Hello,
You can purchase a new house property within end of previous year in which property is sold or within 2 years in case you invest that amount in capital gain account scheme till the time the property is not purchased.
In said case you can avail two benefits as deduction from sale value of property :
1. Indexation Cost of House Property Purchased in the year 1998 in place of original cost of purchase
2. Total Value of Purchase price of New Property
If you can give me exact figure than i can do proper working of capital gain and let you know taxability on it.
In case of nay further quarry you can contact me on
