[Bug?] Tax calculation is wrong when property just purchased

The system seems to be measuring taxed on portfolio change (as of writing - 6 July 2020)When students put a deposit down to apply for a mortgage to buy a house, the deposit money "disappear" from their portfolio balance. Once the house purchase is approved, the deposit money is added back to the portfolio balance. The portfolio balance change is being counted as income and taxed in FULL - which includes the house balance! I have to temporarily the tax module to prevent house-buying students going bankrupt because of taxes owed.Not sure if others encountered the same?
