How Much Could I Borrow for a Mortgage?

Before offering a mortgage, lenders assess whether repayments are sustainable for you over the long term. As a mortgage is secured against your home, it’s important to borrow within your means.

Mortgage providers will usually check:

  • Income – your salary and any regular additional income
  • Joint applications – combined income and credit history
  • Deposit size – most buyers will need at least 5%
  • Existing commitments – including credit cards, car finance, and other repayments
  • Spending habits – regular outgoings such as bills, childcare, and subscriptions
  • Credit score – how you’ve managed borrowing in the past may influence rates

What mortgage is right for me?

The right mortgage for you will depend on several factors, including your plans for the property, whether you’re a first-time buyer, remortgaging, or investing, and where you are in your buying journey.

Lenders offer a range of mortgage types and deals to suit different financial situations, deposit sizes, and long-term goals. Understanding your options can help you compare rates and choose a mortgage that aligns with your needs.

Types of Mortgages

Not all mortgages are the same, and choosing the right one can have a big impact on your finances. Understanding the main types of mortgages can help you compare mortgages effectively and select a deal that fits your goals, budget, and long-term plans. Knowing the differences between mortgage types also makes it easier to find competitive home loan rates and understand how repayments may change over time.
Mortgage Type Advantages Disadvantages
Fixed-rate Mortgage Monthly payments stay the same, making budgeting easier. Protects you if interest rates rise. May have higher initial rates than variable options. Less flexibility if you want to switch early.
Variable-rate Mortgage Flexibility to benefit if interest rates fall. Often lower initial rates than fixed mortgages. Monthly payments can go up if rates rise. Repayments are less predictable.
Tracker Mortgage Follows the Bank of England base rate, so you benefit directly if rates drop. Transparent and easy to track. Repayments rise if the base rate increases. Can be risky if interest rates fluctuate significantly.
Offset Mortgage Links savings to mortgage balance, reducing interest charged. Can lower the total cost of borrowing. Requires savings to be effective. May have higher fees or slightly higher interest rates than standard mortgages.
Interest-only Mortgage Lower monthly payments since you pay only the interest. Can free up cash flow in the short term. The full loan amount is due at the end of the term. Requires a clear repayment plan. Riskier for long-term affordability.
