Many purchasers only discover the problem after their mortgage valuation has been completed, resulting in delays, additional surveys or a declined application. Properties with historic subsidence that has been properly repaired are often mortgageable. Properties experiencing active movement may require specialist finance before they become suitable for mainstream lending.
At AF Credit, we specialise in helping buyers purchase properties that mainstream lenders struggle to finance — including properties affected by subsidence, structural movement, damp, fire damage, spray foam insulation, short leases and other mortgage restrictions.
Yes, but it depends on whether the subsidence is historic or ongoing. Properties with historic subsidence that has been properly repaired are often mortgageable — provided supporting documentation is available. Properties with active movement are much more likely to be declined by mainstream lenders. Where a mortgage is declined, bridging finance can complete the purchase while investigations and remediation are completed.
What Is Subsidence?
Subsidence occurs when the ground beneath a property's foundations moves, causing the building to sink unevenly. This can lead to cracking in walls, structural distortion, sloping floors, sticking doors and windows and foundation movement. Subsidence should not be confused with settlement — the normal process affecting many buildings, particularly older properties — which does not usually present the same concerns to lenders.
What Causes Subsidence?
One of the most common causes in the UK. During prolonged dry periods, clay soils can shrink and compact, causing shallow foundations to move. Most common in South East England.
Large trees extract moisture from clay soil, causing it to dry and shrink beneath foundations. Removing the tree — or cutting its water demand — is often part of the remediation.
Escaping water from broken drains can wash away supporting soil beneath foundations. Drain surveys and repair are a key part of the investigation process.
Historic mining can create ground instability in certain areas. A Coal Authority report will confirm whether mining is a factor for a given property location.
Historic Subsidence vs Active Subsidence
This distinction is critical when it comes to mortgageability.
Movement that occurred in the past and has since been resolved. May include completed underpinning, drain repairs, tree removal or structural works. Many lenders will consider these properties provided documentation is available.
Ongoing movement — often evidenced by progressive cracking, new structural distortion or unresolved causes. Significantly more difficult to finance using conventional mortgage products. Specialist finance is usually required.
What Happens If a Survey Identifies Subsidence?
One of the most common situations buyers encounter is a surveyor identifying potential subsidence during a mortgage valuation. The surveyor may recommend a structural engineer's report, request further investigations, reduce the valuation, refer the case for specialist underwriting, or recommend repairs before lending can proceed. In some cases, the lender may decline the mortgage application entirely.
Will I Need a Structural Engineer's Report?
Often, yes. A structural engineer's report is one of the most important documents when buying a property affected by subsidence. A good report will confirm whether movement is historic or active, identify the likely cause, set out recommended repairs, assess future risk and provide estimated costs. Many lenders will not make a final decision until this report has been reviewed.
Does Subsidence Affect Property Value?
Yes. The impact depends on whether movement is ongoing, the severity of the issue, the cost of repairs and insurance availability. Properties affected by active subsidence often sell at a meaningful discount because mortgage options become limited — which can create investment opportunities for buyers who understand the remediation process and can access specialist finance to complete the purchase.
What Happens If Your Mortgage Is Declined?
A mortgage decline does not necessarily mean the property cannot be purchased. Many lenders simply will not lend while the subsidence issue remains unresolved. Once investigations and repairs have been completed and stability confirmed, the property may become suitable for mainstream mortgage finance — creating an opportunity for buyers using bridging finance.
How AF Credit Can Help
AF Credit specialises in financing properties that mainstream lenders decline. We regularly assist buyers purchasing properties affected by historic subsidence, active subsidence, structural movement, foundation defects and properties requiring structural repairs. Where the issue can be properly assessed, costed and resolved, and a clear exit strategy exists, we can often provide bridging finance to facilitate the purchase.
Structural engineer reports, surveyor comments, contractor quotations for the works, a schedule of remediation and a clear exit strategy — typically refinancing onto a conventional mortgage once stability has been confirmed and insurance is available.
Example
A buyer agrees to purchase a detached property for £425,000. The mortgage valuation identifies signs of historic subsidence and recommends a structural engineer's report. The lender subsequently declines the mortgage pending further investigations.
The engineer confirms the cause was historic tree-related movement and recommends £18,000 of remedial works. AF Credit provides bridging finance to complete the purchase.
Following completion of the repairs and confirmation of stability, the property is refinanced onto a conventional mortgage — repaying the bridge and securing long-term finance.
Why Investors Buy Properties With Subsidence
Properties affected by subsidence often attract fewer buyers because many purchasers rely on mainstream mortgage finance or are put off by the perceived complexity. For experienced investors, this creates a consistent opportunity — purchase below market value, address the underlying cause, obtain insurance and refinance at a price that reflects the resolved issue.
The Subsidence Opportunity: Assess, Repair, Refinance
The gap between the distressed purchase price and the post-repair value is often substantial. With the right finance in place, subsidence properties represent one of the more repeatable value-add strategies for experienced property investors.
Frequently Asked Questions
Can you get a mortgage on a property with subsidence?
Yes, particularly where the subsidence is historic and appropriate documentation is available. See our structural issues guide and unmortgageable property hub for a broader overview.
Can you get a mortgage on a house with historic subsidence?
Many lenders will consider historic subsidence where repairs have been completed, the cause resolved and a structural engineer has confirmed stability. Supporting documentation is typically required.
Is a property with active subsidence mortgageable?
Active subsidence is significantly more difficult to finance. Most mainstream lenders will decline until movement has been investigated and appropriate remediation completed. Bridging finance can provide a route to purchase while this process is completed.
Does subsidence reduce property value?
Yes. The impact depends on whether movement is ongoing, the severity of the issue, repair costs and insurance availability. Once remediated, much of the discount is typically recovered.
Can I buy a subsidence property at auction?
Yes. Auction finance is commonly used where mortgage funding is unavailable or cannot be arranged within the 28-day deadline.
Does AF Credit lend on properties with subsidence?
Yes. AF Credit specialises in financing properties that fall outside mainstream lending criteria — including subsidence, structural issues, damp, fire damage, spray foam insulation and other mortgage-restricted assets.
If your mortgage has been declined because of subsidence, or you are considering purchasing a property affected by structural movement, AF Credit may be able to help. Where the issue can be properly investigated, costed and resolved, we can often provide bridging finance to complete the purchase, undertake the necessary works and refinance once the property becomes mortgageable again.
