A formal home loan is onerous to subprime borrowers in efficient markets. This can deter
homeownership for financially strapped individuals, leading to a market failure. This paper
proposes a special form of cooperative mortgage financing (practiced in Oman) to overcome
this market failure. We integrate the literature of mortgage design with that of informal
savings schemes (i.e., ROSCAs/ASCRAs) to illustrate that this mode of financing dissipates
credit risk better than the formal mode of financing. It is also resilient to volatility of interest
rates and allows prepayments without any additional charges. Finally, we verify the
assertions of Besley et al. (1994) and Hart and Moore (1998) that cooperative mortgages
are pareto-superior to formal mortgages in special cases.
