Personally speaking, Housing Loan is the cheapest loan one gets.
We Indians are petrified of INTEREST cos are dada, pardadas have seen zamindari system and fall prey to it as interest rates were as high as 4-8% per month.
So the saying, Jitni chaddar utne hi pair failao.
But off lately, i would only suggest to use this interest portion to set off against 80C and 2L additional exemption.
Now i can suggest you a trick where all interest gets exempted, and for business owners saving tax even if interests are more than 10-20-50Lpa by just paying 1.5% income tax of total interest.
