The only grandview units that have any value are those in points that get 122,000 or 98,000 rci point,s for a 2 br or 61,000 or 49,000 for a 1 br. Even then the 2 br for 122,000 points at the high end sells for about $3500-4500. A 49,000 1 br may sell for about $500.
Everything else is in the giveaway territory and may take a fair amount of effort to even give it away.
