@Andrey Y.You missed missed the real time post by heavy weights Jay Hinrichs and Grant, but you can read in post. 

And in between it could be a combination of matrix with varying weights of importance.  

You don’t want to be overly weighted one asset class.

Still weighting the pros and cons of use a heloc from you primary residence to fund deals.

And by the way, having your weight under control alone isn't a sign of healthiness.

I do apply the same general rules about weight limits.

:)BTW, I said I carried boots in the car/truck, also had light weight overalls to put on over casual clothes, might need to crawl under a house, get in an attic or walk through brush.

Is your overall wealth over weighted in Real Estate.  

Those two books especially Muilti-Family Millions have so much useful information in them they're worth their weight in gold.

Luckily gold went up a lot in that time.It's extremely liquid.An important thing to keep in mind is that gold coins don't have value just for their weight in gold (of course that would not be true in the oft-lambasted apocalypse scenario).
