The more you can save for your deposit, the less you'll need to borrow — and the better the mortgage rates you'll be offered. Here's a clear breakdown of what different deposit sizes mean for you:
Many buyers turn to online calculators to get an initial idea of affordability — but these tools are often inaccurate, particularly for first-time buyers whose situations can be more nuanced (variable income, multiple income sources, unusual employment types, etc.).Our advisers will assess your actual borrowing capacity based on your specific income, outgoings, credit profile, and the criteria of individual lenders. This gives you a real, reliable figure — not a ballpark estimate.
Important: The monthly repayment figure you'll pay depends on three things: how much you borrow, the interest rate offered, and the length of your mortgage term. With rates higher now than in recent years, it's essential to get an accurate repayment figure before you start viewing properties — so you can set a realistic budget.
How Does Mortgage Term Affect Monthly Payments?
The average mortgage term is 25 years, but many lenders now extend this to 35 or even 40 years, provided you'll still be below retirement age at the end of the term. A longer term means lower monthly payments — but you'll pay more in total interest over time. Your adviser will help you find the right balance.
A mortgage is not the only expense when buying your first home. Before you begin viewing properties, make sure you've planned for these one-off upfront costs:
Ongoing Costs Once You Move In
Beyond the mortgage payment itself, homeownership comes with regular ongoing costs you should plan for from day one:
Our advisers always walk through a full budget planner with you before any application is submitted — making sure you're comfortable with both the mortgage payment and the wider financial picture of homeownership.
Most lenders require a minimum deposit of 5% of the property's purchase price. A 10% deposit will improve your chances and typically unlock better rates. If you can save 15% or more, you will have access to the most competitive deals on the market.
Most lenders will offer between 4 and 4.5 times your annual income. Some specialist lenders will go higher, up to 5 or even 5.5 times income, depending on your profession, income level, and credit profile. A mortgage broker can identify which lenders are likely to offer you the most.
Beyond your deposit, budget for Stamp Duty (though first time buyers are exempt on the first £425,000), solicitor or conveyancing fees, a mortgage arrangement fee if applicable, a survey, and buildings insurance. These costs can add several thousand pounds to your purchase.
Yes. A 35 or 40 year term will lower your monthly repayments compared to a 25 year term. The trade-off is that you pay more interest overall. Many first time buyers opt for a longer term to keep payments affordable, with the intention of overpaying or reducing the term when their income grows.
Yes, most lenders accept gifted deposits, typically from close family members such as parents or grandparents. The donor will usually need to sign a gifted deposit letter confirming the money is a gift and not a loan. Your solicitor and lender will both need to be made aware.
