The Simpsons are first time home buyers.They have negotiated a fixed rate of 3%, compounded semi-annually, on a $325,000 mortgage loan to be amortized over 25 years.The Bank of Canada posted 5 year rate is currently 5.34%.The Simpsons expect that monthly municipal taxes and heating costs will amount to $300 and $150, respectively.Their only other debt is a $10,000 line of credit which they have yet to use.The couple's gross combined income is $115,000.

They will make monthly mortgage payments.Note that mortgage lenders assume a minimum (usually 3%) payment on a credit card balance and line of credit balance based on full usage.
