jimthompson5910 (jim_thompson5910):

the part " 4/1 ARM" means that for the first four years, the interest rate is fixed at 3% after the 4th year, the interest rate will increase by some amount every 1 year

jimthompson5910 (jim_thompson5910):

the portion that says " 3/7 cap structure" means that the interest rate will increase by 3% each year and it will increase a max of 7% overall (through the life of the loan)

OpenStudy (anonymous):

woah lol ok.. now what

jimthompson5910 (jim_thompson5910):

yeah it's a lot to take in

OpenStudy (anonymous):

haha im still learning but you always explain very well

jimthompson5910 (jim_thompson5910):

the key thing to take away from it is that you start at 3%, then you increase by 3% to get to 3+3 = 6% interest rate for year 5

OpenStudy (anonymous):

gotcha

jimthompson5910 (jim_thompson5910):

the overall increase is maxed out at 7%, so you just add this to the initial interest rate to get your final interest rate

OpenStudy (anonymous):

ok

jimthompson5910 (jim_thompson5910):

so what's the max lifetime interest rate? ie the final interest rate

OpenStudy (anonymous):

im trying to calculate i cant seem to get the answer .

jimthompson5910 (jim_thompson5910):

just add the initial rate to 7

OpenStudy (anonymous):

whats the initial rate ?

jimthompson5910 (jim_thompson5910):

jimthompson5910 (jim_thompson5910):

OpenStudy (anonymous):

jimthompson5910 (jim_thompson5910):

look at my explanation and tell me the initial interest rate

OpenStudy (anonymous):

3%?

jimthompson5910 (jim_thompson5910):

yes, add that to 7% to get your second answer

OpenStudy (anonymous):

jimthompson5910 (jim_thompson5910):
