My personal home is at 1800 feet elevation and on spetic tank.

There is definitely risk there if the interest rate market turns or rents tank but I am ok with that risk.I will definitely be feeding it the first year but I did take some cash out of the deal in order to fund some of those challenges. 

My 1991 properties are great now but it would still hurt if I bought a few and they tanked.

You'll be running the risk of getting bad reviews and that will tank your business.

Used to read Inc magazine all the time...now Shark Tank ha ha. 

Something I don't think enough people mentioned is that you have all the time in the world to invest after college, but I wouldn't want to look back and wish I had finished my degree if lets say the economy tanks, you run out of deals or financing opportunities and need an income.

You should go for a property that would be a home run, not potentially tank your cash flow. 

But precious metals are about 1% of my net worth and it gives me peace of mind to know that i could sell it off at a premium if/when my real estate and stocks tank again.

My investment properties could tank tomorrow and I wouldn't be foreclosed out of my home, that is a very powerful safety net imo. 

@Brooklyn R. just an FYI you can legally own bazookas and tanks - and what do you know no one ever commits crimes with them.
