I chose real estate because of the massive wealth building potential given the proper time and skill, and because it just made sense to me compared to some of the other options out there.I'm very new to the real estate realm, so there's a whole world of learning ahead of me.

figure out what sets well with you and take massive action. 

All cash = massive risk.

All of the construction I have seen in Los Altos has been scrape and build, with a trend in full basements for either entertainment rooms or massive garages. 

You would want to hold onto it and wait for a better market to sell it in UNLESS 1) selling it will relieve you of a massive headache and is worth the loss in cash, 2) selling it will allow you to invest funds in a bigger and better deal (happy scenario) or 3) some life circumstance happens and you just need cash bad, for medical or a home emergency (sad scenario) - people are selling stuff at a loss everyday because they really need/want the cash for something else.  

I get the partnerships where it's one finance/design person and one contractor type person; but how are 4 people each generating massive value?

For context, this is our only rental property and currently cashflows close to $750/mth and we're looking to capture the massive appreciation, free up all the equity which is roughly $200k (currently have heloc but as investment prop could only get a line for 25% of equity), and use the cash to purchase a few other properties outside of the crazy Boston market.

It looks like the Fed may finally begin unwinding it's massive balance sheet, which rose from less than $1 billion before 2008 to over $4.5 trillion(!) 

There is a REIA meetings (two separate groups) at Bradenton Yacht Club on Tuesdays at 12:30PM and one in Sarasota at Oriental Buffet on Bee Ridge on Wednesdays at noon.  

But they loved the place as it was walking distance to the Mandarin Chinese Buffet with senior rates & had a bus stop out front.
