Thank you @Frank Rolfe, @Patrick McKenna and @Hai Loc. I have a 20 lot site on radar (come with homes + lot) that is already set up and working wonderfully thanks to previous owner as well as a 60 lot site (lot only). The general lot rate in the area is between $400-500, and if the mobile home is park owned then it's around $1-1.2k a month.
I only want to deal with honest people who REALLY know what they're doing and are capable of communicating strict rules, but it's not easy to find experienced people who aren't attached to another site or way up there in years looking to retire.
Was thinking 20 lot site with owned homes - (Estimate $205k collected annual factoring vacancy) 1 lot w/ home + $1,200/month . 5% of rent roll would be $950/month, but they would also have to oversee any repairs needed to the homes themselves which would inevitably come up.
60 lot site - (Estimate $264k collected annual factoring vacancy) 1 lot + $2,000/month . 5% of rent roll would be $1,200 .month
Because these are smaller sites that are normally moms and pops managed, I feel overpaying would be the only way to get a solid manager.
