The residents above are chronically violating their lease and a true nuisance to live below.

We don't do them very often but when we do it is usually due to chronic late payments, not caring for the property per the lease, owner selling, tenant is difficult to deal with, etc. 

We have had good results with changing them out and some chronically leaky faucets.

I'm noticing too that people are largely ignoring Covid precautions, which could partly explain the chronic problem with cases here. 

@Joe P.I grew up chronically poor.

Here's a link to a recent growth development article in case insomnia grabs ya sometime....https://www.wenatcheeworld.com/news/2016/nov/30/sewer-line-opens-area-near-east-wenatchee-to-more-development/ 

Here I thought I had insomnia!

Keep in mind, eviction screenings do not protect you or your client from those tenants who skipped out in the middle of the night, did a cash for keys or who were chronic late payers and court records won't show an eviction record right away.

Now that my overactive mind has had a chance to relax after getting all of that ^^ out after a couple of intense days of twisting and turning ideas and insomnia, I'm realizing that while the whole TIC + 121 + 1031 exercise was helpful in that it brought us to a spot where we came up with the idea for how to take the $500k cap gains exclusion from the sale of just the upper, I see now that the whole 1031 motivation that inspired all of this thinking isn't actually necessary/beneficial.

The previous owner never enforced the late fees, although one of the tenants was chronically late (undisclosed at time of sale),I sent all the tenants a change of ownership letter restating the terms of their lease, including the late rent penalties.
