Make sure you know exactly what you are getting. Advanced Financial is the company that handles all Grand Pacific Resorts and they make mistakes and also change their "rules" whenever they feel like it.
What is the season/week/size of the unit? I own a one bed and a two bed there. Neither are 5000 points. Both are what HGVC considers to be gold season. The resort allows booking weeks 1 - 26 and 34 - 52, I think. Some of those are platinum in HGVC, but the points always stay the same. 2 bedroom is 5800 points, one bedroom is 3400 points.
GPR charges $995. to transfer HGVC ownerships. If the unit is removed from HGVC, they charge $695 to remove from HGVC and put back to normal resort week. If it is not already HGVC, the transfer fee is $450. <- That's all based on what they told my broker when she sold one of my weeks last year.
The MFs you posted sound about right for a one bedroom. It may be a little higher, but not much. Two bedrooms are more like $1100.
