If you are financially stable on your own, then they'll have no problem selling you a contract.
Currently, Disney is selling Saratoga Springs Resort (SSR), but if I am not mistaken, they also have some points at other resorts that they have gotten through ROFR, which they also sell. As I said, I may be mistaken about that, but I seem to remember reading it somewhere...perhaps here on the DIS!
In any event, I would say buy where you want to stay. Your home resort gives you an 11 month booking window, a non-home resort gives you a 7 month booking window. Depending on the time of the year you want to go, that could be an important factor. There are now 5 DVC resorts on Disney property-Old Key West(OKW), Beach Club Villas(BCV), Boardwalk Villas(BWV), Wilderness Lodge Villas(WLV or VWL), and Saratoga Springs Resort (SSR). They are all themed differently and located in different areas of WDW. BCV & BWV are in the Epcot/MGM area...you can walk/boat to both major theme parks, VWL is a boat ride from MK, SSR is a walk/boat from Downtown Disney(DD), OKW is a walk/boat to DD. OKW has the most spacious rooms, but all properties have amply sized units for a vacation condo. OKW has parking right outside your door...it is more condo-style. BCV, BWV, VWL are attached to hotels. I have stayed in OKW, BWV, and BCV and like them all for various reasons. I am not sure about SSR, as I haven't seen it yet.
As far as financing...when DH and I bought our first contract, with OKW as our home resort, in 1997, we bought directly from Disney, and took the 10 year loan. Our thought was that we could certainly pay it off sooner (and we did!), but if we had a month where money was a little "short" the 10 year loan had the cheapest monthly payment and that was all we HAD to come up with. That worked for us, as did having them withdraw the money directly from the checking account. The dues payment was included in the total, so we worked it into our monthly budget and it wasn't painful at all.
The second contract we bought (again at OKW...we like it there!), we bought through Pat Spell at The Timeshare Store. We got it just before Disney got really crazy about ROFR, so we got our contract for a good price. At that time, we were able to pay cash for the points, so it was quite quick, easy and convenient. I think from the day we made an offer on the contract until the deed was recorded was about 8 weeks, no hassles at all.
I know people who have very creatively financed their resale DVC purchases. Friends of ours put it on their "cash back" credit card and got the benefit of that, and then paid it off the next month. Another couple used their home equity line of credit so they got the tax break for it. It's hard to get a personal loan, I think, for a timeshare purchase, so financing a resale through one of the resale companies will take a little more creativity.
Good luck and keep asking questions!!!
