I tolerate it because I am paid to.

An asset's [the note your brother would hold, secured by the flip that you may botch, is an "asset"] risk premium is a form of compensation for investors who tolerate the extra risk [investing in flips at all is a risk, going to 100% LTV is a HUUUGE risk] - compared to that of a risk-free asset - in a given investment.Most people do not have a lot of assets in literally "risk free" places like a federally insured savings account earning 0.1%/yr.

Working for the 'big guy' you also learned about risk tolerance and limmiting exposure.

I don't tolerate being lied to or disrespected.

That's a great idea--listening to the podcast will definitely make my commute on 66 more tolerable!

Each approach carries with it a different level of risk - and with any other investment your risk tolerance is what is the biggest factor.  

In Reality, if we equate Cash Flow with Liquidity, in other words, the higher the Cash Flow the more you consider the Investment to be Liquid, then it's a fair argument.However, if your Risk Tolerance is set to a point where you cannot stomach a level of Cash Flow that is at break even, then this kind of Investing is not for that person.In the case of my property portfolio, Appreciation is not about the Value of the Property as it increases ONLY.

Rental must use better quality subfloor material taking up the tolerance and able to keep animal urination.

I've discussed this with a lawyer, I am able to evict based on my zero tolerance for criminal activity addendum, but an eviction with a physically aggressive person doesn't sound like a great idea.

I also have high risk tolerance, though I'm open to learning from anyone here (including those who would strongly advise against this).Thank you for your time!
