Which knocks $42k off your estimated annual profits & brings them down to a piddly $14k/yr.

@David M.The better managed funds will have audited financial statements and typically also submit semi annual or quarterly reports.Those that go regulation a+ also have to submit to the sec so their information is all public.Like anything, some private are better than public and vice versa, really comes down to the sponsor/CEO and the team in the majority of instances.

I've been thinking of adding an annual 2% cost of living increase to new leases.

Review all of this and then see if it matches your appetite.For example I have seen someone offering 40% annual returns.

Our combined annual income is $150k, with somewhat limited potential for salary growth.

Especially when it comes to annual property taxes and annual landlord insurance policies. 

You can always ask for a tax recert and challenge the assessment file a petition to the VAB value adjustment board and dispute assessment.If all of that fails start looking at investment properties in states like TN, LA, AL, GA, FL, these states in the South East can offer super low annual property taxes. 

They are quickly becoming known for their high and annually increasing property taxes.

In diligence, compare the prior annual revenue to the reality of electrical usage (come up with a constant of power cost per day per occupied space and then take the actual power bill and see roughly how many occupied units you have).Much of RV park and mobile home park is 100% overlap: how to find them, negotiate them, do diligence on them, renegotiate them, finance them, turn them around and operate them.
