There are 3 properties, so my math says that's one lot that is vacant.  

The math that I'm doing doesn't show that I'm saving that much buy switching over to a fixed loan.

The only reason being psychological.Unless some math wiz says different, I believe it doesn't make any difference.

I am curious to know how people run the math on a "facelift" for a buy and hold rental.In my case it is a $55,000.00 property. 

By your math, factoring capex and appreciation and blah blah, you are losing money.Your note is $725 + $110= $835.Rent = $925My 2nd grade math shows $1080 per year profit. 

By my math that's more than 5,500 gallons per day.  

But, for instance, using the $4,200 a year earned on the Bigger Pockets "Real Math" example (https://www.biggerpockets.com/renewsblog/2013/01/1...), how do you turn $4,200 a year into something you can live off of? 

  $200-$400 to sign a document stating they are officially moved out/terminating there lease, and give you the keys.I know that can be hard on the ego but this is about math, not ego.

You can do the math, but make sure you think through and have a solid plan before you quit your day job to go sit in the beach sipping fruity drinks and map out your plan to get rich investing in real estate if you don't have a LOT of money to invest.
