Thanks for the Info. I'm just a little confused about part of the reply. The question was not about taking the 2020 expenses as a deduction which the information provided seems to address - and I realize that I cannot do - but rather adding said expenses in the year of sale (2020) to the cost basis of the sale to reduce the capital gains realized from the sale. It's mathematically equivalent under some, but not all, circumstances but not necessarily procedurally equivalent.
