Landlords may require licensing and vaccinations for assistance animals if that is what is required by local law for domestic animals." 

@Theresa Harris The new restrictions state that the home must only be used as a "single family" home, defined in their terms as either an individual or a group of individuals related by blood, marriage, adoption, fostering, civil union, domestic partner, or other "parental or connubial relationship".

My issue is that if since my entity in only filed domestic in NY, do I need to file a foreign entity in the other states in order to close in them? 

As Ahmed referenced, if you register an LLC in Illinois, you would/could register that domestic LLC as a foreign LLC in Indiana

I mean, asbestos, mold, rodent infestation, animal feces, human waste, a hoarder, illegal aliens, bad plumbing, the electrical was shot, drainage problems, warrants for tenants, regular police contact, found stolen property stashed, drugs, needles, tenants on the run from the police and not paying rent, one died while on the run, domestic disputes with another tenant, a illegal grow room, permitting issues, contractor problems.

Additionally, I had compressed air blown through the domestic water lines to completely clear them.The buyer wanted the water turned back on for inspections which is a reasonable request.

He was 1) Ticketed for domestic disturbance, 2) Has harassed the tenants upstairs for making too much noise [they are now moving out], 3) Was 30 days late on March rent due to the government shutdown [was able to get rent assistance from the County], 4) Smokes in the house [though I have no way to prove it], and 5) Told me in December that he needed to terminate his lease early because of the noise upstairs, but hasn’t been able to find a new place for the last 4 months.

One thing for sure is the cost of living and Gross Domestic Product (GDP) is going anywhere but UP.  

Who Must File Domestic Partnerships Except as provided below, every domestic partnership must file Form 1065, unless it neither receives income nor incurs any expenditures treated as deductions or credits for federal income tax purposes.
