On the Pricing of

Shared-Appreciation

Mortgages





        by Frank H. Page and Anthony B. Sanders*




     This paper examines the impact of housing-value uncertainty as
     well as interest-rate uncertainty on the pricing of shared-apprecia-
     tion mortgages. Compared to a model in which housing values and
     interest rates are certain, the introduction of housing-value uncer-
     tainty lowers the share of appreciation required by the lender. Simi-
     larly, the introduction of interest-rate uncertainty lowers the share
     of appreciation required by the lender. If housing values and inter-
     est rates are positively correlated, a shared-appreciation position can
     be combined with a fixed-debt position in order to hedge against
     both housing-value uncertainty and interest-rate uncertainty. If
     housing values and interest rates are negatively correlated, the com-
     bination of a shared-appreciation position and a fixed-debt position
     will result in a highly speculative instrument.



I. Introduction

    Recently, French and Haney [1984] examined the pricing of shared-
appreciation mortgages under the assumption that housing-value
changes are stochastic. This assumption allowed them to extend the
seminal work of Dougherty, Van Order, and Villani [1982] who did not
allow for uncertainty with regard to this variable. By incorporating un-
certainty about housing values, French and Haney discovered that
lenders would charge a lower share of appreciation relative to the share
obtained by Dougherty, Van Order, and Villani under certainty.
