I Just compared interest rate for the 10/1 arm rate and 30 year fixed.
For loan amount $200,000, 20%down.
10/1 Arm rate at 4.5%, lender one time charge is $38
30 year fixed at 4.5%, the lender one time charge is $2726.
Monthly principal and interest payment is $1,013.37.
10/1 Arm is very good choice for current market.
