I view it as a tool in a toolbox to help you "trim the fat" off the bottom of your portfolio, so you can keep growing with new acquisitions. 

Is there enough fat on the deal.  

Most of the ultra wealthy individuals sacrifice a lot to obtain their wealth, and I won’t make those same sacrifices.Similarly, I don’t desire to have 5% body fat because I don’t want to put in the effort required for it.I understand that ultra wealthy is subjective, but the main point stands. 

For this they get a big fat DO NOT RECOMMEND 

They they get a big fat default judgement against you. 

Up until then I was cheerleading the earlier thought experiments about supporting lean/regular/fat income with ~$1000 / month per paid off SFH, thinking “I could bang that out in 5 years”.

If there are clear signs of negligence (kid throws down, paper towels, food, fats) then you can get the invoice from the plumber with the notes and present it to them. 

You can also ask the title company to offeer a "lean Fee Sheet" meaning "Cut the fat" and reduce the BS fee's.  

How much "fat" do you believe still exists within that? 

I go back to see what I sent them and I had fat fingered an address (389 instead of 380).
