The Step-by-Step Mortgage Process for First-Time Buyers Explained
Buying your first home. It sounds exciting, doesn’t it? That mix of pride, panic, and possibility all rolled into one. You’ve probably imagined collecting the keys, painting walls, choosing furniture. But before you even get to that point, there’s the bit that makes most people’s heads spin – the mortgage process.
It’s not just a case of walking into a bank, filling out a form, and walking out with a mortgage offer. There’s a sequence to it – some steps you’ll breeze through, others that’ll test your patience. But once you understand the flow, it all starts to make sense. So let’s strip away the jargon and walk through it, start to finish, as if we were chatting over a coffee.
Step 1: Work out what you can afford
Before you even think about browsing properties, you need to know your numbers.
Mortgage lenders will typically allow you to borrow around 4 to 4.5 times your annual income. If you’re buying with a partner, it’s based on your combined earnings.
Let’s say you earn £35,000 and your partner earns £25,000. That’s a total of £60,000. Multiply by 4.5 and you’re looking at a potential mortgage of £270,000.
Now, that doesn’t automatically mean you should borrow that much. You’ll need to factor in your deposit, bills, council tax, food, travel, and all those “hidden” costs of owning a home (repairs, insurance, the occasional boiler disaster).
| Income | Approx. Mortgage (4.5x) | 5% Deposit | Total Buying Power |
|---|---|---|---|
| £30,000 | £135,000 | £7,100 | £142,100 |
| £50,000 | £225,000 | £11,800 | £236,800 |
| £70,000 | £315,000 | £16,600 | £331,600 |
Figures are for example purposes only.
The more accurate way to find out what you can afford is through a mortgage in principle (we’ll get to that in a moment). But right now, you just need a ballpark figure – something to narrow your search and stop you scrolling homes you can’t afford.
Step 2: Start saving your deposit
Ah, the deposit. The single biggest barrier for most first-time buyers.
You’ll usually need at least 5% of the property price. That means a £10,000 deposit for a £200,000 home. If you can stretch to 10% or more, even better – it usually unlocks lower interest rates and smaller monthly repayments.
Government schemes like the Lifetime ISA (LISA) can help speed things up. You can save up to £4,000 per year and get a 25% government bonus (that’s £1,000 free money annually).

Step 3: Check your credit score
Before any lender even glances at your application, they’ll check your credit file. This shows how reliable you’ve been at repaying money in the past – credit cards, loans, phone contracts, that sort of thing.
You can check your credit score for free using sites like ClearScore, Experian, or TransUnion. If it’s low, don’t panic. Even small tweaks can improve it:
- Pay bills on time (every time).
- Get on the electoral roll.
- Don’t max out credit cards.
- Avoid too many “hard” credit applications at once.
It’s worth sorting this early. A strong score can make the difference between being accepted or rejected – or paying hundreds less each month.
Step 4: Get a Mortgage in Principle (AIP or DIP)
This is your “passport” to house-hunting.
A Mortgage in Principle (sometimes called an Agreement in Principle or Decision in Principle) is a statement from a lender confirming how much they might be willing to lend you. It’s based on your income, spending, and credit history.
You can usually get one online in minutes. Estate agents love them – it proves you’re a serious buyer, not just browsing for fun.
It’s not a guarantee, though. The final mortgage offer only comes after the lender has checked all your documents and the property itself. But it’s a solid step forward.
Step 5: Start viewing homes
Now for the fun part.
With your budget and AIP in hand, you can start viewing homes that actually fit your price range. It’s worth being realistic here – the UK property market can be brutal. That “perfect” house might already have ten offers on it by the time you book a viewing.
A few tips:
- Take photos and notes. After five viewings, they’ll all blur together.
- Ask questions. How old is the boiler? When was the roof last replaced?
- Think long-term. Can you grow into the space or will you outgrow it in a few years?
And don’t forget: an offer is just an offer. The property isn’t yours until contracts are exchanged.
Step 6: Make an offer
When you’ve found “the one”, it’s time to make your move.
You’ll usually make an offer through the estate agent. There’s no fixed formula, but you can often go slightly below asking price – especially if the property’s been on the market for a while.
