Short sale and became sheriff sale

[Dida N.]

Hello,

I gave an offer on a short sale  since December 2015... I waited until march the bank responded with encounter they offered me, while I offered another encounter  the house went to sheriff sale , the bank bought the house less then I offered, and now i'm the first on the list to buy the propriety but they said they will add sheriff sale, attorney money... closing cost and if seller has any IRS amount , need to be paid.... al this is great

My question is those charges for sheriff sale, attorney, closing cost and IRS payment .... do I have the right to see each payment detail ? or they just give me the total and I need to agree without knowing the detail? do they have the right to do that? the bank bought the house sheriff sale as 250k and now they want me  to pay $275k The house appraised for 290 K

Thank you,
