This paper aims to clarify problems about separating the ownership of skeleton and infill in skeleton-infill housing (SI housing) and to propose solutions of them.
It is one of the barriers of skeleton rental housing that the ownership of infill is interpreted as being absorbed into the ownership of skeleton in present Japanese civil law and cannot be mortgaged for housing loan. To solve this problem, we studied the system for skeleton rental housing which uses leasehold.
The result of studies is that it is possible to mortgage the leasehold for housing loan and to trade in the leasehold freely in housing market.
