@Chad Bellanger First I would call the zoning department and see if the land is zoned to be a mobile home park. If it is then I would take about 40% (maybe less in this case) for expenses off the income to get to your NOI. Expenses such as grass cutting, road repair, maintenance, etc.
I would watch raising rents that much out of the gate. Check to see what the competition is charging in a 5 mile radius from this park. Also, is there a Walmart within 5 miles of this park? if not, it may not be a good choice. Your customers shop at Walmart.
When you say "renters" do you mean that the mobile home is owned by the person living in the home? OR are they truly renting the mobile home from the park owner? Typically if they own the home they are called Tenant owned homes (TOHs) and the ones that are rented are called Park Owned homes (POHs).
Another FYI for you - if these mobile homes are Park Owned (rentals) the banks and appraisers don't take in account the income from the rentals - they in turn assign a value to the mobile home itself based on it's age, e.i. 1970's mobile home maybe only worth $5,500 and they use that $5,500 only not the rental income that the unit creates. So the older the home, the less it is worth - if Park Owned.
If you want to PM me for follow up please do. There is a little more to Mobile Home Parks than most think.
Glad to help
