Last I heard, BCV was $115/point if you buy directly from Disney. IIRC, there are no current incentives available to reduce the price for BCV.
The minimum contract size for new members is 160 points and for existing members seeking to add on, the minimum size contract is 25 points. Not sure all use years are currently available. You may have to make a deposit and get on a waitlist.
Many times you can get this info from DVCNews.com. DH and I bought direct from Disney in June 2009. We purchased 210 points at AKV and financed. If you have any questions about that process I will be happy to help you. Just ask.
