I sold my vacation home in 2017. I am a surviving spouse and have a FMV determined for my husband’s estate. I rented the holiday home in the summers after my husband’s death and depreciated the property based on the FMV from my husbands estate. I have the orginal cost of the purchase as well as the improvements made before and after my husbands death. I live in Maryland. It is my understanding that I get to use half of the cost of the original purchase price, half of the improvements cost before his death and have of the stepped up FMV. My question is when do I apply the depreciation number? The depreciation was after my husband’s death. Also, can I use 100% of the improvements cost after my husbands death.
