Tax question…I have been leasing out my famillies house out since their passing in 2007. I had been using a figure of 100K for depreciation. ( I realize now I should have had it re appraised at time of death reflecting a more accurate vale, an oversight of mine) I have since sold the house for 405K in 2020…I did pay for appraisal work done earlier this year and appraiser valued it based on 2007 market which was 325K …If it is cost effective to do so do I have any recourse? Thanks for any insight into this …I truly appreciate
