Buying a home is a major financial commitment, and arranging a mortgage can sometimes feel as complicated as finding the property itself. With different lenders, interest rates, mortgage types, affordability assessments and application requirements to consider, many homebuyers seek professional support to help them understand their options.
This is where mortgage services can provide useful guidance. Depending on the provider, these services may help buyers understand their borrowing position, compare suitable mortgage products, prepare an application and progress towards completion.
However, mortgage services vary, and buyers should understand what support is actually being offered before choosing an adviser or broker. This guide explains what mortgage support can involve and addresses some common misconceptions.
What Are Mortgage Services?
Mortgage services generally refer to professional support provided to people looking to arrange a mortgage or remortgage.
A mortgage adviser or broker may assess your circumstances, discuss your requirements and identify mortgage products that could be suitable. Some advisers may have access to a wide range of lenders, while others may work with a particular lender or panel.
Depending on the service, support can include:
- Assessing your borrowing requirements
- Reviewing income and expenditure
- Explaining mortgage types
- Comparing available products
- Discussing interest rates and fees
- Helping with mortgage applications
- Communicating with lenders
- Supporting the application through to completion
The precise service depends on the provider, so it is important to understand the scope of the advice before proceeding.
Mortgage Myth 1: Mortgage Advisers Only Help First-Time Buyers
Mortgage advice can be useful for many different types of borrowers.
First-time buyers may particularly benefit from guidance because they are unfamiliar with mortgage terminology and the buying process. However, existing homeowners may also seek advice when moving home, refinancing or reviewing their current mortgage.
Other circumstances where mortgage advice may be useful include:
- Moving to a larger or smaller property
- Buying an investment property
- Reviewing a mortgage when a fixed-rate period ends
- Borrowing with a smaller deposit
- Buying a property with another person
- Assessing borrowing options after a change in circumstances
Every borrower’s situation is different, so the appropriate level of support will depend on individual circumstances.
Mortgage Myth 2: A Mortgage Adviser Guarantees You the Best Rate
No adviser can guarantee that a particular mortgage will be the cheapest or most suitable option for every borrower.
Mortgage rates and product availability can change, while lenders apply their own eligibility and affordability criteria.
An adviser can explain available options and recommend products based on your circumstances, where they provide regulated mortgage advice. However, the lender ultimately decides whether to approve an application and on what terms.
When comparing mortgage products, look beyond the headline interest rate. Consider product fees, early repayment charges, mortgage term and other costs.
Mortgage Myth 3: Mortgage Services Are Only About Finding an Interest Rate
A mortgage involves considerably more than the headline rate.
A mortgage adviser may consider your overall financial position, including:
- Income
- Regular expenditure
- Existing debts
- Deposit
- Credit history
- Employment circumstances
- Property value
- Loan-to-value ratio
- Mortgage term
These factors can influence the types of mortgages you may be eligible for.
Understanding affordability is particularly important. A lender may be willing to offer a certain amount, but that does not necessarily mean borrowing the maximum available is financially comfortable for you.
What Types of Mortgage Can Advisers Explain?
One benefit of professional mortgage support is having someone explain how different mortgage products work.
Fixed-Rate Mortgages
A fixed-rate mortgage keeps the interest rate at an agreed level for a specified period. This can provide greater certainty over monthly payments during the fixed period.
Tracker Mortgages
A tracker mortgage typically follows a specified reference rate, often the Bank of England Bank Rate, plus or minus an agreed margin.
Payments can therefore change if the relevant rate changes.
Variable-Rate Mortgages
Other variable-rate products can change according to the lender’s terms.
Repayment Mortgages
With a repayment mortgage, monthly payments generally cover both interest and part of the capital borrowed, subject to the mortgage terms.
Interest-Only Mortgages
With an interest-only mortgage, monthly payments generally cover the interest rather than repaying the capital. These products have specific eligibility requirements and require borrowers to have an appropriate strategy for repaying the capital.
A mortgage adviser can explain the differences, but buyers should consider whether a particular product fits their long-term financial circumstances.
Mortgage Myth 4: You Can Apply for a Mortgage Without Preparing Your Finances
Preparation can make the process more straightforward.
Before applying, review your income, regular spending, existing credit commitments and available deposit.
Lenders may request documentation such as:
- Proof of identity
- Proof of income
- Bank statements
- Payslips
- Tax documents for self-employed applicants
- Details of existing financial commitments
Having these documents available can help reduce delays during the application.
It is also sensible to avoid taking on unnecessary new credit commitments immediately before applying for a mortgage, as lenders assess affordability and financial circumstances as part of their decision-making process.
Mortgage Myth 5: An Agreement in Principle Means Your Mortgage Is Approved
An agreement in principle is not the same as a formal mortgage offer.
An agreement in principle, sometimes called a decision in principle, provides an indication of how much a lender may be prepared to lend based on information available at that stage.
A full mortgage application involves more detailed checks. The lender may assess your documentation, financial circumstances and the property itself before issuing a formal mortgage offer.
Buyers should therefore avoid treating an agreement in principle as a guarantee that the mortgage will be approved.
What Support Can You Expect During the Application?
The level of support varies between mortgage advisers.
A typical service may involve helping you identify potentially suitable products, completing application paperwork and communicating with the lender.
Some advisers may also help monitor the progress of the application and respond to requests for additional information.
This can be particularly useful for buyers who are unfamiliar with mortgage terminology or who have a more complicated financial situation.
However, you should always ask the adviser what support they provide after an application has been submitted.
Mortgage Myth 6: Mortgage Advice Is Always Free
Not necessarily.
Some mortgage advisers charge a fee, some receive commission from lenders, and some may use a combination of charging structures.
Before proceeding, ask how the adviser is paid and whether you will have to pay a fee.
You should also understand whether the adviser provides advice from a broad range of lenders or only from a limited panel.
This information can help you understand the scope and potential cost of the service.
What Should Homebuyers Ask a Mortgage Adviser?
Before choosing a mortgage adviser, consider asking:
- Are you regulated to provide mortgage advice?
- How many lenders can you access?
- How are you paid?
- Will I pay an advice or arrangement fee?
- What types of mortgages do you advise on?
- What information will you need from me?
- How long does the application process typically take?
- What support will you provide after submitting the application?
- What happens if my application is declined?
Clear answers can help you decide whether the service is appropriate for your circumstances.
How Does Mortgage Advice Fit Into the Home-Buying Process?
Mortgage advice is only one part of buying a property.
You will also need to consider your deposit, property search, conveyancing, surveys, insurance and other costs associated with purchasing a home.
Ideally, establish your potential borrowing position before making an offer. Knowing your budget can help you focus your property search on homes that are realistically affordable.
However, avoid assuming that your maximum borrowing amount should automatically become your property budget. Leave room in your finances for household bills, maintenance, emergencies and changes in circumstances.
Final Thoughts
Arranging a mortgage can be one of the most important financial decisions involved in buying a home. Professional mortgage services can help explain different products, assess potential borrowing options and provide support during the application process.
However, mortgage advice is not a guarantee of approval or the lowest possible rate. Buyers should understand how an adviser operates, what lenders they can access and how their service is paid for.
Whether you are a first-time buyer, moving home or considering remortgaging, taking time to understand your options can help you make a more informed decision.
Before committing to a mortgage, consider the interest rate, fees, repayment structure, term, early repayment conditions and overall affordability. Where appropriate, seek advice from a suitably qualified and regulated mortgage professional who can assess your individual circumstances.
