Buying your first apartment in the UK is one of the biggest financial decisions you’ll ever make, and the numbers can feel daunting. Recent data shows that first-time buyers now need an average deposit of around 15–20% of the property price, which on a typical £250,000 flat means saving £37,500 to £50,000 before you even start looking. That figure alone explains why so many people feel stuck, but it also points to something important: the path to ownership is clearer than it seems once you know which levers to pull.
I’ve been covering the UK property market for years, and the question I hear most often is some version of “where do I even start?” The answer isn’t a single step — it’s a sequence of decisions that stack on top of each other. Get the first few right, and everything else gets easier. Here’s what you actually need to know.
Before you view a single flat, you need a Mortgage in Principle (MIP) — a lender’s conditional offer showing how much they’d lend you. Estate agents and sellers take you far more seriously with one in hand, and it stops you falling in love with a flat you can’t afford. A good whole-of-market broker can help you get one quickly, often within 24 hours, and many charge nothing upfront.
What a Lifetime ISA actually does for you
The Lifetime ISA is the single most powerful savings tool most first-time buyers never use. You can put in up to £4,000 each year, and the government adds 25% — that’s a guaranteed £1,000 bonus annually. Over five years, a couple maxing their LISAs would save £40,000 and receive £10,000 in government bonuses. That’s not a tax break or a discount — it’s cash added to your savings.
What I’d tell anyone starting out: open a LISA today, even if you can only put in £100. The clock starts ticking at age 40, and every year you don’t use it is a year of free money you’re leaving on the table. Just be crystal clear on the penalty — that 25% charge on unauthorised withdrawals means you shouldn’t put money in unless you’re confident you’ll use it for a home or retirement.
Why the true cost of buying catches most people out
The deposit is the headline number, but it’s not the only number that matters. Most first-time buyers I’ve spoken to underestimate the additional costs by a significant margin. According to detailed breakdowns of buying costs, you should budget at least £5,000 on top of your deposit for a standard purchase — and that’s a conservative estimate if you’re buying an older flat that needs a full building survey.
Here’s a realistic scenario: you find a one-bedroom apartment in Manchester for £180,000. Your 10% deposit is £18,000. But you also need £2,000 for a solicitor, £600 for a homebuyer report, £500 for a mortgage broker fee, £800 for removals, and £3,000 for basic furniture and appliances. That’s £7,000 in additional costs — nearly 40% of your deposit amount. If you’ve only saved the deposit, you’re stuck.
What I notice is that people who plan for these costs from the start have a much smoother experience. They’re not scrambling for extra cash two weeks before exchange. My advice: open a separate savings pot labelled “buying costs” and aim for at least £5,000 before you start viewing properties.
Where first-time buyers go wrong — and how to avoid it
After watching dozens of first-time purchases go through (and a few fall apart), I’ve noticed three patterns that cause the most trouble. Each one is avoidable with the right preparation.
Skipping the survey to save money
A basic mortgage valuation is not a survey. It’s the lender’s check that the property is worth what you’re paying — nothing more. A proper homebuyer report (£400–£1,000) or a full building survey (£600–£1,500 for older properties) can uncover structural issues, damp, roof problems, or wiring faults that would cost you thousands later. I’ve seen buyers skip this on a Victorian conversion flat and discover £8,000 of dry rot six months in. The survey would have cost £700. That’s a mistake you only make once.
Not getting a Mortgage in Principle before viewing
Estate agents and sellers treat buyers with an MIP as serious. Without one, you’re at the back of the queue. Worse, you might waste weeks viewing flats you can’t actually afford. An MIP takes 24 hours to get, involves a soft credit check (no impact on your score), and lasts 60–90 days. Get one before you book your first viewing. A good apartment hunting checklist will remind you of this and a dozen other steps you don’t want to forget.
Underestimating how long the process takes
From offer to completion, the average purchase takes 3–4 months in England and Wales. Delays happen — searches take longer than expected, chains collapse, solicitors go quiet. If you’ve given notice on your rental or set a hard moving date, you’re adding pressure to an already stressful process. Plan for 4 months minimum, and keep your rental flexibility until contracts are exchanged.
What I’d do differently if I were starting over: get the MIP and the survey sorted before I even made an offer. Those two things alone prevent the most common delays and disappointments. And if you’re buying an older flat, pay for the full building survey — it’s the best £1,000 you’ll spend.

Here’s the sequence I’d follow if I were buying my first apartment today. Each step builds on the last, and skipping one makes the next harder.
Step 1: Open a Lifetime ISA and start saving
If you’re under 40 and don’t have a LISA yet, open one this week. You can put in up to £4,000 per tax year and the government adds 25% — that’s free money. Both partners in a couple can open one, giving you a combined bonus potential of £2,000 per year. Over five years, that’s £10,000 in bonuses on £40,000 saved. The property price cap is £450,000, which covers most first-time apartment purchases outside central London. Just remember the 25% penalty if you withdraw for anything other than a first home or retirement — don’t save money you might need for emergencies.
Step 2: Get a Mortgage in Principle
This is your proof of affordability. A lender checks your income, outgoings, and credit history, then gives you a conditional offer showing how much they’d lend you. It’s usually a soft credit search, so it won’t affect your credit score. Take it to estate agents when you book viewings — it shows you’re a serious buyer. Most MIPs last 60–90 days, so time it right. If you’re not sure which lender to approach, a whole-of-market broker can help you compare options and often gets you a better rate than going direct.
Step 3: Research government schemes that apply to you
Several schemes are currently available, and one might save you thousands. Shared Ownership lets you buy a 25–75% share of a property and pay rent on the rest. First Homes offers 30–50% discounts on new-build properties for key workers and local buyers. The Mortgage Guarantee Scheme supports 5% deposit mortgages. Eligibility varies by location, income, and property type, so check the latest details on gov.uk before you start viewing. A comparison of apartment vs house buying can also help you decide which type of property suits your situation best.
Step 4: Budget for every cost — not just the deposit
Create a spreadsheet with two pots: your deposit fund and your buying costs fund. Aim for at least £5,000 in the costs pot. Include solicitor fees (£1,500–£3,000), a homebuyer survey (£400–£1,000), removals (£300–£2,000), and initial furnishing (£2,000–£10,000). If you’re buying an older flat, budget for a full building survey (£600–£1,500). Don’t forget buildings and contents insurance — your lender will require it before exchange, and it typically costs £200–£500 per year. A carbon monoxide alarm is a small but essential safety item for any flat, especially those with gas heating or a boiler in a cupboard.
Step 5: Move quickly once your offer is accepted
In England and Wales, the period between offer and exchange is vulnerable to gazumping — where the seller accepts a higher offer from someone else. Protect yourself by moving fast: instruct your solicitor immediately, book the survey within a week, and aim to exchange contracts within 8–10 weeks. Building a good relationship with the seller and estate agent also helps. If you’re buying in Scotland, the system is different — offers are typically made through a sealed bid process, and once accepted, the deal is legally binding much sooner.
