Top Mistakes to Avoid When Applying for a Mortgage

Applying for a mortgage is a big step towards owning your home, but it’s not always a straightforward process. Even small missteps can lead to delays, higher costs, or even rejection. At ABC Mortgages, we want to help you avoid the common mistakes that could stand between you and your dream home. Here’s what to watch out for and how to get your application right the first time.

Not Checking Your Credit Score Before Applying

Your credit score plays a huge role in determining whether a lender will approve your mortgage and at what rate. Some applicants apply without checking their credit report, only to be surprised by issues like missed payments, defaults, or even errors on their file.

How to Avoid It

Check your credit report before applying. Agencies like Experian, Equifax, or TransUnion can provide free checks.

If your score is lower than expected, take time to improve it by clearing debts, paying bills on time, and avoiding new credit applications.

Dispute any inaccuracies on your report. It’s easier to fix them before applying than to explain them to a lender.

Not Getting a Mortgage Agreement in Principle (AIP)

House hunting without a Mortgage Agreement in Principle (AIP) means you don’t know exactly how much you can borrow. This can lead to disappointment if you set your sights on a home you can’t afford—or delays when making an offer.

How to Avoid It

Get an AIP before you start viewing properties. It shows sellers and estate agents you’re a serious buyer.

An AIP gives you a clear idea of your borrowing limit, so you can focus on homes within your budget.

Overstretching Your Budget

It’s tempting to go for the most expensive home you qualify for, but borrowing at your maximum limit could leave you financially stretched, especially if interest rates rise or unexpected expenses pop up.

How to Avoid It

Be realistic. Factor in other expenses like council tax, insurance, utilities and maintenance costs.

Use mortgage calculators to see how different rates and terms affect your payments.

Making Big Financial Changes Before Completion

Many buyers don’t realise that lenders continue checking financial stability until the mortgage is finalised. Changing jobs, taking on new credit or making large purchases (like a new car) could lead to your application being re-evaluated or even declined.

How to Avoid It

Avoid major financial decisions until after your mortgage is completed.

Keep your spending habits stable. No sudden spikes in debt or big credit applications.

If you must change jobs, inform your mortgage broker first as it could impact your eligibility.

Not Shopping Around for the Best Deal

Some buyers assume their current bank will offer the best mortgage deal, but sticking with one lender without comparing options can cost you thousands in the long run.

How to Avoid It

Work with a mortgage advisor to access multiple lenders and find the most competitive rates.

Compare fixed vs. variable rates to see what suits your financial plans best.

Look beyond interest rates. Check for fees, flexibility and early repayment charges.

Underestimating Additional Costs

Many buyers focus on the deposit and mortgage repayments but forget about additional costs like stamp duty, solicitor fees, valuation costs, and moving expenses.

How to Avoid It

Budget for all potential costs, including:

• • Stamp duty (if applicable)
  • Legal/conveyancing fees
  • Surveys and home insurance
  • Mortgage arrangement and booking fees
  • Have an emergency fund to cover any unexpected costs.

Submitting Incomplete or Incorrect Paperwork

Missing or incorrect documents can delay your mortgage approval or even lead to a declined application.

How to Avoid It

Be prepared with key documents, including:

• • Proof of income (payslips, tax returns if self-employed)
  • Bank statements (usually the last 3–6 months)
  • Proof of address and ID (utility bills, passport, driving licence)

Work with a mortgage advisor to ensure everything is in order before submission.

Not Considering Future Interest Rate Changes

If you opt for a variable-rate mortgage, your payments can fluctuate—sometimes significantly. Some buyers don’t consider how future rate changes could affect their affordability.

How to Avoid It

If you need stability, a fixed rate mortgage could be a better option.

If choosing a variable rate, calculate how much your payments could increase in a worst case scenario.

Keep an eye on economic trends. Interest rates can change based on inflation and Bank of England decision.

Applying for a mortgage can feel overwhelming, but with the right preparation and expert advice, you can avoid common pitfalls and secure the best deal for your situation.
