You should start by ready the "Sticky" note at the top of the forum entitled:
"
Sticky - How to Sell Your Timeshare"
A Summary:
First, you need a Contract for Sale. It must have essential terms
... like sales price, escrow, who pays which fees and year of first use...
Your transfer agent needs a copy of the contract and your deed.
HGVC has a right of first refusal (ROFR)-- unless you own at Flamingo.
Your transfer agent will need a Waiver from HGVC. HGVC has forms for this.
Your buyer may ask for an Estoppel. HGVC can provide this... for a fee.
Your transfer agent takes the Deed, records it, and initiates HGVC transfer.
