Getting your mortgage offer can feel like the final hurdle in the home-buying process, but it is not an open-ended guarantee. Every mortgage offer comes with an expiry date and failing to complete your purchase within that timeframe can lead to delays, extra costs or the need to reapply.
Understanding when a mortgage offer expires, why lenders impose these time limits and what to do if your deadline is approaching is important for buyers navigating an already complex process. This article explains how long mortgage offers typically last, why they expire and what practical steps you can take to protect your deal.
How long does a mortgage offer usually last?
In most cases, a mortgage offer remains valid for three to six months, although the exact length varies between lenders. Not all lenders calculate the validity period in the same way. Some calculate the expiry date from the date of application, while others do it from the date on which the mortgage offer is issued. This distinction can shorten your effective window by several weeks, making it essential to read the offer document carefully, rather than relying on general assumptions.
Because a mortgage offer is specific to both the borrower and the property, the expiry date represents the lender’s comfort level with the information available about both at the time.
Why mortgage offers expire
Mortgage offers expire because they are based on a snapshot of financial and market information. Lenders need to manage risks, which can increase as time passes. Here are some key reasons why offers are subject to a time limit:
Your financial position can change
A mortgage offer is issued based on your income, employment status, credit profile and existing commitments at the time of application. Over several months, these factors can change. A new loan reduced income or change in employment can materially affect affordability from a mortgage lender’s perspective. Rather than leaving offers open, lenders impose expiry dates to ensure that the information used to assess your application remains current and reliable.
Property valuations become outdated
Mortgage offers also rely on a valuation of the property that you intend to buy. Housing markets move, sometimes quickly. If a valuation is several months old, it may no longer reflect the current market value of the property. For this reason, lenders limit how long they are prepared to rely on a valuation before reassessing their risk. If your purchase does not complete on time, the lender may require a new mortgage valuation before extending or reissuing your mortgage offer.
Market conditions evolve
Interest rates, lending criteria and regulatory requirements can all change over a period of a few months. A mortgage offer locks in terms based on prevailing conditions and lenders cannot commit indefinitely when the broader environment may shift. Expiry dates allow lenders to reassess offers in line with market realities and updated policies.
What happens if your mortgage offer expires?
If your mortgage offer expires before completion, you will not be able to draw down the loan on the original terms. You may need to reapply or request an extension, both of which can introduce uncertainty.
Depending on circumstances, this could result in:
- A reassessment of affordability
- A new property valuation
- Different interest rates or fees
- Delays to completion
In the worst-case scenario, the lender may withdraw the offer entirely, requiring the buyer to restart the mortgage process.
Can you extend a mortgage offer?
Lenders will consider extending a mortgage offer in some cases, but this is not automatic. Extensions are assessed on a case-by-case basis and depend on both the lender’s policies and whether your circumstances have changed.
A mortgage lender may agree to an extension if:
- Your financial position is unchanged
- The property valuation is still valid
- Lending criteria remain the same
Alternatively, an extension may still require some updated documents or a refreshed valuation. In some cases, fees may apply.
When should you act if your offer is close to expiry?
Timing is important. If your completion date looks uncertain, it is advisable to act at least three to four weeks before your mortgage offer expires. This allows time for discussions with your lender or broker without any last-minute pressures. Leaving it too late can limit your options and increase the risk of having to reapply for a mortgage with potentially less favourable terms.
Steps to take if your mortgage offer is nearing expiry
1. Contact your lender or broker early
The first step is to speak to your lender or mortgage adviser as soon as you identify a potential delay. They can confirm the exact expiry date and explain whether an extension is possible.
2. Avoid financial changes
During the period between offer and completion, stability matters. Avoid changing jobs, taking on new credit or making large purchases. Such changes can trigger reassessment and potentially jeopardise your current mortgage offer.
3. Keep the conveyancing process moving
Many offers expire due to delays in conveyancing, surveys or chains. Regular communication with your solicitor and the estate agent can help identify bottlenecks early and keep the transaction progressing.
4. Prepare for a possible revaluation
If your offer requires extension, the lender may request updated documents, such as ban statements, and a fresh valuation. Be prepared for the possibility that this could affect the loan-to-value ratio, particularly if market conditions have changed in the meantime.
Does the expiry period differ by transaction type?
The length of a mortgage offer can vary depending on whether you are purchasing a new-build property or an existing home. New-build purchases sometimes come with longer offer validity periods, reflecting longer construction timelines. However, these offers may include conditions requiring updated checks closer to completion. For standard purchases and remortgages, most mortgage offers fall within the three-to-six-month range.
Why reading your offer letter matters
Mortgage offer documents contain important information beyond interest rates and monthly payments. The expiry date, conditions for extension and circumstances under which an offer can be withdrawn are all usually set out in writing.
Assuming all lenders operate in the same way can lead to misunderstandings. Always confirm:
- The exact expiry date
- How the expiry is calculated
- Whether extensions are permitted
Conclusion
A mortgage offer is a vital step in the home-buying process, but it is not the end of the journey. Every mortgage offer comes with a defined expiry period designed to protect lenders against changing financial and property market conditions.
Understanding how long your mortgage offer lasts and what steps to take if delays arise can help you avoid any last-minute stress and potentially adverse financial consequences. Acting early, maintaining financial stability and staying in close contact with your solicitor and the estate agent are key to ensuring your purchase completes on time. In short, managing the mortgage offer timeline is just as important as securing the offer itself.
