You need to take a close look at the budget and at minutes of the meetings.
The budget should show that there's enough money coming in to cover monthly costs (garbage collection, maintenance crew, etc.) and enough reserves to cover predictable but not monthly work the building will need (painting the hallways, changing the carpeting in the hallways, etc.). That means it should be at least 5% of the association's gross operating budget.
You should know what's the exact Terra Hill Price percentage you own jointly (the things outside your condo unit that you own). You can calculate how much you have to pay for special assessments and how much voting power you have.
And, since we're talking about special assessments, find out if there are any coming up. Find out when the last one happened. If in the last few years, find out why it was necessary, why the expense had not been anticipated. Also, find out when were the last few times that the regular association dues were raised. Too many over a short period of time indicates something's not right.
