The average age of a first-time buyer in the UK now sits at 33.9 years, and that number has been climbing steadily for decades. What that figure tells me, after years of watching this market, is that the path to homeownership has become a longer, more deliberate process than it used to be — and the factors that determine whether you get a mortgage have shifted just as much as the age has. If you’re trying to buy your first home right now, understanding what lenders actually look at is the difference between getting an offer and getting nowhere.
Nearly 390,000 first-time buyers completed purchases in 2025 — an 18% increase on the year before — and they now account for 54% of all mortgage-backed property purchases. That’s a huge chunk of the market. But the numbers also reveal a tougher reality: the average deposit nationally sits between £60,000 and £64,000, and in London it exceeds £120,000. Over half of first-time buyer households now rely on dual incomes just to qualify for a mortgage. The days of walking into a bank with a single salary and a small deposit are largely gone. Here’s what you actually need to know.
I’ve spent a lot of time looking at how these figures play out in real life, and one thing is clear: the mortgage approval process isn’t a mystery, but it does reward preparation. If you understand the payment options available to you and how lenders assess risk, you can position yourself far better than most buyers ever do. A good first step is to get professional guidance — speaking with a financial advisor can help you map out your affordability before you even start viewing properties.
What Lenders Actually Mean by Affordability
Most people assume a mortgage decision comes down to how much you earn. That’s part of it, but it’s not the whole picture. Lenders use something called an affordability assessment, and it’s more detailed than a simple salary multiple. They look at your income, your outgoings, your credit history, and the property’s value — all at once. The national house price-to-earnings ratio for first-time buyers is currently 4.7 times annual gross income, which is actually below the 20-year average for the first time since 2020. That sounds encouraging, but it masks huge regional differences. In Scotland the ratio is 2.9 times; in London it’s far higher.
What I tend to notice is that buyers focus on the deposit number and forget about the stress test. Lenders check whether you could still afford the mortgage if interest rates rose by 3% or more. That’s why someone earning £50,000 with a perfect credit score might be offered less than someone earning £40,000 with no debt and a larger deposit. The deposit isn’t just about the lump sum — it’s about proving you’re a lower risk. If you’re unsure where you stand, it’s worth understanding the difference between leasehold and freehold before you commit, because the property type can affect mortgage availability too.
Why the Deposit Barrier Hits Harder Than You Think
The average first-time buyer deposit nationally is £60,000 to £64,000. That’s roughly 20–25% of the purchase price. In London, it’s over £120,000. Those numbers are daunting, but the real story is in how long it takes to get there. For someone earning the median salary of £34,000 and saving 15% of their gross income, a 10% deposit on a £226,000 home would take about 4.4 years. That’s assuming no rent, no emergencies, and no life getting in the way. In practice, a London renter paying £1,400 a month in rent would need more than 15 years to save a 10% deposit while covering living expenses.
That’s why the “Bank of Mum and Dad” has become so significant. An estimated 30–40% of first-time buyers now receive some form of family financial assistance, with the average gifted deposit contribution sitting around £25,000 to £30,000. Family-assisted buyers enter the market 3 to 5 years earlier than those saving independently. If you don’t have that support, the timeline stretches considerably. The tips for senior citizens buying a home might not apply directly to you, but the principle of planning ahead absolutely does — especially if you’re saving without family help.
One thing I’d say from watching this pattern repeat: don’t underestimate the value of a Lifetime ISA. It gives you a 25% government bonus on savings toward a first home, up to a maximum bonus of £1,000 per year. That’s essentially free money toward your deposit, and it’s one of the few schemes still available after Help to Buy closed. If you’re saving for a deposit, that should be your first port of call.
Where First-Time Buyers Trip Up on Mortgage Applications
I’ve seen the same mistakes come up again and again. They’re not about bad credit or low income — they’re about things people simply didn’t know mattered. Here are the most common ones, backed by what the data actually shows.
Ignoring the Impact of Small Debts on Borrowing Capacity
A credit card with a £2,000 balance might not feel like a big deal. But lenders treat it as a monthly commitment, and that reduces how much they’re willing to lend. Even a small personal loan or a buy-now-pay-later agreement can knock thousands off your maximum mortgage. The fix is straightforward: pay down as much debt as possible in the six months before you apply. Don’t just make minimum payments — clear the balances. Lenders look at your credit utilisation ratio, and keeping it below 30% makes a noticeable difference.
