For many first-time buyers, the mortgage process can feel complex and unfamiliar. With new terminology, multiple decisions to make and little prior experience to rely on, it is easy to make mistakes that could delay your purchase or lead to a mortgage that is not well suited to your circumstances.
However, many of these common mistakes are avoidable with the right guidance and professional support. A mortgage adviser helps simplify the process, explains your options in clear, straightforward terms and ensures your application is structured correctly from the outset, so you can make confident decisions that align with both your current situation and future goals.
In this article, we explain how a mortgage adviser can help first-time buyers avoid costly pitfalls, understand what you can realistically afford and secure a mortgage that suits your needs. Whether you are just beginning your home-buying journey or preparing to apply, this guide is designed to help you move forward feeling informed, supported and confident at every stage.
1. Maxing out borrowing without considering what is realistically affordable.
A common mistake first-time buyers make is focusing on how much a lender may be willing to offer, rather than what feels affordable and comfortable month to month. While it can be tempting to borrow the maximum amount available, this can lead to unnecessary financial pressure once mortgage repayments begin.
How lenders determine your affordability
When you apply for a mortgage, lenders carry out affordability checks to assess how much you can borrow and what you can reasonably afford to repay. These assessments consider factors such as your income, regular outgoings, existing credit commitments, employment details and deposit size. While these checks help reduce the risk of overborrowing, they do not always reflect how a mortgage will feel alongside your lifestyle and everyday spending.
Importantly, you are not required to borrow the maximum amount you are offered, and doing so may not be the most suitable option for your long-term financial wellbeing.
What to consider when deciding how much you should borrow
Understanding how much you spend on essentials and lifestyle choices, such as food, transport, childcare, hobbies and social activities, helps ensure your mortgage fits around your life rather than restricting it.
It is also essential to consider the full cost of homeownership as mortgage repayments are only one element of monthly expenses, alongside costs such as council tax, utilities, protection policies and other household costs.
These costs should be factored in when considering how much you want to borrow, to ensure your finances remain sustainable after you have moved into your new home and do not restrict your disposable income.
How our advisers can help
Working alongside one of our mortgage advisers will help ensure you select a product that is appropriate for your current and future financial situation. Our advisers will work to gain a complete holistic understanding of your financial circumstances and can advise on what may be the most appropriate and sustainable option for your long-term financial health.
Additionally, consider leaving room in your budget for the unexpected. Keeping a small financial buffer for emergencies, rising bills or future interest rate changes can provide flexibility and help reduce financial stress over the long term.
As part of the process our advisers also conduct financial assessments which take into account your future financial goals and any potential impacts on maintaining your mortgage in the long term.
2. Assuming the cheapest rate is always the best deal.
Although a low interest rate may look appealing, it might not always result in the lowest overall cost. Associated fees, incentives, term tie-ins, portability and flexibility are key factors that should be considered when determining whether a mortgage is suitable for your personal circumstances.
In some cases, the benefits of these factors may outweigh the significance of a lower rate. For example, a mortgage with the lowest interest rate may come with higher product arrangement fees which counteract the long-term savings.
Alternatively, if you are planning to grow your family within the next couple years, securing a mortgage with the flexibility to port it mid-term may be more suitable than securing a mortgage with a lower rate but limited flexibility.
How our advisers can help
It is important to look at the overall product and not just the headline rate when establishing which product may be right for you.
Our mortgage advisers can clearly explain the options available to you, offering clarity and guidance when your options may be confusing or overwhelming. They will also ensure you understand the terms, exclusions and flexibility included with each product, which can help you determine which product is best suited for your long-term goals.
3. Overlooking additional costs.
It is common for first-time buyers to underestimate the wider costs involved in purchasing a property, with many first-time buyers focusing solely on their deposit.
