we have sold our flat at mira road for 26 lac which was bought for around 6 lac in 2000 but thru a loan,,which is now been closed, now we are using that money to buy a new house at grant road for 37lac but that is not considered a flat (i think not sure )though it is in an old building, but the toilet is a common one on all the floors, now how much tax do i need to pay for that, and if possible how should i save the tax, kindly advise
