What is a Mortgage Valuation?

Buying your first home? You'll likely encounter a mortgage valuation during your mortgage application. Many first-time buyers confuse it with a Home Survey, but a mortgage valuation is not considered a Homebuyer's Survey.

Although you (the buyer) pay for it, this valuation is commissioned and conducted solely for the lender to confirm the property's value for their risk assessment. Therefore, you are unlikely to receive a copy of the valuation.

A mortgage valuation doesn't always mean a surveyor attended the property. These are known as desktop valuations and use online data to provide a valuation without a physical inspection.

We always recommend that you order a survey for yourself, completely separate from your mortgage lender, because it could save you from potentially making a huge mistake. If you do not get a home survey, you leave yourself open to missed defects costing you far more money down the line than the price of an inspection.


Is a Mortgage Valuation the same as a survey​?

No. While both involve a professional property assessment, they serve distinct purposes and offer different levels of detail. A mortgage valuation is primarily for the lender's benefit, while a survey is for the buyer.

The lender needs to confirm that the offered price reflects the property's fair market value. This ensures that if the lender needs to repossess the property, they can recoup their investment by selling it on the open market.

Surveyors may undervalue a property if they believe the offered price doesn't align with recent comparable property sales within the last six months, or if there's a defect affecting the property's value. However, it does not provide a detailed defect report. That's where a home survey comes in: we stress to our clients that they should commission a Level 2 or Level 3 HomeBuyer's survey.

At what stage is a Mortgage Valuation done?

A mortgage valuation is done during the mortgage application process, typically after your offer has been accepted and before the lender approves your mortgage.

It is the middle stage of the 3-stage mortgage process and is conducted by a Royal Institute of Chartered Surveyors (RICS) valuer instructed by your mortgage lender.

How long does a Mortgage Valuation take?

A mortgage valuation is often a relatively quick process, unlike a full detailed structural survey which can take several hours. It's sometimes conducted within minutes via a desktop valuation, or within an hour or so during a physical visit.

Desktop valuations use available data and therefore can miss issues that would be picked up on a physical inspection. For example, if the property has recent signs of pest infestation, this wouldn't be flagged in a desktop valuation.


Mortgage lenders advise you to get your own defect survey

The terms and conditions accompanying your lender's valuation report might state:

"We have carried out a valuation of the property, which is for lending purposes only. We use physical inspections or automated valuations to obtain a property valuation."

We strongly recommend that you obtain an independent property survey to satisfy yourself of the property's condition and value."

Home Survey

Full visual inspection of all accessible elements of the property, with a detailed report of findings.

Home Survey

Comprehensive report provided directly to the buyer.

Potential defects flagged in a Mortgage Valuation


Subsidence

If flagged in a valuation or a Level 2/3 Home Survey:

  • Subsidence can cause potential structural issues due to ground movement. It can manifest as cracks in walls, uneven floors, or leaning structures.
  • If flagged in a Mortgage Valuation or survey, you'll need a structural engineer or chartered building surveyor to come out and assess the cause and severity of the issue.
  • Subsidence can significantly impact your property's value so it cannot be missed or forgotten about.
  • It will not suffice to have a Building Survey (Level 3) or a HomeBuyer Report (Level 2) as a RICS surveyor cannot provide this service; you'd need a subsidence survey.

Damp

If flagged in a valuation or a Level 2/3 Home Survey:

  • Damp suggests the presence of unwanted moisture, which can lead to rot, mould, and structural damage. The valuer will value the property less if there are some signs of damp, and this will likely require further investigation.
  • It can occur due to leaks, rising damp, penetrating damp, or condensation.
  • If any of these are flagged or suspected, a damp and timber specialist should investigate the defect spotted by the surveyor to prevent further deterioration.

Concrete

If flagged in a valuation or a Level 2/3 Home Survey:

  • Properties built with certain types of concrete, particularly those constructed post-World War II, may have structural concerns.
  • Some concrete types can deteriorate over time, leading to cracking or instability.
  • If this is flagged, or a valuer has undervalued the property because of this, a structural engineer or chartered building surveyor will need to come out to assess the property and evaluate the concrete's condition.

Roof Issues

If flagged in a valuation or a Level 2/3 Home Survey:

  • Problems with the roof's condition, such as damaged tiles, leaks, or sagging, can lead to water damage and structural issues.
  • A damaged roof can compromise the property's weatherproofing and lead to costly repairs.
  • If flagged, a roofing specialist should inspect the roof and provide a report. It's important to note that this will only be flagged to the lender and would only be an issue if it impacts the property value.

Tree-Related Issues

If flagged in a valuation or a Level 2/3 Home Survey:

  • Trees near the property can cause subsidence by drawing moisture from the soil, leading to ground movement.
  • They can also cause direct damage to structures through root growth. An arboriculturist may need to assess the risks and recommend appropriate tree management.
  • You can find a local arboriculturist here.

Cost of a Mortgage Valuation​

The cost of a mortgage valuation varies depending on the lender, the property, and the type of mortgage product you're getting (residential, buy-to-let, commercial etc). Some lenders include it in their mortgage package, while others charge a separate fee.

You can expect to pay anywhere between £250 to £1,500, but it's important to check with your lender about this so you're not surprised when a bill comes through for a mortgage valuation.

Where there is a charge, be careful not to add this to your mortgage term otherwise you will end up paying interest on it. Tempting as it is, it is better to pay for your valuation upfront and not to add it to your mortgage value.

You can't use your own surveyor to carry out the mortgage valuation. Your mortgage lender will choose the surveyor. You will usually pay this fee upfront, and it is non-refundable, even if your mortgage application is declined or you decide to withdraw from the purchase.

Remember, this valuation is for the lender's benefit. For your own peace of mind and to fully understand the property's condition, you should commission a separate, more detailed survey.


Do you need a HomeBuyers Survey as well as a Mortgage Valuation?

Yes, we strongly recommend that you get a Level 2 or Level 3, completely separate from your mortgage lender. If you don't, you won't know the true condition of the property. The mortgage valuation is for the lender's benefit, not yours.

A mortgage valuation will not look in detail at any aspect of the property. It is not a survey and should not be relied upon as such. It is a limited inspection to check the property is adequate security for the loan.

A RICS Level 2 HomeBuyer Report or a Level 3 Building Survey will provide you with detailed information about the property's condition, including any defects or potential problems. This helps you decide on whether to proceed with the purchase and, if so, whether to negotiate the price.

If you choose not to have a survey carried out, you could face unexpected repair costs in the future.

All properties in England are ‘sold as seen’ or in Latin: caveat emptor, 'buyer beware'. If you end up buying a property that has damp, subsidence, wood rot, asbestos or infestation, you have to bear the cost to fix it with no claim over the seller unless you're able to prove that there was, for example, damp already there. With no independent survey confirming this, you're left with no legal recourse to sue the seller.




16% of Homeowners Discover Defects

In our recent survey, 16% of homeowners found defects; including 2% who were able to pull out of a bad purchase, 7% who were able to negotiate a better price, and sadly, 7% of homeowners who did not get a survey and discovered defects after the purchase.

12 of the 39 who remembered how much these defects cost to remedy spent over £5,000
