What about a doubling of the current inventory within 12 months screams "hot market" to you?

Also with FHA and the little amount I'm putting down, most of the numbers for the properties don't make sense. (1800 gross scheduled income for a loan of 180k is not making me scream up and down and does not give me much positive cash flow)I'm wondering if I should just look for a cheaper property and buy it without living in it.

Unless you're getting a screaming deal on it, I would definitely think about it more.

There is part of me that sees the ROI and screams at you to take it, but there is a whole other side to the coin here. 

If a tenant is screaming at me about something, I just shut up, let them say what they want to say, and then address their issue in a  professional manner.

This was a deal he probably shouldn't have done: his "gut" was practically screaming at him to not to do this deal from the get-go. 

I would invite him over for a glass of ice tea ( it's bloody hot here in Florida and it's the polite thing to do ) then I would in a calm voice explain that had he come to you like a good neighbor, you would have been happy to pay the hoa for a year possibly even up to 5 years but because of his rude and illegal actions you are not going to on principle, also if he files a lien on this property again without just cause when you go to sell the house or harasses any potential buyer about this or any other issues he might think important.

It was like all those people who that screamed they will move to Canada if Trump was elected.

I think just staying on top of things and being persistent sent this guy the message that he wasn't going to be able to take advantage of me and I got him out without any need for legal fees, yelling and screaming, or (so far) trashed apartments.

I've rented to families that state they will only smoke outside and this has never happened.If the family has kids running all over the house slamming doors and screaming during a showing, this is a bad sign.
