This is an extremely difficult question to answer. Costs for timeshare vary immensely based on the following criteria: where the timeshare is located, whether the timeshare is deeded in perpetuity or only for a pre-determined number of years, what the rating of the resort is, what amenities the resort possesses, whether the resort is part of a well-known "status" group of resorts such as Marriott, Disney, Four Seasons, etc., what "season" is the week or weeks in question, and most importantly, what can the resort get away with.

You should know that the average cost for a timeshare in 2008 (the last year that statistics are available for) was just over $20,000.

Prices on the resale market are usually substantially lower than that, however, there are more questions you need to ask when purchasing on the resale market.
