With the 50/50 custody, I worry most on how your daughters are going to adjust with living in 2 homes. Does your W have a place where they can have their own rooms?
Get a parenting plan done first and then deal with the financials. I hope your STBXW has the best interest of the kids in her mind and is not wanting 50/50 for child support reasons.
In my case, the 50/50 parenting plan went together very well, and then the financials was a back and forth with the lawyers. I came out ok since we agreed to a buy-out of the spousal support which I was able to pay (including division of assets) with a refinance of my house.
