Comparative rent is the primary method of evaluating the fundamental value of any property. The price-to-rent ratio links the cost of ownership with the cost of rental. This link is direct because possession of property can be obtained by either method. The cost of ownership encapsulates all of the financing terms and other variables associated with possession of real estate as does the cost of rental. Price-to-rent ratio fluctuates over time as changes in the cost of ownership and terms of financing makes financing amounts vary and house prices vary as well.
