OK, I'm doing this all from memory so some of it may be a bit 'iffy'. We bought into
DVC back in 2007 using UK financing (can't remember the name of the company they use but I'm sure someone else will know). We bought 200 points at around $115 per point but at the time they were offering a discount per point, which we used to offset the payment (so basically that covered our deposit). We financed the remaining amount (around $21000) and were paying approximately £110 per month. We paid it off in full back in October 2008, which is why I'm a little sketchy on the details.
There are a couple of points I do remember though:
DVC US financing do not run a credit check, however the UK financing does.
You can use any discount offered as a down payment/deposit however DVC financing, I believe, requires a greater deposit than UK financing.
For some reason, we thought our payments would be a fixed monthly amount but the amount we paid per month went up at least once in the short time before we settled the account (due to change in interest rates perhaps)
If you have any further questions, please ask and I'm sure people will do their best to answer. I am at work right now so don't have exact figures here but would be happy to share them via PM if you are interested.
