Can you share details on generic unit economics to use for something like this? 

I don't fault Brian for seeking a way to supplement his business.

I wonder if you could answer some of them more generically or perhaps offer questions that investors should be asking of syndicators in general.

The letter is a generic letter stating we pay cash for houses in any condition, blah blah blah. 

I do not pursue RE investing for financial freedom as I love my job and what I do, but I am interested in supplementing my income and net worth with active RE investing.

I have very little Real Estate investing knowledge but interested in learning about wholesaling, lease options, buy & hold to supplement my income.  

Learn as much as you can yourself and supplement with coaching courses and mentorships I was just a little turned off by you asking in the first post how much he would pay you to learn that.

I would like to begin investing in buy and hold rentals with the hope that as my kids get older and we have more of them I will be able to supplement my income to provide for them and help them get started with their future when the time comes. 

My current goal is to look for properties for cash flow to help supplement retirement income in the near future (possibly 4-8 years from now.I could extend that time frame).
