I'm current a junior in college and majoring in business marketing.

I have some friends who are in the STR business in Flordia I can definitely make an intro.  

I was hit by an 18 wheeler 2 years ago - my fault- and tried to start a business last summer that didn't succeed, which it shouldn't have, being that I hated every minute of mobile detailing, and I recently got to where I am at least head above water, but I am paycheck to paycheck.

Just want to get a fuller picture as to the overall timing from application process to actually getting the cash in to my hands to actually conduct the purchase.

I understand that notes is a business best learned by doing, but I am trying to lay a good foundation of knowledge as a starting point.To date, I have read these books:"Invest like a Bank" by Beaux Blast" Little Green Book of Note Investing" by Fred Moskowitz"Real Estate Note Investing" by Dave Van Horn"Note Investing Made Easier" by Martin Saenz"Invest in Debt" by Jimmy Napier"Profiting from Non-performing Mortgage Notes" by Amed HazelI welcome any thoughts or recommendations that the group may have.   

Similarly, the initial losses in a new business should be viewed as the "tuition" necessary to gain invaluable experience and skills in a new field.

They won't be advertising online because they are already busy.

If 2 business owners create a contract, are their signatures enough to make it a binding agreement or would getting the contract notarized be a wiser decision?

I am a busy doctor with some cash I have been saving for truly passive investment opportunities as I am limited with time right now.

Do this as a course of business and you may well be violating brokerage laws.
