Would you buy a park already at market-rents?
One suggestion, If rents are at "market" their is an opportunity to operate the park more efficiently, controlling expenses, specifically water/sewer utilities. Allowing your residents to control (and pay for) water/sewer expenses, will reduce your community's water/sewer cost by 25 to 35% (documented).
So even if you reduce (not often done) your rent by an estimated per unit utility cost and have your residents pay for their fair share of the expense (now reduced 25 to 35%) through sub-metering, your still ahead.
Sub-metering is a sure fire way of increasing your net revenue.
