So I took the gamble, At age 19 I was a landlord, I loved it.

Even worse, you can have to deal with an eviction.Like many investments, you can use gambling formulas to look at this problem.

Though, I know it would be a gamble.

I probably should have a larger deposit, but since I'm living here too, I just gamble at hoping that they won't damage much with us both living in the same house.

Do you really want I gamble on what a jury could rule?

It's a gamble but most stocks are gambles since we don't the "real" story of a company.

But it is a gamble, and at the least you have something to get you around town!

It is a mathematical fact that if you are buying a rental property in any city where the monthly mortgage payment exceeds monthly rental income, or where mortgage payments along with monthly expenses exceed monthly rent, if any of those scenario applies, a down payment would be only other material method to avoid a negative cash flow situation.You let the investor worry about his gamble on the market going up.. thats not your problem.

I would have started learning about investing in RE in college rather than gambling on stocks while taking notes.If I have the knowledge and drive back then I might have skipped a party to buy a house or two. 

NOTE that you are gambling that the Interest Rate will AVERAGE 6% for the HELOC.
