Gekko, sounds like you are handling things well, it's expected that you're feeling a little down, that's part of it!
Regarding the home and your thoughts that W will lowball you, I kept our house and as part of the D had to get an appraisal done. I think it cost around 250 bucks. An independent appraiser will review your house inside and out and note any deficiencies in a report. They will then review comps in the neighborhood and prepare an official report with pics of the house, pics of the comps, condition description, etc. And that report will assign a dollar value to the house. That appraisal became part of the D decree and settlement described in the D. At that point there's really nothing left to argue!
