One house is sold in PY 2021-22 so agreement was done in PY 2021-22 but full consideration was paid in PY 2022-23. Hence the transaction will be considered in PY 2022-23 but for calculating capital gain which year's index rate is considered? Stamp duty & tds payment was done PY 2021-22 however sale is considered in PY 2022-23.
