Adam is approved for a 25-year 6/1 ARM at 4.35% with a 4/14 cap structure in the amount of $308,400. Assuming Adam is charged the maximum interest rate, what will his monthly payments be at the beginning of the seventh year? $1,431.85 $1,688.04 $2,080.06 $2,291.86

the interest is held fixed for 6 years, then goes up 4 points each year (not to exceed 14 points in all)

OpenStudy (anonymous):

determine the payments for the first 6 years to define the balance after 6 years then restructure the loan for the remaining time at +4 points interest

OpenStudy (anonymous):

payments for a 25yr, fixed loan of .0435 will give us the initial period payments amounts Po = 308400k^(12*25)(1-k)/(1-k^(12*25)), k=1+.0435/12 B6 = 308400k^(12*6)-Po(1-k^(12*6))/(1-k), k=1+.0435/12 use that for the remaining time (25-6) years at .0835 P1 = B6 k^(12*19)(1-k^(12*19))\(1-k), k=1+.0835/12 and sorry this is taking so long im in a class right now =(

OpenStudy (anonymous):

Po = 1688.04 i believe

OpenStudy (anonymous):

B6 = 261 595 if im not correct dont hate me

OpenStudy (anonymous):

i see i typoed P1; that last fraction is flipped the wring way =( P1 = 261595 k^(12*19)(1-k)/(1-k^(12*19)), k=1+.0835/12 = 2292 or so
