Your mortgage offer is through. Good news – but do not start measuring for the sofa just yet. What happens after mortgage offer is the part of the buying process where loose ends become legally binding commitments, and where avoidable mistakes can still derail a move.
The lender has agreed, in principle and subject to its stated conditions, to lend you the money. Your solicitor still needs to complete the legal work, everyone in the chain needs to be ready, and you need to keep your finances steady. This is the stage for calm action, not expensive celebrations on credit.
What Happens After a Mortgage Offer?
Once your formal mortgage offer arrives, your conveyancer or solicitor receives a copy too. They check the terms, confirm the mortgage amount and repayment basis, and make sure the property meets the lender’s requirements.
Read the offer yourself as well. Check the property address, loan amount, mortgage term, interest rate, product fee, monthly payment and any special conditions. A mistake in a name, address or purchase price needs sorting immediately. Do not assume someone else will spot it.
Most mortgage offers are valid for a limited period, often around three to six months. The exact expiry date is printed on the offer. That date matters because a slow chain, delayed new-build completion or unresolved legal issue can mean asking the lender for an extension or, in some cases, submitting a new application.
An offer is a major milestone, but it is not a contract. You are not legally committed to buy until contracts have been exchanged.
The Legal Work Keeps Moving
Your solicitor now takes centre stage. They will carry out or review the searches, raise enquiries with the seller’s solicitor, check the title to the property and review the contract pack. This is not paperwork for paperwork’s sake. It is how you find out whether there are restrictions, planned local developments, access issues, leasehold costs or other problems that could affect the home and its value.
If you are buying a leasehold flat, expect more questions. Your solicitor needs information about the lease length, service charges, ground rent, building insurance, planned major works and the management company. A cheap-looking flat can become an expensive mistake if the paperwork reveals a large bill around the corner.
The lender’s valuation is also worth understanding. It is mainly for the lender, not a detailed inspection for you. Even if the valuation was satisfactory, you may still want a separate survey, particularly for an older property, a non-standard build or a home with visible signs of damp, movement or alterations. Finding a problem before exchange gives you choices. Finding it after completion gives you a bill.
You Will Agree an Exchange and Completion Date
While the legal checks continue, your solicitor, estate agent and the rest of the chain work towards dates for exchange and completion. Exchange is the point at which signed contracts are swapped and the deal becomes legally binding. Completion is when the money is sent, ownership transfers and you collect the keys.
These dates are often the source of frustration because your purchase may depend on several other sales completing at the same time. One missing document, one delayed mortgage offer or one buyer changing plans can hold up everyone else.
Before exchange, you will normally need to send your deposit to your solicitor. This is commonly 10% of the purchase price, although a lower amount may be agreed, especially where your deposit is smaller or there is a chain. Your solicitor will tell you exactly where to send it. Always verify bank details by telephone using a trusted number – conveyancing fraud is real, and criminals target buyers when large sums are moving.
Once contracts are exchanged, pulling out can be costly. If you are the buyer and fail to complete, you could lose your deposit and face further claims. That is why rushing to exchange before the facts, funds and dates are genuinely in place is a terrible idea.
Do Not Give the Lender a Reason to Recheck You
Here is the trap many buyers do not see coming: a mortgage offer does not always mean the lender has stopped looking at your circumstances. Some lenders carry out final checks before completion. They may check your credit file, employment, account conduct or source of deposit again, particularly if there is a long gap before completion.
Until the keys are in your hand, treat your financial position as frozen. That means no new finance, no missed payments and no unexplained money movements. Avoid changing jobs unless you have discussed it with your adviser and lender. Even a sensible change, such as moving to a better-paid role, can require reassessment if you are still in probation or your income structure changes.
Keep these four rules in place until completion:
- Do not apply for a credit card, car finance, buy-now-pay-later account or new mobile contract.
- Do not reduce your deposit by buying furniture, appliances or a holiday before completion.
- Do not move money between accounts without keeping a clear record of where it came from.
- Do not make major changes to your employment, hours or self-employed income without getting advice first.
This is not lenders being difficult for the sake of it. They approved a particular application based on particular evidence. Change the evidence and they may need to change the decision.
Arrange Insurance at the Right Time
If you are buying a house, buildings insurance usually needs to start from exchange of contracts, not completion. From exchange, you are committed to buy and may be responsible for the property if something goes wrong. Your solicitor will confirm the position for your transaction.
For a leasehold flat, buildings cover is often arranged through the freeholder or managing agent and funded through service charges. Check rather than guess. Your lender will want to know the building is properly insured.
This is also a sensible moment to consider life insurance, critical illness cover and income protection. They are not simply add-ons to tick off. The right protection can stop a family being forced to sell if illness, death or loss of income hits. The wrong policy, or a policy bought without checking exclusions and affordability, is just another monthly cost. Get advice based on your circumstances.
What Can Delay Completion After an Offer?
The biggest delays are rarely dramatic. More often, they are ordinary details that take longer than expected: a missing management pack, a boundary query, a gifted deposit that needs evidence, a survey issue, an unresolved title defect or a buyer elsewhere in the chain waiting for their own mortgage.
New-build purchases have their own pressure point. Developers may set a tight exchange deadline, while the final build date can still move. Your mortgage offer might need extending if construction is delayed. Do not let a sales deadline push you into exchanging before you understand the contract, incentives, deposit arrangements and long-stop completion date.
If a problem appears, do not panic and do not bury your head in the sand. Ask what it means, what evidence is needed and whether it affects value, mortgageability or your willingness to proceed. Sometimes the answer is a simple document. Sometimes it is a price renegotiation. Occasionally, walking away is the financially smart decision.
Completion Day: When the Home Becomes Yours
On completion day, your solicitor requests the mortgage funds from the lender and transfers the balance to the seller’s solicitor. Once the seller’s solicitor confirms receipt, the estate agent can release the keys.
Completion is usually not a precise morning appointment. Funds can move through the banking system at different times, and chains can create knock-on delays. Keep removals flexible where possible, make sure your solicitor has cleared funds for any balance due, and wait for confirmation before turning up at the agent’s office.
After completion, your solicitor deals with Stamp Duty Land Tax where applicable and registers your ownership and the lender’s charge with HM Land Registry. This can take time, especially where the Land Registry has a backlog, but it does not stop you moving in.
A mortgage offer is proof that you have cleared a huge hurdle. Now protect it. Keep your money stable, respond quickly to your solicitor’s requests and do not let excitement persuade you to skip checks that could cost you years of regret.
