Templating an existing deed with new names for a new deed is certainly not rocket science, but what dollar value do you place on your time?
For $150, I'm entirely willing to have LT Transfers correctly prepare a new deed, get it officially recorded, notify resort with copy of new recorded deed, provide copies of recorded new deed to buyer and seller. I would certainly never consider "skipping" a formal purchase and sale agreement, nor would I "skip" obtaining a current estoppel in the transaction process, but that's a personal choice that people are certainly free to make --- at their own risk.
I would also point out that Florida law (as revised several years ago now) provides a 10 day rescission period, even for timeshare resales. A seller failing to provide formal notification of that FL law and fact to their buyer for a FL timeshare transaction automatically (by statute) changes that 10 day rescission period into one full year instead; an egregious yet easily avoidable error of omission. I will personally choose to leave all that to the pros.
