Is this a good decision

[Dan MacDuffie]

I am near the closing date on a house that I am purchasing for 45,000. I am going to use it as a rental and charge 675.00 per month and I have a renter starting Sept. 1st. I put 20 percent down and paid for closing-- the house is move-in ready and they left all appliances.  I am getting a mortgage on the house.  Bank called today and informed me that I owe 13,500 on day of closing-- 20 percent down plus closing cost.  I was expecting closing cost to be around 2,500--Can anyone tell me where I went wrong and is this still a profitable deal? The house was appraised at 46,000--I am starting to question my decision and thinking of walking away.  Thanks for the help- Dan
