she has to borrow .8(229000) or $183,200

for Credit Union:
i = .034/12 = .0028333...
n = 20(12) = 240

paym(1 - 1.0028333..^-240)/.00283333.. = 183200
I get a paym of $1053.10 per month

balance after 5 years
= 183200(1.00283333)^60 - 1053.10(1.0028333..^60 - 1)/.0028333..
you should get $148327.00

Since I don't live in the US, I have no idea what is meant by
" a 5/1 ARM at 3.25%"
