When you buy a house, lending institutions review your financial position before approving your mortgage loan. They usually recommend that the total of the monthly principal, interest and tax payment doesn't exceed 30 per cent of your gross income.
To determine monthly principal and interest payments on a specific loan, consult a mortgage table. You'll need to know the interest rate, amortization period (length of mortgage) and amount of your down payment.
But buying a house involves a number of other less obvious costs. It's these unexpected costs that put many consumers in a difficult financial situation.
