I have received inherited residential flat of my father which was purchased at approx Rs. 18000 (Eighteen Thousand) in 1980 in mumbai, area 265 sqft. In 2007 the building got extended and so the flat extended by 110 sqft. I have transferred 50% share of my flat on my wife's name, now we are joint holders. If I sell the flat for 65 Lakhs how much tax will be calculated on sale of inherited property. Request you to kindly guide.
