Quote from @Collin Hays: I don't manage short-term any more, but can't you include this in a written rental agreement that the guest signs at the time of booking?

Including guys like @John Underwood and @Michael Baum

There are a number of Cleveland neighborhoods that would fit your criteria including North Collinwood, sections of Clark-Fulton, and Lee-Harvard just to name a few. 

Apply the 70% rule to determine your maximum allowable offer, then negotiate and get the property under contract, ensuring your agreement includes inspection and financing contingencies.Arrange professional inspections to uncover any unforeseen issues, using these findings to negotiate concessions or confirm your repair budget.

This includes interest rates, repayment schedules, and loan duration.

Lot rent is $365 and includes water.

Sorry for the long post but wanted to include all details possible.

Common fees will include a set-up fee, a leasing fee for each turnover or a lease renewal fee, marking up maintenance, retaining late fees, and more.

Again, not unless its actually that your gross income (including cleaning fees) is 100k a year and your gross rents are actually only 75k. 

Do you have someone that manages it all including bookings and customer service or just specific parts like cleaning only?
