A farm is being offered for sale at $4,000 per acre
A buyer thinks he can come up with a down payment of $1,300 per acre and he hopes to finance the rest at a lower interest rate. Approximately how low must the interest rate be for the net profit of $150 per acre to meet the loan payments on a loan of $2,700 for 20 years?
If the interest rate remains at 8%, would it do any good to increase the length of the loan in 3 above? If yes, how long? If no, why not?
