If you fail to follow the rules, you may open your personal assets to a lawsuit.

I just want to see if there is a way I could get her out of there, before pissing off the other 3 tenants, but also something that is legal and would not open me up to a lawsuit type of situation. 

Have you had to navigate a lawsuit, HUD complaints, messy evictions, etc?

If you fail to follow the rules, you may open your personal assets to a lawsuit.

Then after that split is taken out, we pay income taxes to Uncle Sam, errors and omissions insurance (in case there's a lawsuit), Realtor's Association dues, MLS fees (so you can look at properties on Zillow), monthly technology/desk fees to our broker, health insurance, car insurance, gas, maintenance, clothing, computer, cell phone, software, marketing, etc.

Also, note that an eviction is just a civil lawsuit seeking possession of the property and usually also money.https://www.cumberlandcountypa.gov/FAQ.aspx?

A bad realtor that is waiving inspections on a property like that is largely to blame for NAR lawsuits and other pending litigation. 

If there is not HOA, the only enforcement would be from a disgruntled neighbor who might end up filing a lawsuit against you over a potential Commercial use. 

Although this is technically inaccurate (I saw a case where a sheriff sale of this sort was challenged and the challenge lawsuit took 11 months, deed recording came after that), that is the typical practical waiting period to get the title insurance for the resale.Whatever the mortgage balance, that’s now your obligation to get paid off; before even bidding on any sheriff sale property you should have a good idea of any remaining mortgage balance(s).

I have seen several fail due to lawsuits and insufficent coverage.
