Just to add to some of the comments above, you can force cash flow in LA with some sweat & upfront investment (cash & time).

You can also use sweat equity and/or self manage whereas these are not options in the 401k. 

Value adds present a method of achieving sweat equity that can provide a higher value asset at a lower cost which can improve cash flow.  

Used sweat equity I built up from my first "House-Hack", ADU, BRRRR deal.

You can put in sweat equity.

Looking for multis to hold and opportunities to lend sweat, cash and equity (and pickup truck).

I will throw this out as well, if you have and qualify for a Roth, you can do it in a Roth as well, and never pay tax on the gain, the biggest challenge to any of these are the cost of a QI is high, you cannot put "sweat equity" in, and can't draw any profit till you draw retirement.

So, I guess it depends on you, as the wholesaler, what you want to invest in and how you want to protect that investment (time, money, blood, sweat and tears).I believe that transparency and ethical behavior from the wholesaler is imperative.

As an individual  who has invested 30 years of sweat equity, savings, & due dilligence into a high quality  beautiful  home, I stand by my right to protect  myself and my property. 

Don't sweat flood insurance.
