Most professionals will recommend a separate LLC for every $1 million in assets but I don't think that's necessary.

If you have millions of dollars in assets with a bank and are a private banking client, they will likely take a loss on your jumbo mortgage and give you a killer rate to keep your assets with them.

Congratulations on breaching the $1 million net worth milestone!

That's why for the OP, I say just invest in the broad stock market and retire with millions in 20 years.

I sell between $500 to just under a million dollar homes. 

. $25k to $1 million, 10 year draw.

We got super lucky... we spent about $1 million dollars buying the 25 properties we bought back in 2018-2021.  

You will lose your collateral/land ($1 million). 

On real property purchases I went from $50,000 to $500,000 to $1 million +.
