I have posed this question to them “Are you people going broke ?”

The fact is, he broke the lease once and he will do it again when it suits him.

We found out the property was broke into at 4 am yesterday and the newer furnace/ac were stolen along with some damage to the hardwood floors and the front door where they pried it open with a crow bar. 

(Q2)Another question I have is that since Steve broke the terms of the lease by affecting the other tenants’ “peaceful and quiet enjoyment of the property”, is he obligated to pay the rest of the rent even though he will be vacating the property before the end of the lease?

The college girls are very sweet. 2 play sports on scholarship and work and have told me they pay their own way with their scholarship money, loans, work etc and have good references from previous landlord and credit score. 

Meanwhile, I'm talking to this guy and he said in his other property, the little old lady paying long term rent, moved out, and within a week, the neighborhood people had broken in, had a party, broke most of his doors, stolen all his copper and HVAC, etc.

If you can just turn boys to girls and vice versa there is nothing that cannot be done other then the limits of our technological capabilities.  

In any case, "rental arbitrage" is almost 100% done because the lessee is broke as a joke and couldn't muster up bus fare home, so they use someone else's asset in order to cover for their lack of resources.

Where do you think we get the saying if it ain't broke, fix it until it is.... 

These are packaged up by brokers to look pretty, but make sure you read the fine print before you ask that girl to dance.
