They are not always happy about spending money, but thank me when I get a higher selling price than what they expected.

Outside of real estate, I enjoy spending time with family.  

Second is that you can be disciplined enough to take the money that is left over and not spend it on "stuff" so that you can have it to put down on your next property that you are going to house hack and that you will do it when you get to your next destination this summer or fall.

I’d join the brokerage that is the best fit personality wise for you and spend all my spare time networking.

If you want to spend the money you can consider triple pane.

Like @Jesse Rivera mentioned above, I also go to a few sessions but spend most of my time in the lobby or at the bar making connections."

Whether you spend time networking, reading books, watching videos or connecting on bigger pockets or if you spend cash hiring a mentor, maybe partnering up with or doing free intern work for a real estate investor; whichever route you decide to go investing in yourself is one of the best investments you can make. 

But on this specific guy, I jumped on a call to explore the program and it was a high pressure sales call, it did not feel organic, not trustworthy and certainly did not feel the right fit.Why would someone spend 10k on a so niched-down space of real estate when they can get someone for the same amount to teach him/her everything?  

While I did spend about $15K on renovations, that amount doesn't need to be factored in for this discussion.

Spending a healthy % for a reliable company can make your life easier and lead to more growth as you free up your time.
