Wholesaling mobile home park

[Matt McConkey]

My business partner and I have come upon a mobile home park near Houston and they're looking to sell. I have a list of question below, but was hoping there might be some more I might need to ask to ensure this is a good deal/everyone involved can win. 

does each unit have it's own water meter?
how do tenants pay?
what is the gross income per month?
what are the operating expenses?
average occupancy rates? how many people who their own mobile home?
what do they pay?
how old are the mobile homes?
