Timeshare sales. Are they out of their minds $30,000 and $2000 a year maintenance. Buy it on eBay for a dollar if you want one. I would still be leery of the maintenance fees. Who controls the raising price. Would you live in a house or condo with $36,000 a year an maintenance fees? Then why would you buy one that charged a $1000 a week? Who controls the maintenance fees. What happens if they double?
