I purchased my grandparents home and 18 acres 22 years ago, granting them a life estate. That ended in 2004. The house was resurveyed and split off with 1 acre in the same year and has been vacant until 2020 when it was rented. I put all sorts of money into fix up, repairs, basement waterproofing, new furnace etc. over the years before it was rented. Added A/C once it was rented. Can any of the money spent prior to it becoming a rental be used as an expense for 2020?
