I would call
DVC and speak with one of their sales people. I never thought I could afford DVC...NEVER. But when I thought of all the money we spend paying for a room on property, and we go 4 weeks a year, it only made sense to go with the DVC as a pre-paid vacation. My sales rep was low key, took his time to explain everything to me - no high pressure. I called back and bought a 150 contract, gave 5% on my credit card, they mailed me the contracts to sign, I signed and sent in the other 5% required for Disney financing, and have everything direct debited from my checking account. I then added on 3 times since. It was interesting that nothing shows up on your credit report about Disney financing.
I financed 500 points with the 10% down. I have contracts at SSR and VWL.
I pay $501 a month in loan payments and $159 in annual dues per month.
So that may give you a ball park estimate.
Yes, I know many people will say that if you have to finance it, you shouldn't. Well, I disagree. I can afford it and it pre-pays my vacation. I just make my reservations and show up. Nothing to worry about. Also the $100 discount on Annual Passes is a great perk.
Go ahead and call. Get the information and look it over and then decide.
Best wishes
