Abstract: Methods and systems for implementing investment options on a real property. An owner of the real property may sell a Call option that gives the owner a consideration in exchange for an option to purchase the property at a strike price at some point in the future, wherein the strike price is set to a percentage of the initial fair market value of the property. The Call option may also give the owner the right to participate in the net appreciation of the property upon sale. The owner may purchase a Put option that gives the owner a stop-loss in the event of a market downturn or the depreciation of the property's value. By placing a Collar, a bundled Call and Put option, around the real property, the owner may diversify his/her exposure to market downturns in exchange for a piece of the upside.
