Answer:
the minimum price depends on the owner's discount rate. For example, if the discount rate is 12% per year or 1% per month, then the price should equal:
PV = $1,000,000 x 90.81942 (PVIFA, 1%, 240 periods) = $90,819,420
You would need to adjust the PVIFA depending on the owner's discount rate; the higher the rate, the lower the price.
