Buying a home is exciting, but the mortgage process can seem confusing, especially if it’s your first time.
Understanding the key steps can make the journey much smoother — and help you feel confident every step of the way.
Here’s a simple breakdown of how the mortgage process works, from start to finish.
Step 1: Work Out Your Budget
Before you start viewing properties, it’s important to know how much you can afford to borrow — and comfortably repay.
- Look at your income, expenses, and any existing debts.
- Use online mortgage calculators or speak to a mortgage adviser to get an early estimate.
- Remember to factor in additional costs like deposits, solicitor fees, and moving expenses.
Step 2: Get a Mortgage Agreement in Principle (AIP)
A Mortgage Agreement in Principle (AIP) — sometimes called a Decision in Principle — is a statement from a lender saying they would, “in principle,” be willing to lend you a certain amount based on basic checks.
- It gives you a clear budget.
- It shows estate agents and sellers you are a serious buyer.
Getting an AIP doesn’t guarantee you’ll be offered a mortgage later, but it’s a strong first step.
Step 3: Find a Property and Make an Offer
Now the fun begins: house hunting!
Once you find a property you love:
- Make an offer through the estate agent.
- If your offer is accepted, the property will usually be marked as “Sold Subject to Contract” (SSTC).
At this stage, you’ll need to move quickly to secure your mortgage.
Step 4: Apply for a Mortgage
With an accepted offer, it’s time to submit a full mortgage application.
You’ll typically need to provide:
- Proof of income (payslips, accounts if self-employed)
- Bank statements
- ID and address verification
- Details about the property
A mortgage adviser can help you choose the best lender and deal for your situation.
Step 5: Mortgage Valuation and Underwriting
The lender will now:
- Arrange a mortgage valuation to check the property’s worth (this ensures it’s suitable security for the loan).
- Conduct underwriting — a detailed check of your finances, the property, and the documentation you provided.
They want to be sure you can afford the mortgage and that the property is good value.
Step 6: Receive a Mortgage Offer
If everything checks out, the lender will issue a formal mortgage offer.
This is the final confirmation that they agree to lend you the money.
- Review the offer carefully (your solicitor or adviser will help with this).
- Make sure you understand the terms before accepting.
Step 7: Exchange Contracts
At this point, your solicitor will:
- Finalise legal checks (known as conveyancing)
- Agree on a completion date with the seller
- Arrange for you to sign the contract
When you exchange contracts, you legally commit to buying the property and usually pay the deposit (commonly 5–10%).
Step 8: Completion
On completion day, the mortgage funds are transferred to the seller, and you officially become the new owner of the property.
- You collect the keys.
- You can now move into your new home!
Congratulations — you’re a homeowner!
