Deductions & credits

Yes, you would split the cost basis and selling expenses in half.  Each of you would report half of the sale.  

It's not clear from your comments whether you lived in the house.  The instructions below assume you and your brother never lived in the house.

Cost Basis:

• As indicated your cost basis will be the fair market value (FMV) on the date of death and since it was sold shortly after death the selling price could be considered as the FMV.  For this reason there will be no real gain and possibly a loss when taking into considerations the selling expenses.
