FIRST PROPERTY NEED HELP PLEASE

[Jason Chambers]

Ok, so i was wondering if I'm missing anything on the first numbers i have ran on an actual property.  Let me give you a rundown of how it went.  

listing price 169k

cash to close would be 11129

month rents are 1350

prop tax 95 

insurance 101

mortgage would be 730

vacancy 135

repairs 35

that brings me to 1096 of expense

then i took my income (1350) - expense (1096) = 254 in cash flow 

that would make my annual return 3048

then take that 3048 / my initial investment 11129 = 27%  

I'm just making sure these numbers are correct.  Im wanting to make the leap and start investing but i need to double check my numbers. now the taxes and insurance are spot on i received quotes.  can someone help me out and let me know if I'm missing something. that return seems really high
