This'll be real general; the good folks at DVC (your salesperson/guide can provide specifics, and they do vary.)
You'll need a minimum of 10% down. The balance can be financed over 1 - 10 years (something like for 1 year, 5 years, 7 years, etc.) Interest rates vary, from 9.5% to 10.75 or so. On a 150 point contract from SSR at $95/point, your minimum down payment would be $1,425.
The interest rate varies with the amount put down, the time financed, and whether you elect to have your checking account automatically drafted. If your credit is less than stellar, you may have to put more down.
Perhaps someone who has financed recently can give you specific numbers for their situation. I will say that financing is easy - almost too easy - to get.
