If you want BCV, you really do not have much choice. As you've already noticed, there are not a lot of resales on the market for BCV. It's too new.
IMHO, since you will be getting 02 points, an appropriate use year, and not paying closing costs, there really isn't a lot of advantage (and maybe not any at all, LOL) to going resale anyway. From other reports, it sounds like Disney is buying back most of the "good deal" resale contracts right now, anyway. And again, you want BCV. How long do you want to wait for the "right" BCV resale to appear??
Good luck - hope to welcome you home very soon!
