I can tell you AS A FACT, that if you change your ownership to an LLC and YOU as a developer purchase stay as an authorized user, you WILL retain VIP status and it will never leave. That is a fact and anyone who wants to debate it can PM me and I will send the screenshots. The same is true for a trust. These are not loopholes. They cost more money but they are legal rights of ownership which cannot be denied by Wyndham. An LLC is just as much an entity as person, again this is not debatable. I have it so let's find something else to argue about. You are welcome to call title services and ask them about placing ownership in a trust or LLC or other entity and how one would go about adding authorized users/owners (hint: they are the same and known as other owners up to 6).
Now does this transfer your recently purchased resale points from a person who was a developer purchase to you with VIP status included? No, but there are other loopholes. In the past there were opportunities during the recession to trade in resale points and purchase more points which would convert everything to developer purchase (this was offered to me). There was also the 'friend' of a salesperson in title service would press the right key when entering a contract. I cannot comment on these beyond them being told or shared with me but I'm sure it happened. There is also the random mistake. I had one of those happen to me. Bought a resale contract and it showed up in my account with developer VIP. Don't know why and I didn't call to ask.
There were several legitimate, known by wyndham loopholes back in the day, like Ron said some if not all have been closed. I am not an expert on all those various options but remember this - you can have up to six people on the account/ownership and VIP status is extended to all of those people. Several years ago it was posted on here that one could purchase a VIP membership by adding the buyers name to the contract and leaving the other's name intact, which moving payment responsibility to the new buyer. That got me thinking and I developed a way to transfer a vip ownership to one of my accounts. The question is this - is it hit or miss when you remove the original owner? I don't know but I know I had numerous conversations wiht title services back when I first learned of it and it was allowed but we decided to go another route for long term ownership.
Example: You buy 1m points VIP. Leave seller on contract. Add yourself and wife. Change payment responsibility to buyer, place credit card on file for automatic payment. Everyone has VIP. At one time (cannot confirm today) the seller could later be removed and VIP status remains. Again, this is not debatable with me as I can claim this being done by a business partner, but I cannot confirm it is still possible today.
The point here is that there are ways but they are not obvious and they are only known by a few who have done it or paid the money to have it done. If everyone started doing it, they would go away and most likely they have but once granted they are not going away. One thing I did learn. Wyndham has no historical information when they transfer a deed or contract. Just try calling them and asking them who owned your contract before you. They have no idea.
