First you are correct this is a business not a charity or non profit or community service, save community and charity work for the part of you life that you have dedicated to those causes, which by the way is a must if you want to be a complete self actualize person. 

Never ever ever mix friends and family with business unless they are in a dire emergency and you are ok being a charity for them.

@John ReelIf this potential mentor is genuinely doing well at their business, their goal for this meeting is to find how you can contribute to that business.Unless this mentorship is a charity (<1% chance) you will have to add value to this relationship.Ask questions such as.What are we in the business of doing?

Bottom line- This is a business, not a charity. 

And being a landlord is business.. just like when everyone gets on her and says they are not running a charity they are running a business.. well there you go protect your business.. cant have it both ways.land lording no different.. as a property owner or landlord its incumbent on that owner to plan for how they are going to maneuver through tough times. 

Once you apprentice in these occupations and become that top tier your business activities income will give you the means to do what your talking about  travel the world  buy a sail boat  buy an airplane take tons of time with family ( for me start a charity )  or just hang out on BP LOL.    

The main house came vacant and a charity wanted to rent it for a good cause.

Sounds AmazingI was building buildings with a charity worldwide since I was 15My brother worked with tons of local contractorsMy uncle had an extensive real estate careerWill follow your journey and post blogs if I canwould love to see millions of teenagers building houses

I was never in the Military as you probably recall though I put together a charity with a few other BP members called Aheroshome.org and we gave away a fully rehabbed home in Memphis that Chris Clothier did all the work on and we know the quality of his rehabs etc.

My plan is to will my money to a charity in such a way that the principal will survive and the charity will receive a large portion of the annual interest on it to use as funding.
