So far, we have not had to do this and we are hoping not to have to do it very often
Because of the way we bought and the extra points we got for when we added on, we have had extra points to bank the past few years.
By 2012, however, those extra points will have run out so we will have to stay within our 210 point limit or start borrowing.
Of course, by then, I am hoping to convince DH to add on more points. Even with the rumors about resale points being restricted, if the price goes down far enough, I think he would let me add on at either BCV or BWV in a few years.
