I have purchase a house for 148 lakhs jointly with wife in Nov2019  I  invested my retirement benefits and saving. 

After 10 month in Sep 2020 I have sold my flat for 48.75 lakhs.   Can I use this lcapital gain  for claiming the tax saving  as it was BUY first  and  SELL later with in 1 year.

If it is acceptable  can I build a new house in my  site for 50 Lakhs.  some one said that If I construct a new house with in in three years , capital gain  saving will be canceled. Other said is it applicable only to 84F  case not for section 84.

Please clarify
