how are you feeling about it, Steph? i know laws differ from state to state. in my state, the closing would never happen that quickly, but when we sold my mom's house in NC, it only took a month to close, because both parties wanted it that way.
if you're feeling, anxious, try not to future trip till you know it's been sold. (said the recovering future tripper)
and by any and all means, pray and remind yourself of all the times God was faithful and took care of you. best cure for anxiety i know, if you're anxious.
moving is hard, and i am praying.
