Eligibility of payment towards purchase of flat u/s 80c

Dear All,

I have purchased a flat in Jan,2017. I have made a part payment of Rs.100,000/- as token money for purchase of flat to builder through cheque in Dec,2016. Total value of flat is 780,000. However sale deed is for 6,50,000/-. I have also incurred Rs.46,000 towards stamp duty, registration fee. (34,000 in cheque, 12,000/- in cash). I am about to pay society maintenance charges, service tax amount and other amount to builder around 60,000 in Feb,2017.

So, How much amount can be claimed as deduction U/s 80C. Also Share your view  can i take the benefit of dedcution for differential amount paid to builder (Purchase value- Agreement value), other amount of Rs.60,000/-

Request to reply as early as possible.

Thanks,
