The closing costs for a buyer should be no different on a short sale and I’m assuming you are buying a short sale. I’m not looking at the HUD1 but having down dozens of them this is what is typically done. There are 2 sides to the HUD1, the buyer side and the sellers side.
Under A the 2,350 is typically on the buyers side but the number sounds high and should be lower than the owners title insirance. The sellers side typically pays the owners title insurance and should be the higher amount.
Under B the $2,000 in 2nd half taxes are the taxes due from date of closing until June 30,2011 so you are pre-paying your taxes not the sellers.
As for the rest of the fees it really depends upon your loan fees and when you are closing. if you close at the beginning of a month you have to re-pay interest for the rest of the month, hence the reason most people prefer to close at the end of a month.
In summary without seeing the actual HUD1 its its unusual that you would pay impossible to say I would ask about those title charges. Call escrow not the listing agent/office.
