must solve this query

Dear experts. i hav bought a flat from builder. i started giving Rs. 100000 annually since 2000 as installment to builders. but possession was given to me in 2008. after that i have incurred Rs. 200000/- in 2009 for painting etc of house.
My query is: can i claim indextation on the installment paid at the time of sale? will this be allowed yearwise? will Rs. 200000/- paid for painting be treated as renovation etc and indextation be allowed?
pls reply if sure also quote the section.
thanks in advance.
