You currently lease land to graze livestock. Your lease is up this year, and the landowner has offered you a $15-$year contract to lease the land for $$55\mathrm{.}25/$ac for $15$ years, with the first right of refusal to buy it at the end of $15$ years for $$850/$ac$.$ You want to counter offer to see if the landowner is willing to sell the land to you today instead of the lease agreement. The landowner values all investments at a $6\mathrm{.}5\%$ interest rate. How much would you have to offer to purchase the land today for the landowner to accept your offer?

Note: This assumes the landowner is indifferent to selling today vs$.$ selling $15$ years from now.
