Deductions & credits

My mother passed away and did not have a will. In her state the next of kin can claim her property and get the deed in our names (my brother and I), but we choose not to "assume the debt" with the mortgage company and just paid mortgage while we still resided in Florida. We did a quick sale to her best friend and received no money, but her attorneys sent both my brother and I  a 1099-S form for 7500.00. Am I suppose to claim this on my taxes??
