I have posted this information several times in the past few years, but I have saved it so that when it keeps coming up, I can find it.
Before August 2002, transfer fees for Mayan Palace units were the cost of Maintenance fees for 1 year. The Vacation Fair week transfers with the contract. (A large majority of these have now upgraded to Grand Mayan and their old units are sold with the new terms.) Contracts were renewed every 25 years for up to 100 years (5 MF each time) and there was a 5 year Renovation Fee that was equal to a Maintenance Fee.
From August 2002 - November 2005, it was 10% of the original purchase price. The Vacation Fair week does transfer with the contract. I am not sure they started selling Grand Mayan units before 2003. This was the information for Mayan Palace that was in a contract that we had. This also has the 25 year renewals (5 MF) and 5 year Renovation Fee of 1 MF.
The 5 times the MF to transfer (sell) to another person started in late 2005, just before we upgraded to two GM 2-bedroom units in April 2006. These also had a 5 year renovation fee that is equal to 1 MF. The no pay unless you go feature was new in 2006, but came with an addendum that if you transferred your contract to someone else, the Vacation Fair (bonus week) and the no pay unless you go feature does not go with the transfer. This also had the 25 year renewal fee of 5 MF.
In 2008, there were some contracts that still had the 5 year renovation fee that was then 1-1/2 the cost of your MF, and still had the 5 times the MF to transfer to someone else. These also had the 25 year renewals.
I am not exactly sure when, but by the time we upgraded to the Grand Luxxe in 2013, the cost to transfer your week to someone else had gone up to 10 times the MF and none of the special benefits, especially the no pay unless you go and extra weeks go with the transfer. The new contracts have some 10 year renewal options which seem to change regularly.
