Unlike child support, spousal support is often very difficult (if not impossible) to modify after the divorce is final, so getting it right the first time is a must!
Capital gains on house can be considred income..In some states it needs to be over 250,000 however if the money gets rolled over into another property it would be just an protected from any taxes. Same as taking money from a 401k it would be income until you roll it back in to a retirement plan. I'm just having a Pam theory but when you make a lot on your house it's taxed as income.
