How to calculate Cost Inflation Index Factor of Residential House property purchased in 1975

How do w know it is 80,000₹? Because the historic cost was recorded. From that you can change it to the current value through index factor. This is normally accounting principle of fairvalue measurement. Asset is initially recognised at cost, then afterwards either at cost or revaluation. 

Thanks for your quick reply , 

The Buyer had paid Rs 80,000 on purchase in the year 1975 in Civil Lines Kota , Rajasthan , land area 2700 sq ft 

Ok fine, 2021 is 301 points, so convert it by 80000*301= Two crores, forty lakhs, eighty thousand, and depreciate it on this amount, 

now the fair value offered a buy is three crores= profit is at taxed at lower level.

On the old price, if you sell it at three crores, humongous profits and higher taxes. 

This method is giving astronomically high and unrealistic valuation , I had attempted it and found not useful 

ANY-OTHER realistic method , please ?

Meanwhile, thanks for your interest  

your correct. The house is fully depreciated in 20 years, 80000*5%*20 years.

The house has no value but the land has. This is how negotiations happen.

Even if we consider cii for 2021 @ 301₹

2,40,80,000

- 2,40,80,000 accumulated depreciation @ 5% for 20 years)

=0

so this woks if there is useful remaining life to assess the building value.

Note: I used slm depreciation rather than wdv as an example. Txs

I agree that now the real cost is that of land and depreciated value of building  

Thanks for your interest in resolving my query 

I have some interesting facts here,

some of the property dealers are selling based on land valuation: https://www.99acres.com/price-estimator

other efficient ma keys have house price index or using % change eg:  2236.46% change is giving approximate value of house along with land value: https://www.nationwide.co.uk/about/house-price-index/house-price-calculator

someone in the business probably knows it more. Txs.

Dear Mr. Ashwin Ranjan, I believe the independent Valuers use hedonic pricing and it’s easy to calculate, By the way, CII indexing= New cii value/old cii value = result*house price. 

So you now can understand cost method which I advisd

 Hedonic pricing- Sales value approach 

Market method

NOI approach 

Normal method = no rules for pricing homes. 

Valuation in a long past year looks bizarre to me .

And Past Valuation of building or property depends (1) cost of a building,  (2) Depends on type of building, (3) Structure, (4) Durability, (5) Location, (6) Size, (7) Width of roads, (8) Types and quality of building materials used and the cost of these materials.

AND all this to get in past year is a herculean task 

Ideas of Ms Yasasvi Gomes look more realistic 

Thanks for Interest  

Lol Mr. Avni Ranjan, there are some countries which charge public for providing stats till 1950’s data. Maybe Bloomberg or should mother business software might have that data. If we could contact them, they will charge exuberant prices. Banks could have that data as well. Or all media real estate association. It’s hard to tell.
