Sanity Check Help - and Feedback On My 1st Deal

Hi!

I'm looking for someone to run these numbers through their Excel tool (or whatever you may use for evaluating a property) to see if they line up with the numbers I am calculating.  Please let me know what questions you have and any more info you need.

Here are the inputs:

Purchase Price:  $171,000

Interest Rate:  5.125%

Down Payment:  15%

Total Amount Brought to Closing (down payment and closing costs):  $22,875

Gross Rental Income When Bought:  $1,050

Gross Rental Income 1 Year Later:  $2,450

Monthly Water Bill I Pay:  $83

Property Management Fee:  Assuming 10%, but I manage this property for now, so for now it is 0%.  Need to include the 10% for long term growth.

Monthly Taxes:  $338

Monthly Insurance:  $90

To - Date CMA Price: $210,000

I have a ton of analysis run in my Excel spreadsheet (such as monthly cash flow, cash-on-cash return, cap rates, etc.)  I would really like to compare my numbers to someone else's spreadsheet for a sanity check.  If you could please run these numbers and post your results, it would be greatly appreciated!  

It would also be great for feedback on this scenario.  What are your veteran thoughts on this deal?  What advice would you give me for my next deal based on the above deal?