Applying Without Checking Your Credit File First
Around 1 in 4 credit reports contain errors, according to industry estimates. A wrong address, a misreported late payment, or even a duplicate entry can lower your score. If you apply for a mortgage with an error on your file, you might be rejected — and that rejection stays on your record. Check your credit file with all three major agencies (Experian, Equifax, and TransUnion) at least three months before you apply. Dispute any errors immediately. It’s boring admin, but it’s the kind of thing that separates a yes from a no.
Overlooking the Stamp Duty Threshold Change
Since April 2025, the stamp duty nil-rate threshold for first-time buyers is £300,000, down from £425,000. That means if you’re buying a home for £310,000, you’ll pay stamp duty on the £10,000 above the threshold — not on the whole amount. But if you’re buying in London or the South East, where average prices are well above £300,000, the tax bill can be significant. Factor that into your deposit calculation. A property lawyer can walk you through exactly what you’ll owe based on your purchase price and location.
Assuming a Higher Salary Automatically Means a Bigger Mortgage
Lenders don’t just look at your income — they look at your outgoings. Someone earning £60,000 with a car loan, a personal loan, and high rent might be offered less than someone earning £40,000 with no debt and low living costs. The affordability assessment models your monthly spending, and if you’re spending a large chunk of your income on existing commitments, the lender assumes you can’t take on more. The fix is to reduce your committed spending in the months before you apply. Cancel unused subscriptions, pay off loans early if you can, and avoid taking on new credit.

How to Position Yourself for Mortgage Approval
Getting a mortgage isn’t about luck. It’s about knowing what lenders want and giving it to them. Here’s the practical sequence I’d follow if I were starting from scratch today.
Build a Clean Credit Profile Six Months Before Applying
Lenders run a full credit check, and they look at your history over the last six years. But the six months before your application carry the most weight. Register on the electoral roll at your current address — it’s one of the simplest ways to boost your score. Pay all bills on time, every time. Avoid applying for new credit cards or loans during this period, because each application leaves a footprint. If you’re buying with a partner, both of your credit files need to be clean. One person’s poor history can drag down the joint application.
Maximise Your Deposit Using Every Available Scheme
The Mortgage Guarantee Scheme is still running, supporting 95% loan-to-value mortgages on homes up to £600,000. That means you can buy with a 5% deposit, though the interest rate will be higher than if you had 10% or 20%. The Lifetime ISA gives you a 25% bonus on savings up to £4,000 per year, which is effectively free money toward your deposit. If you’re saving with a partner, you can both open one. The key is to start early — the bonus is paid monthly, so the longer you save, the more you get. Avoid using a Help to Buy ISA if you already have a Lifetime ISA, because you can only use one bonus scheme for a first home purchase.
Get Your Paperwork Organised Before You View Properties
Lenders will ask for three months of bank statements, three months of payslips, a P60, proof of deposit source, and proof of identity. If you’re self-employed, they’ll want two to three years of accounts. Having all of this ready before you make an offer speeds up the process enormously. I’d also recommend getting a Decision in Principle (also called an Agreement in Principle) from a lender before you start viewing. It’s not a guarantee, but it tells you how much you can borrow and shows estate agents you’re serious. You can get one online in about 15 minutes, and it doesn’t affect your credit score if you use a soft search.
Consider the Long-Term Costs Beyond the Mortgage
Your monthly mortgage payment is only part of the picture. You’ll also need to budget for buildings insurance, life insurance (many lenders require it), council tax, utility bills, and maintenance. A good rule of thumb is to add 10–15% to your expected monthly housing costs to cover these extras. If you’re buying an older property, a water leak detector is a small investment that can save you thousands in undetected damage — and it’s the kind of practical preparation that shows you’re thinking ahead. Also, check the council tax band for the property before you make an offer, because it can add £100–£300 to your monthly outgoings depending on the band.
The Emerging Shift: How Remote Work Is Changing Affordability
One trend I’m watching closely is how remote and hybrid working is reshaping where first-time buyers can afford to buy. The data shows that housing affordability improved in 70% of UK local authority areas over the past year. That’s partly because buyers are moving to cheaper regions while keeping London or South East salaries. If you can work remotely, you’re not tied to expensive urban markets. Areas like Inverclyde in Scotland, where the average FTB price is around £100,000, or Burnley in the North West at roughly £95,000, become realistic options. The trade-off is that you need to be sure your job is genuinely remote — not just hybrid with occasional office days — because lenders will check your commuting costs as part of the affordability assessment.
