And, the two people living with him are now wanted for aggravated assault.

Talk to a local real estate attorney to see if it's worth the cost and aggravation of pursuing it. 

Without bringing up the lease again and aggravate him even more as he wanted to talk to his attorney (according to what he said/presented he is a kid with rich parents with attorney), what some other ways to minimize the situation (ensuring no random security issue / damages on house and car), get my garage and driveway back, and get him to leave peacefully as soon as possible?

Remember, it will still cost a lot of your time/money/aggravation to defend a lawsuit that you may eventually win.

The amount of money at issue is small and the time and money that will be spent, coupled of the aggravation if things go south, may leave you more bitter and financially injured in the long run.

They hear the words private placement, see fancy offering materials, and watch rousing deal webinars and they get that excited (premature) bowel movement feeling.The financial protections (net worth and/or income) from the high risks of private placements are important and just having the knowledge part may not be sufficient protection. 

In most cases, you'll save money, time, and aggravation trying to figure out the intricacies of the Internal Revenue Code on your own.  

Also, if you switch loan providers now consider how much money you will loose to Wells Fargo and factor that in to see if it's worth your time and aggravation to find a new lender. 

ØAs its already mentioned by bottom house landlord that it was not that day’s issue,it just aggravated on that day.

But no, I have to go check each time which is aggravating.
