Do we still get to write this off? 

Those can be workable terms, considering as of this writing a conventional SFR 30 year rate is in the low 7%'s..high 6%'s. 

Write a polite but firm notice reminding them of the "quiet enjoyment" clause in their lease and specifying that indoor scooter riding is not acceptable.

Based on your eloquent writing and good use of grammar you seem like a smart person.

You can write off some of the taxes with the new property.

I could write an article just on this topic alone, and I will.

If I could, I'd first write that I don't have a disagreement with anything you wrote.

Expect to be asked to write a letter attesting to the fact that you value a short commute over the extra bedroom, maybe WFH is over and you have to start going to the office again, the 4th bedroom was your home office, but you no longer need it... that certainly makes sense and would also go through with any lender that ever wanted to get my brokered business again. 

Hi Dave, Thanks for writing.

I write down on them what year they were installed so it is easy to determine if we are close to the end of the 10 years.
