Isn't HHI in the midst of an assessment now?
I seem to remember something about a big bump in dues which was the result of a loan secured to complete unforseen repairs. IIRC, the cost is being spread out over an extended period (10 years?) and members will be incrementally paying the principle plus interest on the loan required to secure funding.
That may not meet the textbook definition of a special assessment, but it's still a big chunk of change that wasn't budgeted into the capital reserves calculations.
