Does anyone have advice as to how far away to stay from specific addresses that signify past permits to fix sinkhole, or potential ground settlement, issues.

I've seen the absolute worse case marital problems (use your imagination) get turned around.

An unlimited marital deduction allows for unlimited tax-free transfer between spouses during life provided that both spoused are US citizens. 

Account Closed - WA is a community state - items considered marital property are generally split equally. 

You could also sell it and get all the proceeds [$250k to $500k depending on marital status] tax free assuming its your principal residence.

Plus the slight delay is going to be WAYYYY worth it in terms of marital harmony, which is, in the end, the most important thing.

This answer is specific to your personal situation (income, marital status, withholding, and many many other variables.) 

Here is the guideline for establishing a domicile:To establish domicile, you or your parent(s)/guardian(s) must meet the following criteria: Live in Texas for 12 consecutive months; andEstablish and maintain domicile for 12 consecutive months by doing one of the following: Be gainfully employed in Texas (student jobs do not qualify as gainful employment);Have sole or joint marital ownership of residential real property in Texas by the person seeking to enroll or the dependent's parent, having established and maintained a domicile at the residence;Own and operate a business in Texas;Be married for one year to a person who has established domicile in Texas.

If it's all in joint accounts, marital units are good to go no matter what.However if each spouses is getting mortgages individually, and the funds are not in joint accounts, you can get jammed up.

I also think this means that you both might approach money and finances really differently which is often a cause for marital issues (it’s exacerbated once you have kids actually).
