When you apply for a mortgage loan the bank officer doesn’t ask you about your future plans, but rather about your current finances.  He is not interested in what you have planned and what financial needs you may have later on; his concern is whether you can pay now or not. His decision, on whether your loan is approved or declined, is based on current financial status.  But although your credentials may get you an approval for a high value house, you may not choose to go that high up, though the bank officer will tempt you, because the higher the loan, the more the interest you will pay.  You can avoid temptation and buy wisely using the mortgage calculator, because you can calculate the installment that best suits you in line with your future plans, and make a wise judgment about your property purchase.  The mortgage calculators can you give you a break-up of the loan and all details will be shown clearly and simply for you to understand.
