When applying for a mortgage, the lender will usually arrange a valuation of the property you are buying or remortgaging. Some lenders may include valuation costs within certain mortgage deals, while others charge separately. When lender deals include free survey, they typically means basic mortgage valuation only.
A mortgage valuation helps the lender confirm:
- The property’s estimated market value
- Whether it is suitable security for the loan
- The loan-to-value (LTV) ratio being offered
Types of Mortgage Valuation
Different lenders may use different valuation methods depending on the property, loan amount and circumstances.
Automated Valuation Model (AVM)
An Automated Valuation Model uses computer data and algorithms to estimate property value without a physical inspection.
AVMs are often used where:
- Loan-to-value is lower
- The property is standard construction
- Reliable market data is available
This method is usually faster than a physical valuation.
Desktop Valuation
A desktop valuation is carried out remotely by a surveyor using:
- Property data
- Comparable sales
- Photographs
- Online records
No physical visit is required, but a qualified professional still reviews the information.
Drive-By Valuation
In some cases, the surveyor may visit the property externally but not enter the building.
This allows confirmation of location and external condition while reducing inspection time.
Full Mortgage Valuation
A full mortgage valuation involves a visual inspection by surveyor visiting the property internally and externally.
This is more common where:
- Loan amounts are higher
- The property is unusual
- Construction type requires closer inspection
Level 2 and Level 3 Property Survey
A survey focuses on the condition of the property and may identify structural issues or maintenance concerns.
Common survey types include:
- RICS Home Survey Level 2 (HomeBuyer Report)
- RICS Home Survey Level 3 (Building Survey)
RICS Home Survey Level 2 (HomeBuyer Report)
It typically includes:
- An overview of the property condition
- Identification of visible defects
- Advice on necessary repairs or maintenance
- A market valuation (if requested)
- Insurance rebuild cost estimate
This level of survey does not include detailed structural analysis or invasive inspection. At London Finance Hub, our advisers can connect you with trusted RICS-qualified surveyors. We make private referrals to ensure you get reliable professionals who deliver accurate reports.
RICS Home Survey Level 3 (Building Survey)
A Level 3 survey is more detailed and is often recommended for:
- Older properties
- Unusual construction types
- Properties requiring renovation
- Listed buildings
- Properties where significant alterations have been made
This survey provides a comprehensive assessment of the structure and condition of the property, including potential defects, repair recommendations and maintenance advice. At London Finance Hub, our advisers can connect you with trusted RICS-qualified surveyors. We make private referrals to ensure you get reliable professionals who deliver accurate reports.
Mortgage Valuation for Buy-to-Let Properties
For buy-to-let mortgages, the valuation may also include an estimated rental value based on comparable properties in the area.
Lenders use this information to assess affordability and rental coverage requirements.
What Might the Lender Request?
In some situations, additional documentation may be required.
Examples include:
- New build warranty certificates
- Structural guarantees
- EWS1 forms for certain flats
- Specialist reports (such as damp or timber)
Requirements vary depending on property type and lender criteria.
What Happens If the Valuation Is Lower Than the Purchase Price?
If the valuation comes back lower than expected, this is sometimes called a down valuation.
Possible outcomes include:
- The lender reducing the loan amount
- The buyer increasing their deposit
- Renegotiating the purchase price
- Choosing a different lender
- Reconsidering the purchase
A mortgage adviser can help explain available options in this situation.
Important Things to Remember
- A mortgage valuation is primarily for the lender’s benefit
- It may not identify all property defects
- A valuation does not guarantee mortgage approval
- Lenders have their own property criteria
