A plot of land was allotted to my father by the Housing board on leasehold basis. This plot was transferred to me by my father and was registered in my name for value of Rs. 38,000 in 1992. In 1994 I constructed a house on the plot investing Rs. 3.3 lakh. Later in 1994 I further expanded the accommodation with investment of Rs. 1 lakh. In 2008, the leasehold was converted to freehold but the registration value remained at Rs. 38000. Now I want to sell off the property. For computation of capital gains, what will be my cost of the house, I have taken part loan from my employer and remaining as saving & personal loans so what documents will be required for the basis of cost and what will be the document requirement of IT deptt along with my tax return.
