Type your answer here...1. Interest paid on loan will not form part of cost of acquisition. However registration fee paid will form part of cost of acquisition
2. No, you don't need to reinvest entire sale proceedings. You need to reinvest only capital gain subject to the fact that both old and new properties are residential properties.
Capital Gains shall be exempt to the extent it is invested in the purchase and/or construction of another house i.e.
1. If the entire amount is equal to or less than the cost of the new house, then the entire capital gain shall be exempt
2. If the amount of Capital Gain is greater than the cost of the new house, then the cost of the new house shall be allowed as an exemption
3. Yep...it make sense to sale the property in April 2016 because of indexation and cash outflow of tax. Time available for reinvesting is irrelevant here. as it is calculated from the date of transfer.
