The good news is that overtime all of the repairs become "noise" because there's always something breaking. 

You have to see through the noise and be able to pick out the one that isn't like the rest.... 

My thinking, the tree is on your site, he can't compel you to tear it down, and sounds like SEA is hard to get tree demolition permits anyways (maybe you say "yes" to developer, city says "no").Also, make sure if you do agree to it being taken down, and he pays you for it (he absolutely should pay, more than the 2k mentioned above), that there is a written agreement, that he takes the stump out, or at least grinds it down, backfills and compacts correctly the stump hole, cleans up the area real nice, and re-landscapes that area plus more on your property. 

There are great groups out there--not just great syndicators, but great operators...but they get drowned out by all of the noise. 

All in all....GRIND!!!

If the noise is during quiet hours I will issue a lease violation.

If you have a noise complaint from a neighbor, you're fined $3000.

Time to break the cycle of the daily grind and move to higher ground.

I also work hard (I work too hard at my job, lol), so Im not a stranger to the grind or sweat equity/getting dirty.I will PM you as well to get your thoughts, thanks again!

Then simply ask about the neighborhood, neighbors, noise, comfort, etc.
