In addition to security deposits, you can also use the AirCover program for Airbnb bookings and third party services like Waivo and Safely that provide mini insurance per booking.

@Joseph Pelensky It does not appear you will have the required closing costs needed to purchase a $700K building through a refinance or sale of your $285K duplex.

City National Bank has a $50K grant program for homes in certain neighborhoods.

Now appears to be the start of a tipping point where people want to sell, but there aren't many buyers.

Have you had any experience working with Section 8 tenants/programs?  

On the face of things it appears you will have a hard time getting a +10% ConC return.

My opinion is that Zillow appears to be the most accurate but I don't know if it depends on the area meaning maybe in another area, Rentcast or Rentometer may be more accurate.
