How to Buy Your First Home in the UK (The Whole Process, In Order)

Buying your first home in the UK follows the same nine steps every time: build your deposit, get mortgage-ready, get an agreement in principle, find the right property, make an offer, get your mortgage approved, do the legal work, exchange contracts, and complete. The whole thing typically takes three to six months from offer to keys — but most of the delays (and most of the expensive mistakes) happen because nobody tells first-time buyers what order to do things in.

That's what this guide fixes. Here's every step, in the right order, in plain English.

Step 1: Work out what you can actually afford

Not what a lender will give you — what keeps you comfortable. Lenders will typically let you borrow around 4 to 4.5 times your annual income, but the number that matters is your monthly payment sitting alongside your real life: bills, food, travel, and still having a life.

Start with your deposit. Most first-time buyers put down between 5% and 15% of the property price. A bigger deposit usually unlocks better mortgage rates — the jump from 5% to 10% makes a real difference to what you'll pay every month.

Then add the costs nobody mentions: legal fees, surveys, property tax, moving costs. Budget several thousand pounds on top of your deposit — our True Cost calculator itemises the lot for your exact price and region.

Step 2: Build the deposit (and use the free money)

If you're saving for a first home and you're under 40, look at a Lifetime ISA — the government adds a 25% bonus to what you save, up to set annual limits. There are conditions (property price caps, how long the account must be open), so read them before relying on it.

Step 3: Get mortgage-ready — before you apply

This is the step almost everyone does too late. Lenders judge you on your last three to six months of financial behaviour, so the time to tidy up is before you apply, not the week you find a house you love. Register on the electoral roll, check your credit report, avoid new credit and gambling transactions on your statements, and get your paperwork lined up. We've written a full guide to getting mortgage-ready — and our free Mortgage Readiness Score shows you where you stand in about a minute.

Step 4: Get an agreement in principle

An agreement in principle (AIP) is a lender's indication of what they'd likely lend you, based on basic checks. It's not a guarantee — but estate agents take you far more seriously with one, and in a competitive market it's often the difference between your offer being considered and being ignored. A mortgage broker can arrange one, usually within a day or two.

Step 5: Find the right property (not just a nice one)

Viewings are where first-time buyers get emotional and sellers get paid. Go in with a checklist: damp, cracks, the boiler's age, the roof, what the neighbours' places look like, how long it's been on the market, and why the seller is moving. View more than once, at different times of day. And remember the estate agent works for the seller — friendly is not the same as on your side.

Step 6: Make your offer — and negotiate

The asking price is a marketing number, not a valuation. What the property is worth is what similar homes nearby have actually sold for. Offer based on evidence, not on fear of losing it. We've broken down exactly how to negotiate the price and how to get your offer accepted — read both before you pick up the phone.

Step 7: Mortgage application, survey and legal work

Once your offer's accepted, three things run in parallel:

1. Full mortgage application — the lender values the property and underwrites you properly.
2. Your survey — not the lender's valuation, yours. A Level 2 Homebuyer survey suits most conventional homes; a Level 3 Building survey suits older or unusual ones. Skipping this to save a few hundred pounds is how people buy five-figure problems.
3. Conveyancing — your solicitor checks the legal title, runs searches, and raises enquiries. This is usually the slowest part. Chase weekly, politely.

Step 8: Exchange contracts

Exchange is the moment it becomes legally binding — you pay your deposit across, and if either side pulls out after this, there are real financial consequences. Get buildings insurance in place from exchange, not completion; you're responsible for the property from this point in most cases.

Step 9: Completion — keys day

The money moves, the seller's solicitor confirms, and the agent releases the keys. That's it. You're in.

The mistakes that cost first-time buyers the most

• Falling in love with a house before checking what it's genuinely worth
• Applying for a mortgage with a messy three months of bank statements
• Skipping the survey
• Only budgeting for the deposit and getting ambushed by everything else
• Trusting that everyone in the chain is "on it" instead of chasing

We've covered all of these — and five more — in the first-time buyer mistakes guide.

The honest bit

You can do all of this on your own. Thousands of people muddle through every month. But muddling through the biggest purchase of your life, against professionals who do this every day, is exactly how first-time buyers lose thousands without ever knowing it happened.
