Expressing an opinion is not grounds for eviction as freedom of speech is protected in the Bill of Rights.The tenant was clearly hoping to upset your sale, and may continue to do so.   

Let me know when you're scheduled to give your next motivational speech.

There is almost no amount of money that I would trade for my time in college and the 25 years of friendships afterwards with my college friends.And I did learn a lot too...language, math, reading, writing, speech, economics, marketing, accounting, psychology, business law, communication, etc...education that I use every day and continue to build on.There are plenty of affordable colleges where you can learn this stuff efficiently. 

If you are able to run your hand between the top of the wall's frame and the truss (if it is this style) then it is not load bearing.

We do not tell them that it's okay to knock on our door, and the speech is, "If it's an emergency, call 911,"  same as when we weren't live-in LLs.  

If you need more headroom or the illusion of it and are good with a little more work, I would tear out the fails ceiling and use a paint sprayer to paint the floor trusses, ducts, plumbing, and wiring dark gray or white which is what I did in my personal home which only has 7’ ceilings in the basement.

I am too tired to give my speech about investing in Portland tonight.

Users are terrified to share their experiences when companies threaten to sue them for exercising their free speech. 

She gave me the "move in silence speech" I agreed to disagree

I will work on my speech and practice a little more before going further.
