ICICI Pru Home Assure is a single premium term insurance plan. As per company website -
If I foreclose my loan or transfer it to another company?
Surrenders will be payable only in case of full prepayment or balance transfer of the loan. The surrender value will be calculated as:
1- 70% of the single premium * (outstanding term at surrender / original term).
2- The surrender value will be payable only if the amount is not less than Rs. 250.

So you will only get 70%. As you have just took the home loan in year 2008 and only 3 year since you started paying the premium, I would wait. 3 more years so that I would get the benefit for 6 years, which is 30% of 20 Years. So that what ever amount I had paid, I have recieved in benefit.
