The present invention is directed to a method and system for allowing a customer to purchase a house at an affordable price, where the house has been leased to the consumer under mutually agreed terms between the consumer and a leasing company. More specifically, the method and system facilitates a financial service alternative to conventional financial services, which enables a consumer first to select a house to lease and then optionally to purchase the leased house at a fixed residual purchase price during or at the end of the lease term. The consumer is directed to select a market available “for sale” residential real property to be leased. The selected house is initially purchased by a home leasing company for providing the alternative financial service on the selected house. The residual purchase price is determined based on the acquisition cost plus an appreciation factor based on lease terms and qualifications of the consumer.
