21 Common Mortgage Questions Answered
Clear, practical answers to the questions UK homebuyers, homeowners and landlords commonly ask about mortgages, deposits, affordability, remortgaging and financial protection.
Arranging a mortgage can feel complicated, especially when lender criteria, interest rates and affordability calculations vary from one provider to another.
Whether you are purchasing your first property, moving home, investing in a buy-to-let property or reviewing your existing mortgage, getting the right advice can make the process easier.
The advisers at Gordon Blair Mortgage & Insurance Brokers can assess your circumstances, explain your options and help identify suitable products from a wide range of mortgage lenders.
How much can I borrow for a mortgage?
The amount you may be able to borrow depends on your income, regular expenditure, existing debts, credit history, deposit, employment status and the lender's affordability criteria.
Although income multiples can provide a rough indication, lenders usually complete a more detailed affordability assessment before making a decision.
How much deposit do I need to buy a home?
The deposit required will depend on the mortgage products available, the type of property and your individual circumstances. Some buyers may qualify for a low-deposit mortgage, while others may need to contribute more.
A larger deposit usually reduces the loan-to-value ratio and may give you access to a broader selection of mortgage deals.
First-time buyers can read more about the process on our first-time buyer mortgage page .
What credit score do I need for a mortgage?
There is no single credit score that guarantees mortgage approval. Credit-reference agencies use different scoring systems, while each lender applies its own lending criteria.
Lenders may review your payment history, credit utilisation, electoral-roll information, outstanding balances and any previous missed payments or defaults.
A less-than-perfect credit history does not always prevent you from securing a mortgage. It may, however, reduce the number of lenders or products available.
What is a mortgage Agreement in Principle?
An Agreement in Principle, sometimes called a Decision in Principle, is an indication of how much a lender may be prepared to lend based on the information available at that stage.
It can help you establish a property budget and demonstrate to estate agents that you have started reviewing your mortgage options. It is not a formal mortgage offer and remains subject to further underwriting, affordability checks and a suitable property valuation.
Should I choose a fixed or variable-rate mortgage?
A fixed-rate mortgage keeps the interest rate unchanged during an agreed initial period. This can provide certainty because your contractual monthly repayment will not change solely due to movements in general interest rates during that period.
A variable or tracker mortgage can move up or down according to the product's terms. This may provide greater flexibility in some cases, but repayments can also increase.
The appropriate option depends on your budget, plans, attitude to risk and the product fees or early repayment charges involved.

Mortgage timescales vary. The lender's workload, the complexity of the application, the property valuation and the speed at which supporting documents are provided can all affect the process.
Preparing your identification, income evidence, bank statements and deposit information in advance can help reduce avoidable delays.
Can I get a mortgage if I am self-employed?
Yes. Self-employed applicants can obtain mortgages, although lenders may assess income differently from employed applicants.
Depending on the lender and your business structure, you may need to provide tax calculations, tax-year overviews, company accounts, business bank statements or evidence from your accountant.
A broker can identify lenders whose criteria are better suited to sole traders, company directors, partners, contractors and other self-employed applicants.
What documents do I need for a mortgage?
Commonly requested documents include:
- Proof of identity and address
- Recent payslips or evidence of self-employed income
- Personal bank statements
- Details of loans, credit cards and other commitments
- Evidence showing the source of your deposit
- Property and estate-agent details
Requirements vary between lenders, so additional evidence may be requested during underwriting.
Can I remortgage before my current deal ends?
You can investigate remortgage options before your existing deal expires. Starting early can give you time to compare products and complete the application before moving onto your lender's follow-on rate.
However, completing a remortgage too soon could trigger an early repayment charge. Your adviser should compare the potential saving with all fees and penalties before recommending a change.
What fees are involved in arranging a mortgage?
Potential costs may include:
- Mortgage product or arrangement fees
- Property valuation fees
- Legal and conveyancing costs
- Survey fees
- Broker fees, where applicable
- Stamp Duty Land Tax, where payable
- Removal and property-related costs
A mortgage with a lower headline rate is not automatically the least expensive option. Product fees and total costs should be considered alongside the rate.
What does loan-to-value mean?
Loan-to-value, or LTV, compares the amount you wish to borrow with the property's value.
For example, if a property is valued at £300,000 and the mortgage is £240,000, the LTV is 80%.
Lenders group products into LTV bands. A lower LTV can sometimes provide access to a wider selection of rates, although eligibility will still depend on the full application.
Can I make mortgage overpayments?
Many mortgage products permit regular or lump-sum overpayments. Overpaying can reduce the outstanding balance and the amount of interest charged over the mortgage term.
Products may restrict the amount you can overpay without incurring an early repayment charge. Check your mortgage offer or contact the lender before making an additional payment.
What happens to my mortgage if interest rates rise?
If you are within a fixed-rate period, your interest rate will normally remain unchanged until that period ends, subject to the conditions of your mortgage.
Payments on variable and tracker products may increase when the relevant underlying rate changes. Borrowers approaching the end of a fixed deal should review their options in advance rather than waiting until the final month.
Should I use a mortgage broker or approach a bank directly?
A bank can normally discuss only its own mortgage range. A broker can assess products from a broader panel of lenders, subject to the scope of the service offered.
A mortgage broker can also help you understand lender criteria, prepare documentation, submit the application and communicate with the lender during underwriting.

A mortgage is usually a long-term financial commitment. Depending on your needs, it may be appropriate to consider life insurance, critical illness cover, income protection or other forms of financial protection.
The right policy will depend on your income, family, employment benefits, savings, debts and existing cover.

Can I buy my first home with a small deposit?
Low-deposit mortgage products may be available, but the minimum deposit and eligibility criteria vary between lenders and can change over time.
Buyers should also budget for legal fees, surveys, moving costs and any applicable property taxes rather than using all available savings for the deposit.
Our first-time buyer advisers can explain the options currently available for your circumstances.
What happens after my offer on a property is accepted?
The usual process includes:
- Confirming your mortgage product and submitting the application
- Providing supporting documents to the lender
- The lender arranging a property valuation
- Your solicitor completing searches and legal checks
- The lender issuing a formal mortgage offer
- Exchanging contracts
- Completing the purchase and receiving the keys
The exact order and timing can vary, particularly in Scotland or where a property chain is involved.
What should I do if my mortgage application was declined?
Avoid immediately submitting several new applications. Each lender has different criteria, and repeated applications may result in additional credit searches.
A broker can help identify the likely reason for the decline, review your credit history and assess whether another lender may be more appropriate.
Approval can never be guaranteed, but understanding the cause of a decline can help you choose a more suitable next step.
Can I move my existing mortgage to a new property?
Some mortgage products are portable, meaning you may be able to transfer the existing product to a new property.
Porting is not automatic. The lender will usually reassess affordability, your circumstances and the new property. If you need additional borrowing, that portion may be arranged on a different product and rate.
When should I speak to a mortgage adviser?
It is sensible to seek advice before making an offer. An early review can help you understand your likely budget, deposit requirements, monthly costs and potential lender options.
Existing homeowners should also begin reviewing their options several months before a current mortgage deal expires.
