user: I'm evaluating several mortgage options and need to calculate the monthly payments for different loan scenarios: a $350,000 loan with a 3.5% interest rate over 30 years, a $500,000 loan with a 4% interest rate over 20 years, a $750,000 loan at a 2.5% interest rate with a term of 15 years, and a $1,000,000 loan at a 3% interest rate to be paid off in 10 years. Could you provide me the monthly payment amounts for each of these loans?
