For the answer to the question above,
For the first mortgage
.8 * 145000 = 116000
PMT = 116000(.0475/12) / [1 - (1 + .0475/12)^(-12 * 30)]
PMT = 605.11091034360862021232175319303
Let's round off the PMT
PMT = $605.11
the 2nd Mortgage
.2 * 145000 = 29000
2nd mortgages are usually interest only payments
I = 29000(.07525/12)
I = 181.85416666666666666666666666667
$181.85
605.11 + 181.85 = 786.96
..........................................
for the second option
PMT = 145000(.0525/12) / [1 - (1 + .0525/12)^(-12 * 30)]
PMT = 800.69536810575262261015659677087
PMT = 800.70
800.7 + 58.3 = 859.00
