Actually while is isn't common, it isn't that uncommon either. In the last couple of years (since we purchased), I've seen multiple contracts listed separately and together on a couple of the websites. In all cases, it said that there was one closing fee. In most cases, the contracts were between 75 and 125 points each. You need to look very closely at the listings to see that they are being offered as 2 or more contracts. It just doesn't jump out and bite you.
So there is a way to get 2 smaller contracts in this way. Just don't be in too much of a hurry.
