There are many reasons for this, too much to write here but, in a nutshell, the economy is a mess, inflation is not under control as the fed would like you to think and the housing market along with all other markets escalated so fast and high in such a short amount of time that it created the largest debt bubble in history, it's not sustainable and 2023 will be the beginning of a long and deep recession.

Others have told me to withdraw the money and put it into something more sustainable such as real estate.So my question is, is it worth keeping the 401k option, or can that money be better invested through real estate? 

I told him to tell the buyer that he would be. 95% of the when you have an agent acting in an unethical, illegal, or just ******** manner, the threat of an ethics or commission complaint will be enough for you to get them to so what you want (assuming you are the one in the right.

How do you sustain a onsite manager? 

It may take you a year or more to really build a sustainable business and if you don't have savings or minimal expenses when you are starting you may be derailed into something else.

Then one guy in the group was saying how real estate is not sustainable, and that things go downhill quickly, yada yada.

Are there strong economic indicators to sustain this market over the next 10+ years?

I’m entrepreneurial and relatively risk-averse, so as I’m building my real estate portfolio I’m looking to build my own network of friends/partners to walk with me as I find potential good deals in a manner that will be profitable but conservative.

We sustained a massive fire.

My goal is to build my portfolio in this manner and buy at least 1 door every 2 years here in Los Angeles.
