The acceptability of property for inclusion in institutional portfolios relates to many factors. One is the nature of the lease contract. Over the three decades preceding the 1990s, a lease of 20 to 25 years on full repairing and insuring terms and let at rents which are reviewable upwards only became the accepted institutional 'norm', but research has shown a fragmentation of lease terms emerging during the last decade, reflective partly of recession and partly of changing occupier needs. At the time the institutional lease developed, leisure properties were not generally included in institutional portfolios but remained in operator or specialist ownership. Over recent years, however, new styles of leisure properties have been developed which have begun to enter investment ownership. It is believed that one of the reasons for this lies in the type of leases which leisure operators on the new-style 'leisure parks' have entered into. These are believed to fill the 'norm' in ways possibly less achievable by investors in other types of properties. The paper details some of the characteristics of the newstyle leisure developments and presents findings of a pilot study of some new-style leisure leases. It argues that these do indeed meet investor requirements, although in a way which might present longterm difficulties to the occupying lessees. If this is so, it concludes, the long-term effect for the investor could be negative.
