John and Sally Claussen are contemplating the purchase of a hardware store from John Duggan. The Claussens anticipate that the store will generate cash flows of $79,000 per year for 20 years. At the end of 20 years, they intend to sell the store for an estimated $490,000. The Claussens will finance the investment with a variable rate mortgage. Interest rates will increase twice during the 20-year life of the mortgage. Accordingly, the Claussens desired rate of return on this investment varies as follows:

Years 15 8 % Years 610 10 % Years 1120 12 %

Required:

What is the maximum amount the Claussens should pay John Duggan for the hardware store? (Assume that all cash flows occur at the end of the year.) (Use PV of $1 and PVA of $1) (Round "PV Factors" to 5 decimal places, intermediate and final answer to the nearest dollar amount.)
