One woman I know can't buy a house because her DTI still includes the marital house where she still is on the mortgage, but not on the deed.  

Most to take advantage of the unlimited marital deduction clause of the revenue code to delay payment of the inheritance tax as long as possible.

The only thing I would add to that is that if for some reason the house in question was purchased as a 1031 exchange and then converted into a primary residence, the Section 121 rules are still that you reside in the house 2 out of 5 years but the caveat is that under this one limited fact based circumstance, where the primary residence was purchased as a 1031 originally and then converted into a primary residence, is that the 2 years that you have to reside in the marital home must be 2 consecutive years and also must be the 2 years immediately preceding the sale of the home. 

In Wisconsin: race, color, national origin, religion, sex (including pregnancy, childbirth, and related medical conditions), disability: physical or mental, age (40 and older), genetic information, marital status, sexual orientation (includes having a history of or being identified with a preference), arrest or conviction record, military service, off-duty use of lawful product. --- Milwaukee also adds on top of that: source of Income.)

Something along the lines of, that if you do pay off her debt and the marriage lasts less than ten years she either repays you or pays you ten percent of her income from her job, whatever that ends up being for ten years after you break up or she can get a loan and repay you what you paid off or you get the value of what you paid off in assets before marital assets are split. 

I do not charge my husband rent.Thanks,WifeNameI once had someone follow up the "do not charge rent" statement with something about "private marital services rendered in lieu of rent," and underwriting did not find it amusing.

The law does however give spouses certain rights to a property when married and one of the consequences of those rights is that a non-borrowing spouse must sign documents that essentially give permission to refiance or sell a marital real property. 

Are there health or marital issues in the family?

This seems to be a classic marital problem.

An angry husband going through a divorce that is ready to sell the marital home right NOW so he can move back to Nebraska and grow lima beans.
