What happens if my property has existing structural issues?

Existing structural issues do not automatically prevent a sale, but they must be assessed, disclosed and reflected in the transaction. The outcome depends on the type and severity of the defect, whether the cause is ongoing, the cost of remedial work, the quality of the supporting evidence and whether the intended buyer can obtain suitable finance.

Structural problems can include subsidence, movement in foundations, significant cracking, defective roof structures, failing walls, structural damp, timber decay affecting load-bearing elements and alterations that have weakened part of the building. Some apparent defects are cosmetic rather than structural, so a professional inspection is important before deciding how to market or price the property.

A typical process involves:

• Gathering existing information: Collect previous surveys, engineer’s reports, repair invoices, guarantees, insurance correspondence, planning documents and building regulations certificates. A clear record can help a buyer understand what has happened and what work has already been completed.
• Identifying the cause: Cracks, damp or movement may have several possible causes. A structural engineer or another suitably qualified professional can determine whether the defect is historic, ongoing or related to a particular part of the building.
• Assessing the required work: The report should explain the recommended repairs, any need for monitoring, the likely disruption and whether further investigation is necessary. Obtaining written quotations can provide a more realistic basis for negotiations than relying on a broad estimate.
• Disclosing the issue: Relevant defects and known investigations should be declared to the buyer and conveyancer. Concealing a material problem can lead to disputes, delays or legal claims after completion, particularly if information given during the sale is inaccurate.
• Agreeing a sale structure: The seller and buyer can then negotiate a price and decide whether the buyer will complete the repairs, require further evidence or make the offer conditional on additional checks.

Structural defects can affect mortgage lending because a lender may regard the property as unsuitable security until the problem has been investigated or repaired. The buyer may therefore need a specialist mortgage, a larger deposit or an alternative source of funds. Insurance can also be relevant: a history of subsidence, for example, may affect the availability or cost of buildings cover. These issues can reduce the pool of conventional buyers and make the conveyancing process more detailed.

A cash buyer may be able to consider a property without making the purchase dependent on a standard mortgage valuation. This does not remove the need for appropriate surveys, legal checks or honest disclosure, and it does not mean that every structural problem will be accepted. The buyer still needs to understand the risk and may base the offer on the work required, possible future deterioration and resale considerations.

Before accepting an offer, ask what inspections the buyer intends to carry out, whether the offer is subject to further investigation and what information their solicitor will require. Keep copies of reports and provide consistent information to the estate agent, buyer and conveyancer. If the property is leasehold, check whether the lease places responsibility for structural elements or major works on the leaseholder, landlord or management company.

It is also sensible to avoid starting major repairs solely to make the property more marketable without first obtaining professional advice. Remedial work may not address the underlying cause, and incomplete or uncertified alterations can create additional questions. A specialist report can help establish whether repair, monitoring or sale in the present condition is the most practical option.

In practice, the main choices are to repair the issue before marketing, sell with full details and an adjusted price, or approach a buyer that is prepared to assess the property in its existing condition. The right route depends on the defect, available funds, evidence of the cause and the seller’s priorities. Independent legal and structural advice should be obtained where the issue is serious, disputed or likely to affect insurance or finance.
