They can come to the table with cash to make up the difference.

These are park owned homes that generate really solid cash flow. 

I am not sure who you are using as your Realtor but I would reach out to a Anthony Wong who specializes in investment rentals or buyig the right primary that can be converted to a rental that will cash flow.

I would say it is on life support because after refi the negative cash flow necessitates extra reserves.

Another alternative that gives you quicker access to cash would be to borrow against it now.  

And finally (I personally despise this option) you offer cash for keys.

genuine cash flow.here's some good reading for you. 

Im located in Phx,Az and its common here to still see empty dirt land in prime areas of city, as an example, my father who knows next to nothing about real estate purchased a 7k sqft gated dirt land  in the city 3yrs ago for $35k cash, was planning to invest in it but it was too much hassle for him so recently he sold it for $140k .What's a good way to find good deals on empty dirt land  in the city or close by, does mls offer this search option.

Hopefully that will get them to take the cash for keys option. 

The numbers work and seems like I’ll be getting around $500 per door (cash flow) however I’m not familiar with the area and want to make sure is a good investment.
