Tom , In reading what you have written here, I understand it to read that the 2020 maintenance fee is $1710 including the extra assessment. This is probably only for 2020 or it would be stated otherwise. I do not think that would be out of line for a total reno of the units as your regular maintenance fees would not be enough to cover that. Insurance premiums since Irma have really increased probably taking a large percentage of the regular maintenance fees and then there were repairs to make to the resort after the hurricane as well. A letter to the resort should get the answer you require.
