Pay more up front for the yearly amount 15 %,then you should  see no nickle and dimes when working on the rentals for all the stuff that goes wrong .Unless you bought a house that needs tons of work .

Recently I feel like the PMC is nickel and diming our tenants.

If you can't make a profit because of a PM nickel and diming you, then just sell it. 

Most of the people who have trouble here are the people that try to nickel and dime the pm too much or have unrealistic expectations.

Newbies are notorious for this and they wind up stepping over dollars for dimes.

If I were in your shoes, I definitely wouldn't want to come up with the dime for paying on something like this.

The side-by-sides are a dime a dozen but the stackable makes seem to be a bit harder to come by.

Offer them a simple form for a payment plan if the charges are too much.It's very likely they will ignore you and you'll never see a dime beyond the security deposit.

They are a dime a dozen, just find one that fits your needs. 

Even if you don't see a dime of remuneration (because you decide it's not a worthy pursuit or because it doesn't go your way), you will have learned many times the $6k worth of lessons if you get down to the root causes and build your processes to prevent that happening again.Be well,
