We bring in our vulnerabilities to grow, and take the steps within their system making it happen.  

I think you have a conversation with your brother that starts with humility, vulnerability, and honesty.

I didn't skip your statement about vulnerable position of real estate investment.

One might even argue you are more vulnerable going full turnkey PM as you will have zero visibility on your investment until you actually visit it since you will be at the whims of whatever the PM thinks is best for your asset.  

Please explain the vulnerability.

After years of refusing to change their tactics, the Realtors’ agreed to a settlement now because they were vulnerable to government action.

I get the less leverage aspect makes you more vulnerable to the underlying house price, but the lack of debt gives you the ability to maneuver around that & its likely a high house price point will appreciate more than the average over the long haul but these are just two years in, you got to wait till really year 8 to start trading the equity. 

Big jury award in a personal injury type lawsuit, or spouse and/or children wresting control away from you when you get older, or one bad deal for one property bleeds over the makes the others vulnerable, or you find yourself unable to pay huge tax liability at some point and want to be judgment proof on paper so IRS cannot seize assets and has to do an offer in compromise with you?

We basically have two options as a for-profit company: A: scale massively with huge overhead (like we were doing at 50 deals a month at times at MartelTurnkey) or B: leverage our experience and success to train others how to be profitable with micro flips and be less vulnerable to market volatility and shifts.

However, if you're looking for payment reliability, I'd recommend a slightly different strategy that aligns well with consistent income.Partnering with non-profit organizations that support vulnerable populations, like the Veterans Affairs or groups assisting people with developmental disabilities, could be highly beneficial.
