The home buying timeline: from Agreement in Principle to getting the keys
Posted on 15/09/2026 by Kay Kowalewska
Buying a home is one of the biggest financial commitments you'll ever make. Whether you're a first-time buyer or moving to your next property, understanding the home buying process can help make the journey less stressful.
From securing an Agreement in Principle to collecting your keys on completion day, here's what you can expect.
Step 1: Speak to an independent mortgage adviser
Before you start viewing properties, your first step should be to speak with an independent mortgage adviser. This allows you to understand exactly how much you could borrow, what your monthly repayments may look like and, more importantly, what you can comfortably afford based on your income, outgoings and plans.
An adviser will assess your financial circumstances, explain the different mortgage products available and recommend the most suitable options for your needs. They can also compare mortgages from a wide range of lenders, helping you find a competitive deal rather than limiting you to a single bank's products.
Once you have established your budget, your adviser can arrange an Agreement in Principle (AIP). An AIP is an indication from a lender of how much they may be willing to lend, subject to a full application. Having an AIP in place before you begin house hunting shows estate agents and sellers that you are a serious buyer and can strengthen your position when making an offer.
This is also the ideal time to discuss protecting your mortgage and your family. While no one likes to think about unexpected events, having the right protection in place can provide valuable peace of mind.
Your adviser may recommend:
- Life insurance: helps repay your mortgage or provides a lump sum to your loved ones if you pass away during the policy term.
- Critical illness cover: pays a tax-free lump sum if you are diagnosed with a specified serious illness, helping you meet mortgage repayments or other financial commitments while you recover.
- Income protection: provides a regular monthly income if you are unable to work due to illness or injury, helping you continue paying your mortgage and household bills until you're able to return to work or the policy ends.
Protecting your income can be just as important as arranging your mortgage. By discussing these options from the outset, you can ensure your new home remains financially secure should the unexpected happen.
Step 2: Find your ideal property
Once your Agreement in Principle is in place, you can begin searching for your new home.
Take time to view several properties and consider factors such as location, transport links, local schools, future resale value and any renovation costs. Don't feel pressured into making a decision too quickly finding the right property is worth the wait.
Step 3: Make an offer
When you've found the right home, it's time to make an offer through the estate agent.
If your offer is accepted, the property is usually taken off the market, although it isn't legally binding at this stage. The buying process can still fall through until contracts have been exchanged, so it's important to move forward promptly with your mortgage application and legal work.
Step 4: Submit your mortgage application
Once your offer has been accepted, your mortgage adviser will submit your full mortgage application to the lender.
You'll normally need to provide documents such as:
- Proof of identity
- Proof of income
- Recent bank statements
- Evidence of your deposit
Your lender will then assess your application and arrange a valuation of the property.
Step 5: Property valuation and surveys
The lender's valuation confirms whether the property provides suitable security for the mortgage. However, this isn't the same as a survey.
Depending on the age and condition of the property, you may wish to arrange a HomeBuyer Report or a full Building Survey to identify any potential structural issues before committing to the purchase.
Step 6: Receive your mortgage offer
If your application is approved, the lender will issue your formal mortgage offer.
Your solicitor will receive a copy and begin preparing for the legal process, including reviewing contracts, carrying out property searches and raising any enquiries with the seller's solicitor.
This stage can take several weeks, depending on how quickly information is returned and whether there are any issues to resolve.
Step 7: Exchange contracts
Exchange of contracts is one of the most important milestones in the home buying process.
Once contracts have been exchanged, the purchase becomes legally binding. You'll normally pay your deposit at this stage, and a completion date will be agreed between both parties.
After exchange, neither the buyer nor the seller can withdraw without financial consequences.
Step 8: Completion day
Completion day is when the remaining funds are transferred to the seller, and ownership of the property officially changes hands.
Once your solicitor confirms completion has taken place, you can collect the keys from the estate agent and move into your new home.
Congratulations, you've completed your home purchase!
How long does the process take?
Every purchase is different, but the average home buying process in the UK typically takes between 8 and 16 weeks from having an offer accepted to completion.
Factors such as property chains, mortgage processing times, survey results and legal enquiries can all affect how quickly your purchase progresses.
Starting your mortgage application early and responding promptly to requests for documents can help avoid unnecessary delays.
