Not all timeshare is the same but the basic concept is that you buy 'time' at a specific property and you only pay for that time. You can purchase as little as 1 week a year. Besides the purchase price, you are required to pay an annual maintenance fee that covers the costs of managing the property, taxes, amenities, insurance etc, etc. The fee increases every year and is completely out of your control. Many timeshare properties offer you the ability to 'trade' your week with properties around the worId. This seems great but there are additional 'exchange fees' you have to pay and it is VERY difficult to get the week and the property that you want. Plus, you have to pay your airfare, food etc. Financially, it makes no sense. You can get much better travel deals from an agent or online and go anywhere, anytime you want. Also, if you ever want to sell it...forget it! You can't give away a timeshare resaIe. I sold high end timeshare (we called it 'Fractional Ownership') for years and I had to quit because I knew what a bad investment it was. I would NEVER recommend timeshare to anyone.
