The upside is you know what your monthly costs are they now are fixed. This is great for budgeting.
The downside is you may be you are subsidizing heat and utilities for people that may not be responsible. I've seen building where heat is included and people leave windows with their heat on because they don't care. It is especially common for a less than great attitude when there are renters occupying.
Compare condo fees for similar complexes with out the utilities included to see if it makes sense.
The fee may seem large when compared to other complexes, but if you add up all the utility bills that you would be paying somewhere else, you'll probably find that you're in the same ballpark. Your neighbors will be just as motivated to keep the fees from "skyrocketing in the future"
