Some city code departments have regulations about height.

One thing I would add, if you truly believe they are involved in criminal activity then I would make a report with your local police department.

If someone leaves, the others have to come up with the rest of the money and sue the departed tenant.

I will say call the local police department, Housing or do additional research as needed.

Tried to submit per BP Rental Property Calculator, a report with 7 CAP rate, to a local credit union's commercial loan department which had approached me earlier for business.

Typically only community banks and commercial departments at credit unions will be flexible to this.The exceptions are national hedge fund based mortgage products like Colony and others that will be able to make one note (mortgage) to you securitized by multiple trust deed's (what you're asking for above from multiple states).The problem you'll encounter is local community banks or credit unions which only want to securitize properties in their state (single state) or if they have a larger foot print (regional player) then they will only securitize properties typically in their footprint (unless if you have a really good relationship with them).I noticed you said you had one in CA and one in WI, I'd probably go with a "Colony," type hedge fund lending product on that specific request.There are others out there that I've seen but nothing off the top of my head at the moment.Best of luck,

You also have a legal obligation to try and procure a new tenant as quickly as possible to reduce the obligations of the departing tenant.

Thomas, tomorrow you really need to call the Department of Health and have them come out and do an inspection.  

In this state, it is the Department of Business Regulation.
