Roth 401(k) vs brokerage account

[Derek Zeigler]

Alright so What is the benefit of contributing to a Roth 401K vs self investing in a taxable account granted you have the discipline to invest. I am looking to invest more in RE and like the liquidity that a non 401k provides if I were to want it to put into a deal. I may be looking at it wrong but a 401K seems great for people to start with and for people not financially disciplined to actually save that money once they get it. Let me hear your thoughts.

About me: 31 yrs old, married with 1 child. net worth about $500K with just over $300K in investments. Max out roth 401K and roth IRA for last 2 years, Total income last year $176,000
