I am so sorry about the house, but you did the right thing in not purchasing it. The right one will come along in 2020 and it will be the perfect fit for all of you.

Keep an eye on your D's college fund. She may not sign it again this week. This may be her only avenue for communication w/you and I do not think she forgot about signing and removing her name the last time around. I may be wrong, but I don't think so.
Wishing you and your family a very Merry Christmas! May the new year bring a life full of pleasant surprises and a new home for all of you.
