Real estate is an amazing vehicle to pave your way to success!

Real estate is a long-term wealth vehicle, and overall, I would be cautious about how you define overpriced.

Has rent control worked anywhere on the planet or fails every time in the short & long-term.Why not have price control on college tuition, food, interest rates, new vehicle prices and energy ?

So while real estate can be a great vehicle - realize it’s cyclic - and you are in the high side of cycle.  

You have never seen it, and do not understand that tax returns reveal all, and the credit report it just one of many ways debt is uncovered and a LLC is simply a vehicle for a business just like any other self employed business. 

Is there a financial vehicle where I can park that money and only pay taxes when I make withdrawals? 

Lots of legal opinions here, but most are inaccurate.It is true that, absent an estate planning vehicle (trust, etc.) there needs to be someone with “standing” who is empowered to pass title.
