Plan to rent it out after I move, looking for improvements to make to increase rental cash flow.

What those features are depends largely on neighborhood and on what's important in that neighborhood, and whether you're improving the property to flip it or to rent it. 

In Massachusetts, it would be equal to a 4 credit college course, so in Connecticut, it would be equal to a 6 credit college course.As much as technology is out there like YouTube with real estate videos; there is no easy way other than "Just Hitting the Books" without the technology is the best way to learn pen, paper, 10 key calculator, your textbooks and allocated study time and quiet space will help you succeed! 

Code § 453 (l) (2) (B) (ii) (II) which states "any residential lot, but only if the taxpayer (or any related person) is not to make any improvements with respect to such lot."  

Every 6 months or so, move into another unit, fix it up, and raise the rents in the unit(s) you've already improved.

The owner is talking about liability insurance.ALso....try to buy it or lease option or something...the owner is ok with you doing the work as you are improving THEIR asset. 

Measure your progress, reward yourself for even tiny successes.Watch YouTube videos – Bigger Pockets, *************, Grant Cardone, Ted Talks, Dan Lok, Tony Robbins, Robert Kiyosaki, etc. and don’t stop until you’re succeeding in creatively maneuvering yourself – better - leveraging yourself into a better position.You can do it, somehow you will find a way.

Either to improve the appearance or to treat mold.Any idea how we should evaluate this variable? 

I've watched few real estate investing videos on Youtube and all of them are saying you can buy a house for lower price than the market and put down payment on new house with the difference (equity?!)
