a property owner has set up a contract in which he agrees to sell a warehouse 5 years from now to the tenant who currently leases the space. the tenant has agreed to continue to pay $20,000 in rent at the end of each year, including year five, at which time he will purchase the building for an additional $1,500,000. assuming the required rate of return on a similar investment is 10% (annual), how much is this deal presently worth to the original owner of the property?
