@Antonio Artusa I'm glad you have found a suitable group of tenants.

Most have 100+ residents if not 200+, and what, 2,3 visitor rooms.

We were shocked that there was such a steady stream of visitors in Columbus! 

To all in MA area:Subsidized voucher tenants are great for income and majority of them are great people who look after the property and let others enjoy it peacefully too.However, I heard that sometimes, someone who is not supposed to be living with the tenant, a boyfriend, girlfriend, just another relative, etc moves in with the tenant and starts creating trouble for other tenants and hence for the landlord too, by trashing the common area of the place.If we were to get a new tenant applicant with subsidiezed voucher, do landlords have any option, to treat them like other applicants, and, check their Credit History, Rental History and how clean they kept their previous accommodation or any other item that can be legal grounds to keep looking for more suitable tenant or should just accept to rent them because they came with the HA voucher ?

If you get multiple applications(with application fee) be sure to order them so you can process them until you find a suitable applicant. 

Then maybe go rent something in Bakersfield where all the dog breeders are or any  other suitable permitted location.

The completion of a parcel split request by the Office of the Property Appraiser is for assessment and taxation purposes only and does not establish or constitute a legal land division or in any way guarantees suitability for the parcel(s) to be developed at any future date.

I would take @Jonathan Greene's excellent advise, take advantage of the high market right now there and sell and find something more suitable as a rental property.

You find a suitable property for let's say $100,000 the seller owes the bank $75,000 how to we purchase the property?

Most Mortgagee are happy with a suitable bid at foreclosure auction so they do not receive the property back, as Rich mentioned above.
