I think the numbers are all off. You don't happen to have the contract in front of you. I own at a Coral Resort and went to one presentation several years ago and keep up with the typical pissed consumer/ripoff reports.
My guess would be minimum buy in would be $13000. They may be telling you a ten year finance rate of $1395 per year not including finance charges. They may or may not take your DRI, and just say they are taking it in to reduce the price and they may be dumping it on a company that bulk buys (takes for a fee) trade ins from developers or you may find out they were just going to market it but you still end up owning your original deed and still owe all the MF's on the old week as well.
What you are buying, based on the MF, is an eoy 3 br unit. If you are lucky it would be a platinum in their newest section that gets around 124,000 per year so you will get around 62,000 per year on the EOY week. Knowing them more likely for the $13000, you are being sold an every other year silver or bronze week that for the same $1000 MF per 2 years only gets you 62,000 points every other year. They also throw in an every year developer week but you have to pay the full $1000ish MF and it can only be booked 60 or 90 days in advance so no prime weeks would be available as developer weeks.
Any which way you cut it, you will not be getting a good deal.
Coral resorts also makes it difficult when you go to sell. They require a $1500 transfer fee of which $500 goes in their pocket and the other $1000 goes toward future MF;s for the new owner. So even the best weeks which at one point had a value of $1-$500 per week now have a neg $1500 to neg$1000 to get it in the hands of a new owner. Weeks that cost more than a penny per RCI point cost even more out of pocket to find a new owner if one can be found at all.
