There is actually a lot to make sure of and things do change in a case by case basis, but here are some of the General things you should ask about (IMO)
1) check with the town/city if the park is legal or legal nonconforming and if so how many spaces .
If the park is straight up illegal, you can stop your questioning here. Don’t even go forward. You can be shut down as soon as you sign the paperwork to take control. Not a risk I want to take.
2) Does it run on public or private utilities?
City water and sewer, or wells and septic tanks?
Or even lagoons and waste water treatment plants? (I would avoid these personally due to expense and other issues that can come up)
3) is the park in a floodplain?
A very good thing to know especially if the area is prone to rain.
4) how many homes are owned by the park or the residents?
The model that is preferred here is to not own the homes but instead the land under the homes only.
5) a phase 1 environmental survey.
The other steps can mostly be done by some legwork and asking the right people but this one will cost you money. I think it’s better to do your own from an unrelated third party since there are some sellers out there that are less than honest.
If the phase 1 comes back as a failure, I’d say stop your due diligence here and Mose on to another deal. Environmental cleans up can be MASSIVELY expensive.
There are many other things to check like the metro area, crime rate, average rent of the area, etc. but these are the basic things I think you should know.
There are investors here who know a ton more than I do so they can probably fill in some more details. I hope this helps you a little. Good luck!
