Proving cost of improvement

ProgTick (N/A) (100 Points)

Long term capital gain - how would one prove cost of improvement without bills? I read somewhere that in such case, one should have income tax approved valuer estimate the cost and such. The changes were made in 1981-1982. Will a valuer be able to give an estimate for that time? Where to find such valuer?
