Do your own itemized income/expenditure calculation and be sure to include both medium and long-term commitments such as loans, and your monthly household expenses.
The mortgage provider expects you to pay off your loan within a set period - usually 25 years, so your age is going to impact how much you pay each month.
But before wading into the property market it might be useful to know a little more about mortgages.
Remember, this is not a decision that should be taken in haste - you will be spending a fairly large portion of your remaining years paying off that mortgage, so make sure that you can afford the repayments without adversely affecting your quality of life.
Most lenders will have a guide to what documents are required on their website.
It is also extremely useful to have a letter from your chosen financial institution that indicates your pre-approval status. In fact, many sellers (and real estate agents) will not take any offer seriously until they see proof that you can afford to buy.
Once you have identified which lenders suit your needs then chat to a representative - and ask questions.
