Buying of property from capital gain fund

Dear Sir/Madam, Our family had long disputed property which has been settled out of court recently from which I received sum of Rs 28 Lakh . When enquired about re-investing I realize that I can utilize these fund for buying property only until then I should park this sum in capital gain account in nationalized band and use it for buying properties in next two years or I should buy government bonds which yields 6.5% annual return as a interest for 3 year. Now my questions are a. what are different legal options I have to get more returns on fund which I possess? b. I dont have my own house so far, Can I invest only in land and later I can construct a house ? c. If buying of house or flat is mandatory , can I look for land which has old tiled house or farm house where the house value is negligible and land carries the more value ? d.Can I invest on agricultural land ? e.What kind of tax structure is applicable ? And your valuable advice please Regards Girish
