Quote from @Randall E Collins: This post is directed toward professionals who know real estate in and out.

Feel it best to diversify into a few to manage risk and liquidity. 

Determine how much money would be needed to handle each risk, and determine if you have sufficient liquidity / cash flow to ensure you can “stay in the game”.This is of course in addition to all normal “due diligence”, financial forecasting, etc.

I have well over 10K put aside liquid.

I remember him mentioning it multiple times in the podcast, but I can't remember the specific book, can anyone help me out here?

My business partner is getting a divorce and rather than split things up we have decided to liquidate soon.

As it stands today, I have roughly 70k liquid and looking to invest in building a new construction home for profit.
