This paper develops a theoretical model of the problem of maintenance
risk in reverse mortgages (RMs) and home equity conversion instruments
generally, By maintenance risk, we refer to the incentive homeowners
will have to reduce maintenance expenditures as their equity in the ho
use falls during the term of the RM. The underlying reason for this te
ndency is the limited liability feature of RMs, given that a borrower'
s obligation to the lender at maturity is limited to the value of the
house. The results of the model show that lenders will respond to this
problem either by limiting the amount of RM loans to guarantee that m
aintenance risk is not a threat, or by charging an interest rate premi
um to cover the expected cost of default. Unfortunately, there do not
exist data to test the importance of maintenance risk as a possible li
mitation on the extent of the RM market.
