Business 101- find a need, fill a need @Lorien Rollins could probably help you with the basics 

I updated the bathroom/porch in the spring, and am finishing construction on a 2-stall garage (the previous garage was basically a large shed that I could not fit much in).Moving forward I am considering one of the following options to put my money and build equity:1.

Sounds like the house is basically New just needs a new tenant once this one moves out and then there's plenty equity in the deal. 

"Smart money" was responsible for the 10K bitcoin current comeback basically.

My basic philosophy is that if you can't handle the little things, then you can't handle the big things.

So for 10k its 33 and if your self managing basically C class rentals thats a full time job maybe not full time but its anything but passive.

Another thought you could just keep the tri-plex and gift them the net income each year...it's basically the same thing without any transferring. 

The advice is very basic.

For example - you're starting a $100,000 remodel on a propoerty that you have acquired, the Scope Of Work includes basic lipstick stuff like a kitchen remodel, a bath remodel, and new flooring and paint.I would start with a draw of no more than $10k, that is more than enough to get anyone going and it shows your good faith.
