Nevertheless, this routine has blessed my marriage and helped me whenever I want to pursue something major that requires time and investment.My advice above, however, only addresses the issue of not feeling prioritized.  

If needed my wife can live in the house if marriage plays a factor?

What pisses me off is that they always have people over, I've had teenage kids from previous marriages living there and then their family from abroad, then it was the husbands brother.

Marriage is a legal partnership.

A first day is no marriage.

We also don't know when you acquired the properties -- before or during your marriage, or if you acquired them with community funds, or what Washington state law says regarding out-of-state real property. 

When two people walk down the aisle, they think they are getting married until they die. 50% of the marriages end in divorce.

The other thing that I’m thinking about is house hacking, I also figure it may help with question 1 and the time, since I’ll be living right there.3) Personal Life—I’ve been with my girlfriend for over five years, and marriage is on the horizon once she finishes her graduate program (another two years or so).

Also figured I would cover that I have no interest in marriage or children as of now.I am in a unique situation where I have my tuition covered with a trust fund of sorts and will have roughly 30k remaining after I finish school.

Let’s say inthe future after a long loving marriage with lots of kids and what not, I pass away without a will or anything like that😢.
