There is a tremendous amount of bad information being spread here, so be careful who you're taking advice from.  1. 

I own thirteen mobiles in one of my parks and the only way it pencils is that we A) take very good care of the homes staying ahead on the maintenance, B) Rents are high in the area so we can charge $550 over the pad rent which is $450- so $1000 per month.  

It’s not uncommon to rent by the room to individuals, but it requires some careful management.

Do they care if it's financed or cash? 

I have cleaning services, handymen, plumbers and kind of an electrician I call should the properties need something.

I would be careful about doing something in an effort to "make positive cash flow".Section 8 has its pros but there are an equal number of drawbacks.

Finally, we do not care about your tax returns, etc.- since these loans are primarily based off of the asset as collateral.

HOWEVER, I recommend reading Stuart's advice above very carefully and perhaps soliciting his feedback on the deal in more detail before putting too much more time into it. 

That has led them to continue to jack up rent prices and often, push out good tenants for the sake of an extra $100/month.

I think it’s the only way to go, learn a lot, you care for your property the best you can, etc.Steven
