Get on the property ladder with the right mortgage.

One of the first questions every first-time buyer asks is how much they can actually borrow. Most UK lenders use an income multiple to calculate your maximum mortgage, typically offering between 4 and 4.5 times your annual gross salary. If you earn £30,000, that means you could borrow between £120,000 and £135,000. For joint applications where two incomes are combined, the borrowing capacity increases significantly, which is why buying with a partner or family member can open the door to properties that would be out of reach on a single salary alone.

However, the income multiple is only the starting point. Lenders also carry out a detailed affordability assessment that looks at your regular outgoings, existing debts, credit commitments, and essential living costs. If you have a car loan, credit card balances, or high childcare expenses, these will reduce the amount a lender is willing to offer. Student loan repayments are also factored into your monthly outgoings, though they do not appear as a debt on your credit file. Understanding how lenders view your full financial picture is essential before you start viewing properties, so you know exactly what is realistic.

This is where working with a mortgage broker gives you a genuine advantage. Different lenders have different affordability models, and some are considerably more generous than others for first-time buyers. A whole-of-market broker can identify which lenders will offer you the most competitive deal based on your specific income, deposit, and personal circumstances. Some specialist lenders will stretch to 5 or even 5.5 times income for applicants in certain professions or with strong financial profiles. Without a broker, you would never know these options existed, and you could end up borrowing less than you need or paying more than you should.

The UK government offers several schemes designed specifically to help first-time buyers get onto the property ladder, and understanding what is available to you could save thousands of pounds or make the difference between affording a home and being stuck renting. The First Homes scheme offers newly built properties to first-time buyers at a discount of at least 30% below market value, with the discount passed on to future buyers when you eventually sell. Eligibility is based on local connection and household income caps, typically £80,000 outside London and £90,000 within it. Shared ownership is another popular route, allowing you to buy a share of a property (usually between 25% and 75%) and pay rent on the remainder, with the option to staircase up to full ownership over time.

The Lifetime ISA remains one of the most valuable savings tools for first-time buyers. If you are between 18 and 39, you can save up to £4,000 per year and the government will add a 25% bonus on top, giving you up to £1,000 in free money each year towards your deposit. You can use a Lifetime ISA to buy a property worth up to £450,000. First-time buyers in England and Northern Ireland also benefit from stamp duty relief, paying no stamp duty on the first £425,000 of a property purchase and a reduced rate on the portion between £425,001 and £625,000. For many buyers, this means paying no stamp duty at all, saving up to £6,250 compared with what a home mover would pay.

Regional schemes also offer significant support. In Scotland, the First Home Fund has provided shared equity loans of up to £25,000 towards the purchase price, though availability varies by budget cycle. In Wales, the Help to Buy Wales shared equity scheme offers loans of up to 20% of the purchase price on new-build homes, interest-free for the first five years. While the original Help to Buy equity loan scheme in England closed to new applicants in 2023, its legacy means many new-build developments were specifically designed for first-time buyers and may still have favourable mortgage products attached. Your broker will know which schemes you qualify for and can help you navigate the application process for each one, ensuring you take advantage of every pound of support available.

Your deposit is the single biggest factor that determines both which mortgage deals you can access and what interest rate you will pay. The minimum deposit for most first-time buyer mortgages is 5% of the property price, which means a £200,000 home requires at least £10,000 upfront. With a 5% deposit, you would be borrowing at 95% loan-to-value (LTV), which means your mortgage covers 95% of the property's value. While 95% LTV deals have become widely available again, they tend to carry higher interest rates because the lender is taking on more risk. Even a modest increase in your deposit can make a meaningful difference to your monthly payments and the total cost of your mortgage over its lifetime.

The relationship between deposit size and interest rate is significant. Moving from a 95% LTV to a 90% LTV (a 10% deposit) typically reduces your interest rate noticeably, and the savings accelerate further at 85%, 80%, and 75% LTV thresholds. For example, on a £200,000 mortgage, the difference between a 95% LTV rate and an 85% LTV rate could save you over £100 per month. If you are close to one of these thresholds, it can be well worth finding ways to boost your deposit. Popular strategies include saving into a Lifetime ISA for the government bonus, cutting back on discretionary spending for six to twelve months, or asking family members whether they can help.

Gifted deposits from the Bank of Mum and Dad are increasingly common and are accepted by the vast majority of UK lenders. If a family member is willing to gift you money towards your deposit, the lender will require a signed gifted deposit letter confirming that the money is a gift and not a loan, and that the person giving it has no interest in the property. Some lenders will also ask to see bank statements from the person gifting the funds to verify the source. It is important to understand that a gifted deposit cannot come with any expectation of repayment, as lenders will treat it as a loan if they suspect that is the case. Your broker can advise on exactly what documentation is needed and which lenders are most straightforward about gifted deposits, so the process runs smoothly from the start.

Choosing the right type of mortgage is one of the most important decisions you will make as a first-time buyer, and the options can feel confusing at first. A fixed rate mortgage locks your interest rate for a set period, usually two or five years, meaning your monthly payments stay exactly the same regardless of what happens to the Bank of England base rate. This predictability makes fixed rates the most popular choice for first-time buyers, particularly those on tight budgets who need to know precisely what they will pay each month. Two-year fixes tend to have slightly lower initial rates but leave you renegotiating sooner, while five-year fixes offer longer stability and protection against rate rises, which many first-time buyers find reassuring during their early years of homeownership.

A tracker mortgage follows the Bank of England base rate plus a set margin, so your payments go up and down as interest rates change. Trackers can be cheaper than fixed rates when the base rate is stable or falling, but they carry the risk that your payments could increase if rates rise. Variable rate mortgages, including discounted variable rates and standard variable rates, work on a similar principle but are set by the lender rather than directly tracking the base rate. For first-time buyers who are comfortable with some uncertainty and have enough financial headroom to absorb potential increases, a tracker can offer savings. However, most advisers recommend the certainty of a fixed rate for your first mortgage, especially given that you are already adjusting to the costs of homeownership.

Offset mortgages are another option worth considering if you have savings. With an offset mortgage, your savings are held in an account linked to your mortgage, and you only pay interest on the difference between your mortgage balance and your savings balance. For example, if you have a £180,000 mortgage and £20,000 in savings, you would only pay interest on £160,000. You do not earn interest on the savings, but the tax-free benefit of reducing your mortgage interest can be more valuable, particularly for higher-rate taxpayers. When deciding how long to fix for, consider your plans for the next few years. If you might need to move within two to three years, a two-year fix avoids early repayment charges. If you plan to stay put for the foreseeable future, a five-year fix gives you security and peace of mind while you settle into your new home.
