The very first thing you should do when looking to buy a property is to get pre-approved for a mortgage. This tells you how much you can borrow based upon your current financial situation. This can be obtained before finding a property, and is very helpful when looking and negotiating on a property. With this knowledge, you will be able to narrow or extend your search depending on the total funds available.
After finding a property you will need to apply for the mortgage. This is mainly providing documents to prove income, and that you have the resources to repay the mortgage. As a rough guide, the banks require your income to be three times the monthly mortgage payment. This is only a rough guide, and can alter depending on assets, savings or a guarantor for the mortgage.
In most cases banks will lend 60% of the value of the property. This increases to 95% if you obtain insurance through EMI. This does however add to your monthly mortgage payments.
