Question:
What is leased or certificate property?

Answer:
This simply means that you have the right to use your timeshare for a specified number of years, after which the ownership reverts back to the developer. Certain resorts may allow for accelerated usage which means that you will have a specific number of weeks you may use, but you may use more than one week per year. Most properties in Mexico and several other countries are of this type as the government tries to prevent long-term foreign ownership in their vacation cities.