If your offer is accepted, the agent will mark the property as “sold subject to contract” (SSTC). Then things get serious.
Step 7: Apply for your mortgage
Now comes the paperwork marathon.
Once your offer is accepted, you’ll formally apply for the mortgage. The lender will need:
- Proof of ID (passport or driving licence)
- Proof of income (payslips, P60, or tax returns if self-employed)
- Bank statements (usually 3–6 months)
- Details of your outgoings
They’ll also carry out a property valuation to make sure the house is worth what you’ve agreed to pay. You can choose a more detailed homebuyer’s report or full building survey if you want extra reassurance – particularly for older properties.
| Survey Type | Typical Cost | Best For |
|---|---|---|
| Basic Valuation | £250–£400 | New builds, low-risk homes |
| Homebuyer’s Report | £400–£700 | Most standard homes |
| Full Structural Survey | £700–£1,000+ | Older or unusual buildings |
It can take anywhere from two to six weeks to get your mortgage offer, depending on how complex your application is.
Step 8: Instruct a solicitor or conveyancer
This is the legal bit – and where your patience will be tested.
A conveyancer (or solicitor) handles the legal transfer of ownership from seller to buyer. They’ll:
- Check the title deeds.
- Conduct property searches (planning permissions, flood risks, etc.).
- Draft and exchange contracts.
- Transfer your deposit and complete the purchase.
They’ll also liaise with your lender to ensure the mortgage funds are released on time.
It’s not glamorous work, but it’s essential. Expect to pay £800–£1,500 depending on complexity and location.
Step 9: Receive your mortgage offer
Once the lender’s finished all their checks, they’ll issue a formal mortgage offer. This is the document that confirms:
- The amount they’re lending you
- The term (usually 25–35 years)
- The interest rate and type (fixed, tracker, etc.)
- Any conditions you need to meet
Review it carefully. Once you accept it, you’re legally bound to those terms. If you’re unsure about any clause, ask your solicitor to explain.
Step 10: Exchange contracts
This is the moment it becomes legally binding.
You and the seller sign contracts prepared by your solicitors, and you’ll transfer your deposit (usually 5–10%) to your solicitor’s client account. Once the contracts are exchanged, you can’t back out without losing that deposit.
At this point, you’ll also agree a completion date – the day you’ll officially get the keys. Usually, it’s one to two weeks after exchange, but it can vary.
Step 11: Completion day
Congratulations – you’ve made it.
On the morning of completion, your lender transfers the mortgage funds to your solicitor, who passes them to the seller’s solicitor. Once the seller confirms receipt, the estate agent hands over the keys.
That’s the moment you officially become a homeowner. (You’ll probably cry. Everyone does.)
Step 12: Move in and tie up loose ends
You’ll have a thousand little jobs to do in those first few days:
- Notify your council and utilities.
- Set up broadband and insurance.
- Change your address on the electoral roll and bank accounts.
But also, take a moment to enjoy it. You’ve just done something huge.
Common questions first-time buyers ask
How long does the mortgage process take from start to finish?
Typically, around 8–12 weeks from offer to completion. It can be quicker if everything runs smoothly – or longer if there are delays with searches or paperwork.
Can my mortgage be declined after offer?
It’s rare, but it can happen if your financial situation changes (e.g. you lose your job or take out new credit). Try to keep things stable between application and completion.
What if my valuation comes back lower than my offer?
This is called a down valuation. You can either renegotiate the price with the seller, increase your deposit, or switch to a smaller mortgage.
Do I need a solicitor and a mortgage adviser?
Yes. A solicitor deals with the legal side, while an adviser helps find and arrange your mortgage. They’re completely different roles – and both essential.

Final thoughts
If you’re a first-time buyer, the process can feel like an obstacle course – full of acronyms, waiting, and nail-biting decisions. But every single step has a purpose. Each form, check, and signature moves you closer to owning that front door key.
My advice? Stay patient, stay organised, and don’t be afraid to ask questions. Buying your first home is a massive milestone – it’s normal to feel daunted. But once you’re unpacking boxes and ordering your first takeaway on the living room floor, all the stress fades away.
It’s a lot, yes. But it’s worth it.
