If not again you would be better off buying your own home and having enough yard/space for all of them but 13 is still way to many dogs unless you live on a farm or own acres of land.I have worked in the banking business and have seen people lose their homes that they rent due to landlords kicking them out with very little warning due to breach of contract or a No pet rule. 

No warnings, just terminate if possible to gret rid of this problem tenant.5) Theft of tenant possessions - ignore.- Have they filed a police report?

I know in Virginia my friend had a similar issue (side-by-side duplex, though, not second floor) and he was not proactive, just warning them several times verbally.

By the way, if you do speak to the previous landlord and they are not forth coming, that's a warning sign!

But I know several people who made this mistake even after I warned them including someone who dumped 3M into a fund that promised to pay 10% return. 

They warned me I'd take a hit on the algo.

If weed is illegal in your state, call the cops every time, issue a written warning, demand a short-notice inspection, etc.

If you're going to work with contractors, collect rent from tenants, or try to bed the hot chick at the bar, you better learn to recognize warning signs and get out early. 

Despite only renting for two months, this tenant's aggressive behavior is creating a hostile living environment for other residents.Specific Issues:He complains about our lack of notice when entering the property during our own move, despite prior notification.He has moved items around the house without permission.His communication has been condescending and confrontational.He installed a surveillance camera in a common area, violating the lease agreement.He banged on the door because he couldn't use the smartlock code properly.Considered Actions:We plan to serve him with a notice to vacate.We are considering having a constable with us when we serve him the notice.Questions:Should we just give him warnings considering that his actions may not improve?

Warning: Schedules C claiming expenses without any income are not against the rules, but they are IRS audit flags.
