When they move out a few cosmetic things like cleaning, new carpet and fresh paint will boost the rental income substantially. 

everyone says hi, the lawns are always freshly cut, it’s clean great school district, etc...

I have one that we use in our car detailing business (it was $500 and would struggle to be effective with anything larger than a bedroom, so definitely RENT the larger one you'd need), Running mine for an hour in a freshly detailed cigar smoker's car with the AC running and you'd never know it had been smoked in.

Pre-babies, I competed in long-distance triathlon and I needed 8 hours minimum to recover from brutal training sessions and to be fresh for the next one the following day. 

The fresh air is amazing, and "biking for dollars" is fun :) I also love personal finance and geeking out on index funds and compound interest :) I'm learning first hand how much knowledge everyone I meet has to offer!

I would dive deep into one of those and then practice it daily to keep that skill fresh.

First if you are looking for deals on Zillow which is ok but you have to realize that the "deals" on there are not fresh to begin with.... 

Unless you have connections there is absolutely no way you’re making that kind of money as a driver fresh out of CDL school.

During this time 3-4 years,  I never lost my job and it actually helped me to get out again and start fresh in my different path.

I get how fresh paint, a power wash can go a long way, but most of what I've seen need more than that.
