Yeah, I'm really not any smarter than anyone else.
I think people are mostly just saying to be careful. Sure, you may be able to afford a house on your salary, but remember a few things.
1) If you do D, you will have to be able to buy out her equity in the house after splitting the marital funds.So if you buy a 300K house and put 20% down, youd have to give her another 30K out of your pocket to keep it (regardless of whose name is on the deed).
2) In addition to that lump sum payment, you will likely have child and spousal support. For what it's worth, I split custody of 2 kids 50-50, but I make about 2-3x my XW's salary. In my state, that meant I am paying over $1K/month. Depending on the variance in your earnings, you could be up in that range.
Im absolutely not a lawyer and the rules could be different in your state. All I think we're saying is that it is a really big decision even if you would want the house later. I didnt realize my marriage was in such trouble when I bought a new house, but sure enough, my ex left within 6 months of moving in. I guess she was hoping a new house would initiate change, but alas, it didnt.
