In fact on the beach here in Boca Raton - $850 is on the low side -
Most exceed $1000 -
I am sure you can get the disclosure docs indicating exactly where the money goes and what privileges are included.
In Boca Raton we have many Country Clubs that require $50,000 + to join and then over $1000 per month in "social membership" dues... + hoa... + golf , food and beverage ... + + +
Come it's a lifestyle of your dreams!
If you need to finance this purchase you'll have to find a lender willing and my guess is, interest rates me be a little higher.
Hope this helps.
