Just note that if you buy from Disney, you can make reservations using your points as soon as your paperwork and loan (if getting one) is approved which is usually a couple days after you return the paperwork and a month before closing. The process from intial agreement to buy and down payment, to sending signing and returning papers, and then getting approved can take anywhere from 10 to 20 days depending on how fast you return things and closing generally occurs about 30 or more days later.
