Here's the problem with financing, especially if you're buying direct from Disney.
There's only one reason to buy DVC, and that's to save money on the villas. If you buy direct through Disney and finance at their insanely high rates, over the life of the contract, you're not saving money. If you're going to finance for the full amount of time they'll let you (I think it's 10 years), you could potentially be paying double or triple what a resale buyer who doesn't finance will pay.
If you can't buy without financing, there's just no advantage for you in buying. I'd recommend renting points instead. You get to stay in the same villas, at the same resorts, and have the same experience, without the long-term financial commitment, without the huge interest charges, without worrying about your credit score.
The other advantage to renting instead of buying is that you only pay if you're actually going to take a trip. If you buy, you're paying that loan and those maintenance fees every single year, whether you're using your points or not.
Remember, only your resort costs are covered by DVC. In order to use your points on, say, a trip to WDW, you're still paying for airfare or gas, park tickets, food. If times are tight and a trip like that just isn't in the cards for a year or two, you're still paying for DVC.
