I just wanted to thank everyone SO much for the advice. I really haven't felt that low in I can't remember how long. (When I thought we might be letting the house go... I just felt sick.)
Anyway, after doing a bit more research (on the comps), more soul-searching & realizing we really do have to follow our gut, (we're the ones who have to live here, right?) we made a counter offer.
We'll be waiting to hear back, but I just can't tell you all how much I appreciate all of your advice & stories & I really do consider you all my friends- thanks so much :)
have a great weekend!!
