For a generator to be capable of even just sustaining itself (not providing power to any external elements), it would have to achieve perpetual motion.

Well said, there were a few other design elements that did not make the post.  

We lived in HOA and needed to pay several hundred to send out hoa disclosure package send a certification to buyer that property was in line with all hoa rules, another expense I forgot about. 

A portfolio Loan on a package like this would land around 5.5% to 8% interest 

I was offered 2, four-plexes as a package deal, for 385k.

Amazon packages are regularly stolen off of porches. 

Find a lender and get their package of costs, points fees, and find a deal that makes $ with that in the mix, and flip a house...

Our most recent purchase included a package deal for 3 SFR, all 2 bedrooms and a fourplex for a total of $66,600 for the package.

They have packages down to even owners with a single unit. 

I expect there are some in the "for sale - join my investing course for $2000 to $50000" packages, but I would think there has to be something out there to get started with that doesn't require 3000 hours of reading to piece-meal from 3000 topics.At any rate, more importantly than that, for all of you heavy hitters and longtime investors that have seen it all before, what would you tell yourself to watch out for, if you could go back and tell yourself when you were just getting started to be watchful for?
