Centralized mental health is a necessity. 

Due to my time limitations, I went with LO mentally.

That department is runned by dinosours who are set in their 1950's mentality and will make your life hell. 

They can gaslight you, but that is just a distraction.They actually sell wipes to detect pot residue on walls, but I am not sure if they work and I would not spend the time or energy in engaging in establishing "proof" - you'll put up walls and they'll just dig more tunnels.Instead, I would:Contact their case worker ASAP, cite the behavior as a lease violation with her, and state that in addition to it being a breach of lease, it is creating health concerns for your family. 

Throw in that many first time home buyers are also the ones who could get hit the hardest with the potential increases in health insurance, rising taxes and property insurance. 

Especially the first time something bad happens (and something bad will happen) such as an eviction, slap leak, collapsed sewer run, new roof, etc it could be challenging to see the positive of having a cash negative rental.Make sure you are mentally prepared to supplement this property for potentially years through some difficult events.good luck

I have been researching and studying for about 5 years but after the global health conflict personal tragedy struck with the unexpected tragic loss of my child having to set things aside.

Concerns such as the home value decreasing, 24/7 humming noise, increase water bills, increase electric bills and other environmental concerns in regards to health. 

To file the paperwork doesn't cost THAT much, maybe a couple hundred, but the nightmare of getting someone out could take a mental toll on you and ultimately end up costing you thousands more - especially if they trash the unit. 

So, if a guy wanted to, he could take a zip code's average income, and the same zip code's average house price and determine the "health " of a zip code, or find buying opportunities.
