Sam Rodriguez and Seth Nock (and Sellingtimeshares.net) have been around for many years
(maybe two decades), and their reputations are stellar.
I sought Sam out for two resale purchases in the last 5+ years,
and both went very smoothly and quickly.
He also recently sold a Marriott week to friends of mine who were referred to him by me,
and they are thrilled to begin their timeshare journey.....lowest price I've seen, great service, & closing is imminent.
I knew about him long before I decided to purchase, and all those who dealt with him during that time were pleased.
He and Seth have been well-known around the TUG boards since the late 90s.
Both are honest, hard-working, and very timely in their responses.
If they don't have exactly what you're looking for, they'll find it.
Sam stays busy, so if he doesn't answer right away, try calling him.....he's always gotten back to me
within a day or two at the most. He has a family and a life too, but I know he will take care of everyone the best he can.
He's as reliable as anyone I've ever heard of in the business, very worthy of any accolades he receives,
and I recommend him without reservation. Ditto for Seth.
