Advice on Capital Gain Tax savings while selling Landed property

Dear Sirs, I am having a landed property in Thrissur ,Kerala. As the same is not getting sold , we are planning to start a joint venture with a builder. There will be a huge capital gain tax burden when we sell this property. To avoid that we are planning to buy another small property with a house and remaining amount to invest in Government bonds. But we came to know that maximum in a year, we can depositRs. 5,00,000/-in these bonds. Sale of the JV project will be completed within 2 years only. We would like to get your advice on how Tax can be managed in this case. Sales price of Landed property will be around Rs2.7 crores and purchase price of new house will be Rs92 Lacs. Purchase price of the land for sale was only 9 Lacs about 20 years back. My main queries will be as following 1 ) With a part of the sales proceeds of this property ,can I buy one house and can the balance amount invested in bonds like NAHAI, which give interest? 2 ) As the sales proceeds will be distributed to several instalments spreading for 2 years, is there any problem in managing the tax? 3) will there be any capital gain tax , when we withdraw the amount from bonds after the stipulated period of 3 years? What are the other probable risks and problems which I may face in this transaction? Please connect me to your Chartered Accountant Expert on the phone for discussing more details. What will be your charges for this advice? kindly inform Regards, Shyam.T.G
