What not to do before applying for a mortgage - 7 mistakes to avoid when applying for a mortgage

Updated: Apr 6, 2023

So, you’ve started to look at properties and mortgages.

You’ve probably read loads of articles telling you what to do before applying for a mortgage, but what about what not to do? In this blog, we’ll go through 7 things you should avoid doing in the lead up to your mortgage application.

Here’s what not to do before applying for a mortgage!

Failing to check your credit score

Your credit score plays a big part in your mortgage application, so it’s important to know where you stand. Checking your credit score early in the process will mean that you could have enough time to adequately boost your score if necessary, which could have a big impact on the success of your application.

Getting into debt

This one is fairly self-explanatory. A lender will want to know if they can trust you to repay your mortgage loan, so they will look into your financial history to check your incomings and outgoings, making sure that you would be able to meet your monthly mortgage payment without any stress. If a lender sees that you have recently taken on extra debt to pay back, then they could regard you as a risky borrower which would hurt your chances of getting a mortgage.

Making a huge purchase, e.g., New Car on a loan or a holiday purchase on a credit card

A lender will look at affordability and a large outgoing or more debt to service means that potentially your affordability will be lower as you’ve now got a large monthly commitment.

Changing jobs/ going self-employed

We can usually find a lender for every situation but changing your job could restrict you to fitting with fewer lenders. Sometimes you just can’t help it, but if you can, avoid switching jobs before/during the mortgage application as it could limit you to only dealing with lenders that allow that. Should you choose to become self-employed when applying for a mortgage this is much more of a problem. You’re no longer employed so you can’t use that income even if it was only from last month, as you no longer work there. When self-employed, most lenders will require proof of income averaged over the last 2 years (there are a handful that will allow just a year) to show steady income, so not being able to give lenders what they need to prove your income may result in you having to wait a couple of years! Talk to your broker to understand your options.

Making large deposits

Getting a deposit for your first home is hard, we get it. Your family members may want to help you out and gift you some money towards your deposit to assist you on moving out of their house! Be careful as there are rules about what constitutes a family member and it’ll need to be carefully and properly documented, but don’t worry, we have templates for this scenario.

If you are hoping for help from family members, the lender and solicitor will need to be able to trace that money so using Nan’s cash from behind the sofa could be problematic!

Not making payments on time

As we have said before, the lender wants to know that you are responsible with money and that you are capable of meeting your monthly mortgage repayments. If a lender sees that you have multiple missed payments, whether it’s a rent payment or a phone contract, they will assume that you won’t be able to pay a much larger debt, such as a mortgage back on time and you may face a challenge being accepted by a lender.

This could have a big effect on your mortgage application, some lenders can be very strict with gambling and could be wary about applicants with a history of gambling, which could lead to your application being unsuccessful. The odd bet here and there shouldn’t harm your mortgage chances, but if you are spending large chunks of your income on gambling then it could be more difficult for you to find a better deal. Not all lenders will be super strict on gambling, however, and they will take certain things into account, such as how often you’re gambling and how much you’re gambling.
