International Real Estate Review


Housing mortgage finance in India is constrained by the maximum loan-to-cost ratio and installment income ratio conditions imposed by housing finance companies. The typical reason for this behaviour is that the market for the sharing of risk in mortgage lending is not yet fully developed. Mortgage insurance plays an important role in developing this market. The objective of this paper is to present a case for mortgage insurance market in India. This paper develops a mortgage premium structure framework in which mortgage insurers charge an insurance premium that equates losses to revenue.

This paper also models mortgage termination due to prepayment and defaults. We contend that the termination of mortgage in housing is not as `ruthless’ as OPM theory would suggest, primarily because households are not financiers in the `stricter sense’. We have used the Cox proportional hazard model to analyze prepayment and default of mortgage behaviour in India. The results indicate that financial concerns (like the option price, loan to value ratio, and monthly principal and interest to income ratio) are important determinants besides household characteristics. The cumulative prepayment or default probabilities from these models are used in the estimation of the insurance premium structure.
