Also keep in mind these houses range from 80-130k. 

Things like moving homes into the park to fill up vacant spaces, renovating vacant park owned homes (which is radically different than the renovation of site built construction), selling homes (along with licensing requirements), carrying paper in the correct fashion, crafting the correct leases and notices with respect to the landlord tenant regulations for MHPs, etc.  

I've found it a grea market for finding quality rentals, right in your price and rent range. 

Whatever it is, you have to respect the blood, sweat and tears (literally, sometimes) that it takes for someone else to finally become a 'successful' investor.

@Colleen F.has posted some items to consider with respect to consideration for the occupants. 

Theres a about 10-15 that I'd consider in the 15k-70k asking price range.

What is your price range??????????

That is the price range I shoot for. 

Plus i caught a guy taking my sign down (another wholesaler) waste of money.While i wait for my yellow letters to reach their respected audience I have been focusing on probate letters and learning lease-too options.  

The parents/students are still on the hook for the 15K-20K in room/board/etc, so some of those families in the 70 to 90K range probably are having to borrow for that.
