The Commercial is important later if you get into new construction, remodel & flip or hold, or 5+ unit properties.  

Repairs were invoiced/ completed, then 4 days later I received a notice from sec 8 inspector that said that there were power surges all over the house: when she turns on basement stairwell lights, the stove power goes out and when turning on hallway light, the fan goes out in the bedroom, with 30 days to repair.

Sooner or later the right property will come across your lap and you will take action. 

Customer came back a some time later to our business to patronize us.

Hiding that from tenants is a big mistake and comes back to bite you later.

Think of all the things that could go wrong and see if the lease addresses them: unauthorized pets or tenants, early termination, security deposit, lease violations, late rent, eviction, lawn maintenance, parking, etc.5.

I asked the guy if I can take a picture of it and he said yes and insisted that I sit in it, and when I did he told me start his car, when I tried to it didn’t start, the battery was dead, he asked me to give him a jump start and I did, after that he took my phone number and about a week later he calls me and offers to buy me a beer.

You could split it from the start, but you might risk clawback if things go south later.

I have seen those who do ugly things make it big for a while, but have it all come crashing down on them later.
