Terry, your description of their business is close but they don't buy the TS's, they get them for free. Most of their inventory comes from developers who take TS's in trade from new buyers. If you own a TS and are interested in buying a new one directly from a developer, the developer will try do to anything to make the sale including giving you something for your existing TS against the inflated price of the new TS. When they take TS's in trade that are not their own, they just want to get rid of them ASAP and a lot of them have a deal with Intervalmax to take all that they get off of their hands. Some of them are literally worthless (a lot are the type of TS's that post card companies charge people to take over) but some are pretty good, like the Hyatt's and Marriotts. They don't get a lot of these but do get some. From what I can tell, they get a ton of TS's from these developers. Probably on a lot of them (maybe most of them), the profit they make is the closing costs (they do the closing in house at a very low cost). It seems to be a good business model, but low margin/high volume, and they know what they're doing. I've bought 2 TS's from them (including the Marriott Timber Lodge that is still in process). I think they get estoppel letter of TS's before they advertise them for sale to be sure everything is as described. But it is scary not having a third party closing company holding your money until the TS is transferred.
