New member and his calculations

[Karoly Holczhauser]

Hi members and friends, 

My name is Karoly and I am a brand new member on this website. Within a couple of month I would like to purchase my first fourplex property. As you can see I am a brand new player in real-estate investment, so I just started to read Brandon Turner's book: Rental Property Investing. As per his recommendations I started to evaluating deals. One/two deals per day.

I started creating my first excel sheet yesterday, but the numbers are not make any sense, I see that my CoCROI and other ratios are very low. I would highly appreciate if someone could download this excel of mine and check that am I doing the right thing? Did I make any error during the calculation? In case you have any suggestion, please let me know! As a beginner all I can do is one thing: LEARN :)

Thank you all very much,

Karoly
