Investing time and energy in getting educated is well worth it.

For example, California's commercial energy rate in November 2023 was $.2314/KwH, while in Las Vegas, it was $.1128/KwH.California - The exodus of people and businesses from California is another factor to consider.

You can always pay for mentorship, but I have found that mentors that you are willing to put your time and energy into are everlasting. 

Lots of young investors, good energy, easy networking.   

Improving energy efficiency not only helps the environment but also puts money back in your pocket.

We're going to update some of the landscaping, tidy up some of the lighting in the common spaces, work on some fresh lines in the parking lot, etc / etc / etc.

Real Estate requires time, energy and expense. 

You would want to be able to cover a major expense without using that ideally but you can in a pinch.Don't overlook dollars to pick up pennies; a mutually beneficial seller finance deal for a good property is an amazing opportunity and I would put my energy into that first.
