Offer on the house

Finally! We have an offer on the house we bought for $274k. The offer is for $142k. I'm feeling ambivalent about it. On the one hand, happy that there won't be anymore mad dashes to tidy up toys, laundry, dishes, etc so a Realtor can bring someone over. On the other hand, sad that we are totally losing our shirts on this stupid house because of the stupid market and the stupid economy. And part of me feels like I should feel one or the other of those more strongly but there is a certain level of indifference to the whole thing too. I don't really get attached to houses the way other people do. I don't feel the nostalgia for them that other people talk about.
The next step is to get our crappy mortgage company to accept the offer. They are crappy because although they were cheerful and helpful at first, they have managed to harass our Realtor for an offer (as if it's in his hands) while simultaneously denying they've ever heard of us. And this was the same bank employee on the very same day! She must have multiple personality disorder.... Also, she lost our paperwork twice and when Erik sent her her own email where she had confirmed receipt of the paperwork, she suddenly remembered all about us.
We have about another week and a half before we could hear from the NZ consulate about our visas - at the earliest. So, Erik's employer has asked that we schedule a date for the moving company to "pack and uplift" our household items. We've scheduled that for the Monday and Tuesday following Thanksgiving. We have to have our visas in place before Air New Zealand will let you book a one way flight so, as soon as we get those, we will book travel. But we're tentatively thinking we'll be flying out of LAX on December 2nd.
On a happier note, since the whole process has managed to take so long, I've booked a flight to Denver to visit my parents (without the kids) for a few days next week. And Ben will be starting preschool here in Phoenix three days a week until we leave. First we were waiting for him to get potty trained but then that happened, and then we thought we'd be leaving soon, but that got delayed so we're just going to go for it. He's so excited to go to "school". He starts Monday but has already been for a familiarization visit.
