Thinking about Mortgage Preparation? If you’re hoping to buy a house, then you’re no doubt well aware that you need to be saving up for a deposit. But there are other important steps you can take to prepare your finances when applying for a mortgage. We’ve laid out the key actions that can make the difference in getting approval from a lender.
First, check your credit score. Is it correct? Is it a good score? We cover what you need to know about credit scores, including how to check your own and what to do if you need to improve your score in our blog: Everything you need to know about credit scores.
Next, look at your credit facilities. Do you really need any credit cards you have? And if you do, are the limits higher than you need? Same question for any overdraft facilities you have? The bank won’t look at whether you use your credit facilities, when calculating your income they’ll assume you’re maxing out your lines of credit.

These days, lenders often want to see that an applicant’s current spending habits would support a mortgage. It’s standard to provide your previous three month’s bank statements as part of the application process.
To budget for a mortgage, talk with us to find out what you can borrow on your income. We can also tell you if you’d qualify for a loan at 10% or less, this will inform what your minimum deposit will need to be.
Then, you can use the Platinum Mortgages’ mortgage calculator to find out what your weekly repayments would be. Use an interest rate of 8% for example – Minus from that amount, your current weekly rent. The difference is then the minimum you should currently be saving each week.
For help budgeting, we recommend Sorted’s budget tool.
Once you have your deposit saved, we can sort a preapproval for you. A preapproval is a document provided by a lender that specifies how much they are willing to lend to you, and is generally valid for 3-6 months. With a preapproval you can start house hunting with assurance, but note that the lender will need to approve any property before you go unconditional.

Once you are in the process of getting preapproval, it’s a good time to ensure you have room in your budget to cover the costs of purchasing a home. These costs usually include:
Looking long term, there are ongoing costs to owning a property that you don’t have as a renter. Common costs are:
