Questions to ask your mortgage broker

Why these questions matter

Buying a home is a major financial decision, and the mortgage process can feel complex. A good mortgage broker should be able to explain the steps clearly, set expectations on timescales and costs, and help you understand which mortgage options genuinely fit your circumstances.

Use the questions below to check that you’re working with someone who communicates well and can guide you confidently from early planning through to application and offer.

1) What are your fees, and when will they be due?

Mortgage brokers may charge in different ways. Ask for a clear breakdown of:

• Whether there’s an advice fee, arrangement fee, or both
• When the fee is payable (for example, before or after an application)
• What happens if you decide not to proceed
• Whether the fee changes if your case becomes more complex

A transparent answer helps you budget properly and avoid surprises later.

2) Are you authorised to give mortgage advice, and what qualifications do you hold?

Mortgage advice is regulated. It’s reasonable to ask how the adviser is authorised and what professional standards they work to.

You may also want to ask:

• Who will be handling your case day to day
• How the adviser stays up to date with lender and product changes

3) Do you work with a wide range of lenders, or a limited panel?

Different brokers have different access to lenders and products. Ask:

• Whether they can search across the whole of market or only certain lenders
• How they decide which lenders to approach for your situation
• Whether they can explain why particular lenders are more suitable than others

The goal is to understand how your options are being selected.

4) How do you handle situations that aren’t straightforward?

Even if you feel your application is “simple”, it’s worth asking how the broker supports cases such as:

• Irregular income or commission
• Self-employed or mixed income
• Credit history issues
• Multiple debts or existing commitments
• Complex property scenarios (for example, unusual purchase structures)

A broker should be able to describe their approach and how they manage risk and documentation.

5) Based on my details, what mortgage amount might I be able to borrow?

Borrowing capacity depends on more than just income. Ask what factors will be considered, such as:

• Affordability assessment and monthly outgoings
• Deposit size and any deposit source requirements
• Credit profile and existing borrowing
• Employment type and stability

You can also ask whether they will provide an initial estimate and then refine it once they have full information.

6) What deposit will I need, and how does it affect the options available?

Deposit size can influence both eligibility and the range of products you may be offered. Ask:

• What deposit you’d ideally target for the best range of options
• Whether a smaller deposit changes the approach
• How gifted deposits or other deposit sources are handled

A clear explanation helps you plan your timeline and savings strategy.

7) What type of mortgage is likely to suit me, and why?

There are different mortgage types and structures. Ask your broker to explain the options in plain terms, including:

• Fixed-rate and variable-rate choices
• Term length considerations
• Repayment vs interest-only (where applicable)
• Any trade-offs between monthly payment and overall cost

A suitable recommendation should be based on your priorities—such as budgeting certainty, flexibility, or longer-term plans.

8) What documents will you need from me, and how should I prepare them?

Mortgage applications rely on evidence. Ask for a checklist of what they typically require, and how to avoid delays.

Common areas to cover include:

• Proof of identity and address
• Income evidence (payslips, accounts, or other documentation)
• Bank statements
• Details of existing finances and commitments
• Deposit proof
• Any information related to the property purchase

You can also ask how long it usually takes to gather everything and whether there are any “common mistakes” to avoid.

9) What are the likely costs involved in the wider purchase process?

A mortgage isn’t the only cost when buying a home. Ask your broker to help you think through the main expenses, such as:

• Valuation or survey-related costs
• Solicitor and conveyancing fees
• Building insurance (where required)
• Stamp Duty Land Tax (if applicable)
• Mortgage-related fees

Even if exact figures vary, understanding the categories helps you plan realistically.

10) What does the timeline look like, from application to offer?

Timelines can vary depending on lender processes and the complexity of the case. Ask:

• What the typical sequence of steps is
• How long each stage can take
• What might cause delays
• How they keep you updated during underwriting and processing

Good brokers set expectations early so you know what to watch for.

11) How will you communicate with me during the process?

Buying a home involves multiple parties. Ask how your broker will manage communication, for example:

• How often you’ll receive updates
• Whether they coordinate with lenders and other professionals
• How you’ll be notified if additional information is required

Clear communication reduces stress and helps keep momentum.

12) What happens if my circumstances change?

Life doesn’t always stay still during a purchase. Ask how they would handle changes such as:

• A change in income
• A change in employment status
• A late change to deposit timing
• Additional debts or credit applications

A broker should explain how changes can affect affordability and lender decisions.

13) Will you review the mortgage offer before I commit?

Before you proceed, it’s helpful to understand what checks will be carried out. Ask whether they will:

• Review the mortgage offer details with you
• Highlight key terms and any conditions
• Explain what you need to do next to keep the process on track

14) What support is available after the mortgage is arranged?

While the broker’s role often focuses on getting the mortgage in place, it’s still worth asking about longer-term support, such as:

• How to approach future changes
• Options if you want to remortgage later
• Whether they can help you understand product switches or refinancing considerations

A quick “pre-meeting” checklist

To get the most from your first conversation, consider having:

• Your target purchase price and estimated deposit
• Basic income and employment details
• An overview of existing monthly commitments
• Any known credit or affordability concerns (if applicable)
• A list of questions you want answered

Summary

The best mortgage brokers don’t just find products—they explain the process, clarify costs and timelines, and help you understand why a mortgage is suitable for your circumstances. Using the questions above can help you assess whether your broker is the right fit before you move forward with an application.
