How Long Does a Mortgage Offer Last?

25th Aug 2020 (Last updated on 25th Nov 2020) 5 minute read

Once you have secured a mortgage, you are given a limited time for which the offer is valid to complete the property purchase. Usually, this is 3-6 months from the time the mortgage is offered, depending on the lender. If you are concerned your property purchase won’t be completed in time, you will need to contact your lender to request an extension. Otherwise, you will need to reapply for the mortgage.

Securing a mortgage offer is a crucial step in buying a property. With the average house price in the UK currently at £238,885, a mortgage is the only way many people can afford a home, especially considering the overall cost of buying a house.

Compare My Move has reviewed the latest and most relevant information on mortgages. We will provide you with everything you need to know about the length of mortgage offers and what to do if your mortgage offer expires.

This article will cover the following:
  1. What Happens Once a Mortgage is Approved?
  2. Can a Mortgage Offer Be Extended?
  3. Mortgage Offers for Off-Plan New-Build Homes
  4. Can a Mortgage Offer Be Withdrawn?
  5. What If I Have to Reapply for My Mortgage?
  6. Save on Your Property Purchase with Compare My Move

What Happens Once a Mortgage is Approved?

Once your mortgage has been approved, your lender will send both you and your conveyancer an official mortgage offer in writing. This will state how long the offer is valid for, usually 3-6 months. This allows for the length of time it takes to buy a house, including property surveys and the conveyancing process

The purchase must be completed within the time frame of the valid offer. If it surpasses the validation period, you will need to request a renewal on the offer, or in some cases, reapply. 

Lenders will understand that the house buying process is lengthy, complex and often has unexpected delays. However, keeping a constant stream of communication between you and your lender is vital, especially if you are concerned your mortgage offer may expire before you complete on the purchase.

A formal mortgage offer should not be confused with a Mortgage Agreement in Principle which is the lenders’ word that they can offer you a mortgage. An agreement in principle is normally valid for 90 days.

Can a Mortgage Offer Be Extended?

Lenders understand that each house purchase is different and there can be unexpected delays along the way. They may be willing to extend your mortgage offer based on the circumstances which require you to obtain an extension. For example, many lenders extended mortgage offers by up to three months during the UK-wide lockdown as a result of the Coronavirus pandemic.

However, a lender has no obligation to extend or re-offer your mortgage offer and they may ask to see recent bank statements and payslips. This is to ensure your credit score is still good and your circumstances haven’t changed. 

If you are concerned your house purchase won’t be completed within the time frame of the mortgage offer, contact your lender as soon as possible. The lender will require a few weeks notice if they are to consider extending your mortgage offer, so regular communication with them is vital.

How long the mortgage offer is extended for is at the discretion of the mortgage lender, but it could be over a month or more. It will also depend on your individual circumstances and the circumstances of the property sale. Lenders must ensure that mortgage candidates are risk-free and in a position to pay back the loan. 

Mortgage Offers for Off-Plan New-Build Homes

In some cases, a mortgage offer will expire or be due to expire before the completed construction of a new build property. Developers can overrun on their time scales or there can be delays in which can set back the planned completion of property development. 

With an off-plan property, buyers are often reserving properties before construction even begins. With most mortgage offers lasting in the region of 6 months, any delay in the building process may mean the mortgage offer could expire before the home is completed. 

According to the New Homes Review Annual Report 2019, only 64% of new-build homes were built on time. This, however, is an improvement from 2017 which saw just 59% of homes completed on time.

If you are buying a property off-plan and yet to be built, it may be worth working with a mortgage broker and looking into mortgages with longer offer periods or those better suited for new-build homes.

Can a Mortgage Offer Be Withdrawn?

Regardless of whether the mortgages expire or not, a mortgage offer can be withdrawn if the lender is made aware of any changes to your circumstances or any issues are raised with the property which makes either yourself or the property undesirable for a loan offer.

If the lender feels there is a risk, they are within their right to withdraw and refuse a loan. This is why it is strongly advised that you do not take on any other loans or large financial commitments until the purchase is completed. In the event your offer is withdrawn, you will need to re-apply for a mortgage.

What If I Have to Reapply for My Mortgage?

Reapplying for a mortgage can cost you both time and money, setting back your purchase even further. If your mortgage offer has expired, it is strongly advised that you reapply swiftly as there is no legal obligation for the lender to reoffer a mortgage.

If your circumstances have changed from the time the offer was first made, this will be taken into consideration as the lender will need to be sure you are still a good candidate for a mortgage. 

If your circumstances and credit score have changed for the better, potentially you could be in a position for a better mortgage offer than your original agreement. You could also look for a better offer elsewhere, or hire a mortgage broker to look into the best deals available.

Be aware if you are reapplying, this may mean paying for another property valuation. You may also face potential. You may also face additional conveyancing costs. You will need to undergo another credit check, so ensure that your financial affairs are in order before reapplying.
