He had dropped out of college and bought up every spare inch of space and converted it into fully furnished apartments that he rented to kids for ungodly amounts of money that their parents happily shelled out every month.

Really the park is too small for you and what you are trying to do with it, and with the number of POH, your plan to convert tenants to home owners, you can not really afford to pay anyone decent ( and you will need someone decent it sounds like) to help you at the property. 

I have used hard money lenders for auction properties and then converted to mortgage. 

If we convert the units, we will get better rent, increase the NOI on the property and thus the value of the property.

Assumption from the photos it looks like it was a very professional job of converting to a multi family.

There is a smaller home (~600 sqft) that sold at the same price only a few weeks ago, but it's flipped and has an unfinished garage that could be converted into a 3br rental. 

After purchase will convert hard lender to private lender with lower interest rate for traditional loan.

Something along the lines of a year lease converting to a month by month lease in the event of rent over due for 10 days or longer.

I also converted the unit so they are now paying for their own heat.

Also, since you mentioned it was large, maybe it can be converted to a 2 bedroom for additional profit?
