Question $2$: Forecasting ARM rates Question $(30$ points$)$

Adjustable$-$rate mortgage amortized over $30$ years, with an LTV of $80\%$ and a $4\mathrm{.}50\%$ teaser rate. The

margin rate for this loan is $3\mathrm{.}15\%,$ and the index rate is $4\mathrm{.}00\%.$ Assume the index rate increases to $4\mathrm{.}30\%$

at the beginning of year $3.$ Early repayment charges apply within the first $3$ years of the loan at $2\%$ of the

outstanding balance. The property you're looking at is priced at $$800,000($ignore acquisition fees$).$

What is the interest rate on this loan in the following years $(9$ points$)$:

a$.$ Year $1$

b$.$ Year $2$

c$.$ Year $3$

To fill in the table, calculate the monthly payment and the outstanding loan balance of the ARM at

the beginning of year $1,$ year $2$ and year $3.(18$ points$)$

Calculate the repayment charges if the property was sold after $2$ years. $(3$ points$)$