However, it is important to consider budgeting for the additional costs listed below:
| Cost to budget for | Purpose of the cost | Typical price range |
| Mortgage arrangement fees | Covers the lender for setting up your mortgage. | £0 to over £2,000 (residential properties). |
| Solicitor fees | Cover the legal work involved in transferring property ownership into your name. | Typically, £1,500 plus VAT. |
| Valuation fees | Confirms the properties market value before approving the mortgage. | £350 to £1,500 (some lenders may offer free valuations). |
| Property searches | Checks for local issues, such as planning restrictions, flood risks, or environmental concerns. | £250 to £450. |
| Land registry fees | Paid to officially register the property in your name. | £20 to £1,000. |
Additionally, as a first-time buyer you will likely not be required to pay any Stamp Duty, provided you are within the following criteria:
| Property Price | Stamp Duty Relief Charges |
| Up to £300,000 | 0% |
| £300,001 to £500,000 | 5% |
However, if you purchase a property over £500,000, your Stamp Duty Relief will be lost, and you will be subject to standard Stamp Duty charges.
You can check how much stamp duty you may be liable to pay using the Cooper Associates Group Stamp Duty Calculator.
How our advisers can help
These costs can add up quickly, making early advice from a mortgage adviser essential for ensuring you are prepared and avoiding potential financial strain once the process begins.
Our advisers offer fee-free, no obligation consultations, where they can advise you throughout the entire mortgage process and are able to answer any questions you may have regarding the charges that may affect you. This ensures you are not only financially prepared but feel reassured when setting savings goals and embarking on your mortgage journey. We can also talk through the possible benefits or implications of reducing or increasing your deposit to allow the availability of additional funds for other available costs.
4. Applying for a mortgage before checking their credit history.
Applying for a mortgage without checking your credit score first can sometimes uncover surprises, such as historic missed payments, incorrect information on your credit report or a lower score than expected, potentially making you appear higher risk to lenders and leading to unfavourable terms or higher rates.
For this reason, it is recommended that you review your credit score at least six months prior to applying for a mortgage. This allows time for you to maintain and improve your score, for example by correcting any errors, maintaining consistent on-time payments, and reducing outstanding balances (e.g. credit cards or loans). Demonstrating stable and responsible credit behaviour over several months can strengthen your financial profile and improve lender confidence, leading to more favourable terms and potentially increasing your chances of approval.
How our advisers can help
A mortgage adviser can support this process by reviewing your credit position early, identifying potential concerns and advising on practical steps to improve your profile before applying, helping to reduce the risk of delays or declines. Additionally, if you have low or adverse credit history this does not automatically result in rejection. Our advisers have access to whole-of-market products and can access specialist lenders who focus on helping individuals with adverse credit history.
However, it is important to maintain and improve your credit score throughout your lifetime to ensure your financial profile remains healthy and does impact your borrowing capabilities down the line.
5. Not reviewing mortgage terms and conditions carefully.
Many first-time buyers focus on the interest rate and monthly repayments but overlook the finer details of a mortgage, which can have a significant impact down the line.
Key features such as the type of mortgage you select (e.g. fixed-rate, tracker, discounted) and Early Repayment Charges (ERCs) which may apply if you repay or change your mortgage before a fixed or discounted period ends, can potentially result in unexpected costs. Additionally, overpayment limits also vary between lenders and can restrict how much you are able to pay off early without incurring charges, which may affect future financial flexibility.
Portability is another important factor that is often missed. This determines whether you can transfer your mortgage to a new property if you move home before your current deal ends. Not all mortgages are portable, and conditions can apply, which may limit your options.
Reviewing these terms carefully helps ensure your mortgage not only suits your current situation but also remains appropriate if your circumstances change.
How our advisers can help
A mortgage adviser will explain these features clearly, helping you choose a product that balances affordability, flexibility and long-term suitability.
During the initial consultation, we will take the time to understand your personal circumstances and goals for the future, ensuring that the mortgage product we recommend will be tailored to your current and future needs.
