10 Things to Do Before Applying for a Mortgage

If you want the short answer so you can get on with your day, here it is. Before you even think about viewing a property, you need to check your credit file for errors, get registered on the electoral roll, and pay down as much unsecured debt as you can. You also need to gather your last three months of payslips and bank statements, cut back on silly spending, save the biggest deposit possible, and avoid applying for any new credit cards. On top of that, stay in your current job, speak to a broker, and get an Agreement in Principle. That is the list. But if you want to actually get approved without tearing your hair out, you need to understand the details because lenders are incredibly fussy these days.

Buying a house is stressful. I think it’s consistently ranked as one of the most stressful things you can do, right up there with divorce and losing a job. It is a lot of money. The bank wants to be absolutely sure you can pay it back. They aren't just being difficult for the fun of it. Well, sometimes it feels like they are.

Check your credit report first

You might think your credit is fine because you pay your phone bill on time. That’s not enough. You need to see exactly what the lenders see. Go to the main agencies like Experian, Equifax, or TransUnion and download your statutory report. It is usually free or very cheap.

I once found a missed payment on my file from a mobile contract I thought I’d cancelled three years prior. It was a nightmare to sort out. If I hadn't checked before applying, the bank would have just said no.

Look for mistakes. If there is an incorrect address or a financial association with an ex-partner you are no longer with, get it removed. Disassociate yourself. You don't want their bad habits dragging your score down. It’s about being clean on paper. Lenders love boring applicants. Be boring.

Get on the electoral roll

This seems like such a small thing & yet it causes so many problems. Lenders use the electoral roll to verify who you are and where you live. It is an identity check.

If you are not registered at your current address, it screams "instability" to a lender. It can cause delays or straight-up rejection. It takes about five minutes to register online on the government website. Just do it. If you aren't eligible to vote in the UK, you should add a note of correction to your credit file explaining why.

Pay down your unsecured debts

Lenders look at affordability. They don't just look at what you earn. They look at what you have left over at the end of the month. If you are spending £300 a month on credit card repayments and another £200 on a personal loan, that is £500 less you have for a mortgage.

It lowers your debt-to-income ratio if you clear these. It makes you look less risky.

Try to clear your overdraft too. Living constantly in your overdraft suggests you are struggling to manage your money. Even if you are within your arranged limit, it doesn't look great. It implies you rely on debt to buy groceries. That makes lenders nervous.

The paperwork mountain is real

You are going to need a lot of paper. Or PDFs. Start gathering them now because hunting for a P60 from two years ago when you are under pressure is miserable.

Generally, you need your last three months of bank statements and payslips. You need your latest P60. You need proof of ID like a passport or driving licence.

If you are self-employed, it is harder. You usually need two to three years of accounts or SA302 forms. Lenders want to see stability. If your income fluctuates wildly, having these documents ready allows a broker to explain the story to the lender before they make a decision.

Watch your spending habits

This is the part where it feels a bit intrusive. Lenders will go through your bank statements line by line. They are looking for red flags.

What is a red flag? Gambling transactions are a big one. If the lender sees regular payments to betting sites, they might think you have a problem. It signals risk.

Also, look at your subscriptions. Do you really need all of them? Excessive spending on non-essentials can impact your affordability assessment. For the three to six months before you apply, try to live quietly. Be frugal. It shows you can manage your money and have disposable income. It might seem unneccessary to cancel a streaming service to get a house, but every little bit helps the affordability calculator.

Save a bigger deposit

Cash is king. The more you put down, the less you need to borrow. This changes your Loan-to-Value or LTV.

If you buy a house for £200,000 and have a £10,000 deposit, that is a 95% LTV. The rates for that are usually higher. If you can scrape together £20,000, you are at 90% LTV. The interest rate drops.

Lower rates mean lower monthly repayments. It saves you thousands over the life of the mortgage. If you are close to a threshold—say you have a 9% deposit—it is worth pushing hard to get to 10%. The difference in the deal you get could be massive.

Don't apply for new credit

This is a classic mistake. You are excited about the new house, so you go and buy a sofa on finance. Or you lease a new car.

Stop.

Every time you apply for credit, it leaves a "hard search" on your file. Too many of these in a short time looks desperate. It drops your score. Plus, that new monthly payment for the sofa reduces your affordability for the mortgage. Wait until you have the keys in your hand before you apply for anything else.

Stability in your job matters

Lenders hate change. They want to see that you have a steady job and a reliable income.

If you change jobs just before applying, it can cause issues. Especially if you have a probation period. Many lenders won't lend to you until you pass probation.

Going self-employed is even riskier right before a mortgage. You go from having payslips to needing two years of accounts. If you are thinking of quitting your job to start a business, maybe wait until after you have bought the house. Timing is everything here.

Get professional advice

The mortgage market is huge. There are thousands of deals and every lender has different criteria. Some hate self-employed people & others are fine with it. Some mind if you have a small deposit & others don't.

You can go to your own bank, sure. But they can only offer you their own products. They won't tell you that the bank down the road is 0.5% cheaper.

It is often better to use a broker. Consulting a mortgage advisor Peterborough based expert ensures you have access to the whole market and can secure the most competitive rates for your circumstances. They do the legwork. They know which lenders are likely to accept you and which ones will waste your time. It saves a lot of stress.

The Agreement in Principle

You can't really go viewing houses without this. An Agreement in Principle (AIP) or Decision in Principle (DIP) is a certificate from a lender saying that, in theory, they would lend you a certain amount.

Estate agents want to see this. It proves you aren't a time waster. It shows you have the funds ready to proceed.

Getting one usually involves a soft credit check, so it doesn't hurt your score. It gives you a budget to work with so you don't fall in love with a house you can't afford. That is a heartbreak you want to avoid.

Final Thoughts

Getting a mortgage feels like jumping through hoops while someone throws paperwork at you. It is tiring. But if you prep early, it is manageable.

I remember feeling sick the day I submitted my application. I was worried about a £20 charge on a bank statement or whether my signature matched my passport. But because I’d done the prep, it went through.

Be boring with your money for a few months. Get your files in order. Speak to someone who knows what they are doing. It is worth the hassle when you finally turn that key in the door of your own place.
