Here's one of my first calculator builds, it's not the holy mecca but It works.

I have written about my investments quite extensively in a series of blogs starting with Have I Found the Holy Grail of Passive Real Estate Investing?

People who think they have found the holy grail of money-making, and all they have to do is buy a property and start counting their piles of money, Scrooge McDuck style. 

That comes` out by the insinuations made in that book  you're holding as some holy grail, it's guru stuff and does not teach real estate, fair or ethical dealing or legal implications of being an operator in real estate. 

I am a Tech Exec that decided about 6 months ago to dive in and research the holy heck out of how to best approach shifting half my investment capital to real estate from just Stocks and Mutual funds.I put my 4, 10 and 20 year goals together and then built a plan on how to hit each goal.Then I started networking and learning everything I could here, books and networking with friends and other investors.I initially landed on just going for appreciation in my town of Austin.  

When I realized I could get $350 a night for my condo, holy cow, all of a sudden going to work wasn't so bad.

The holy grail for me would be 2/3 bed, 2bath, garage, yard or pool SFR under $2800 a month. 

Holy smokes!

Oh my friend TREAD LIGHTLY HERE your in Nor Cal in the bay( I think) AND UNDER RENT CONTROL, Holy moly !!!!!

That's the holy grail.
