Structural issues don’t make a house unsellable. They make it unsellable to most of the buyers an estate agent will introduce. The distinction matters because the strategy a seller adopts depends entirely on which buyer pool they’re aiming at, and the wrong strategy can cost months of marketing time and tens of thousands of pounds in failed transactions.
If you’re sitting on a property with subsidence, a cracked chimney stack, a failing roof, or any of the half-dozen issues that mortgage valuers reliably flag, the question isn’t whether you can sell. It’s which route makes the most sense for your situation.
What Counts As A “Structural Issue” When Selling?
The phrase covers a wide range of problems, and not all of them carry the same weight at survey stage.
The Major Ones
Subsidence, heave, and landslip sit at the top of the list because they affect the foundations directly and trigger immediate caution from mortgage lenders. So do significant timber decay (dry rot, wet rot, woodworm in load-bearing elements), cavity wall tie failure, and Japanese knotweed within seven metres of the building.
The Mid-Range Ones
Roof problems (slipped tiles in volume, sagging ridge lines, evidence of long-term water ingress), large cracks above 3mm in load-bearing walls, and failed chimney stacks fall into a middle category. They’ll be flagged on a Level 2 survey and almost always on a Level 3, but the mortgage outcome depends on the lender, the severity, and the survey report’s wording.
The Often-Overlooked Ones
Damp, particularly rising damp or penetrating damp reaching internal load-bearing elements, falls into structural territory once it starts affecting timbers or causing wall movement. So does inadequate underpinning from previous work, missing or defective lintels, and asbestos in older builds.
What Has To Be Declared, Legally?
Anything material to the buyer’s decision must be disclosed on the TA6 Property Information Form. Section 4 asks specifically about structural movement, alterations, repairs, and known defects. The Misrepresentation Act 1967 and the Consumer Protection from Unfair Trading Regulations 2008 both apply, and a buyer who discovers undisclosed structural problems after completion can sue for damages or, in extreme cases, rescission of the sale.
Sellers aren’t required to commission a survey or investigate problems they don’t know about. The duty is to disclose what’s known, not to discover what isn’t. “I don’t know” is a legitimate answer where it’s genuinely true, but evasion that crosses into misleading the buyer constitutes misrepresentation. Painting over damp patches, hiding crack monitors, or removing knotweed cosmetically without treating it can escalate to fraud under the CPRs.
Why Do Structural Issues Cause Sales To Fall Through?
The honest answer is that mortgage lenders are conservative by default and become significantly more conservative when a survey flags structural concerns. Most chain-dependent sales hinge on the buyer securing a mortgage offer. When the survey raises a structural issue, the lender’s options are to refuse the mortgage entirely, reduce the amount they’ll lend, or require remedial work to be completed before drawdown. None of those outcomes are quick, and most of them end the sale.
Even when the lender holds, the buyer typically renegotiates. A 10 to 20 percent reduction is common, and sometimes more depending on the issue. The seller is then faced with a choice: accept the reduced offer and complete, or refuse and start the marketing process again with the structural disclosure now formally on record.
Surveyors are also more thorough now than they were a decade ago. The chance of a structural issue staying undetected through a Level 2 or Level 3 survey is low, and lenders increasingly require Level 2 minimum on properties over a certain age. The era of slipping problems past the buyer’s due diligence is largely over.
What Are The Options For Selling A Property With Structural Issues?
Four practical routes, each suited to different circumstances.
Repair Before Selling
The traditional advice. Get a structural engineer’s report, scope the work, get quotes from approved contractors, complete the work, get a certificate of structural adequacy or PRC certificate (depending on the issue), and then put the house on the open market with the documentation to hand.
This works well when the issue is contained, the repair cost is reasonable relative to the property value, and the seller has the cash to fund the work upfront. It’s less attractive when the repair is expensive, when the seller needs to move quickly, or when funding the repair would require borrowing against a property the lender is reluctant to value.
Insurance Claim And Sale
For subsidence and certain other insured perils, the insurer may fund the remedial work. The complication is that mid-claim sales are difficult: the buyer’s lender wants the claim closed and the work signed off; the insurer typically wants the property sold to a like-for-like risk. Sellers can end up stuck between the two for months.
Auction
Auction can produce a fast sale on a property with structural issues, and the buyers attending auction are typically investors and developers who expect issues and price accordingly. The downside is the unpredictability of the final hammer price; sellers occasionally do well, often achieve fair value, and sometimes see properties sell for less than they hoped. Auction houses also charge fees, and the seller may need to fund a legal pack before the sale.
Direct Cash Sale
A specialist cash buyer assesses the property as it is, factors the structural issue into the offer, and completes without a mortgage or survey dependency. This is the route most sellers come to after exhausting the others, and it tends to be the right answer where speed and certainty are more important than the last few percent of market value.
At Property Buyers Today, we buy properties across the full range of structural issues, from minor historical movement to active subsidence to severe damp and timber decay. The offer reflects the property as it actually is, including the work the next owner will need to fund, rather than agreeing a number and then trying to chip at it after a survey we’ve already arranged. Sales can complete in seven days where the seller needs that speed, with all legal costs covered.
How Do Cash Buyers Price A Structural Issue?
Cash buyers factor in the cost of repair, the time the repair will take, the holding cost during that period, and the difference between the eventual repaired value and the unrepaired purchase price. Most of the figures involved are known quantities; structural engineers can scope the work, contractors can quote it, and the timelines are reasonably predictable.
A typical structural issue might add £30,000 to £80,000 in repair costs depending on the property and the issue. The discount applied to the purchase price reflects that cost plus the buyer’s margin and the time-value of the money tied up during the repair. The result is usually a sale price somewhere between 70 and 85 percent of the open-market value the property would achieve once repaired.
That discount feels uncomfortable on paper, but the comparison isn’t with the repaired value: it’s with the alternative path of months of failed sales, repeated renegotiations, holding costs, and the eventual sale to a different buyer at a similar effective discount.
The Bottom Line
A house with structural issues will sell. The variables are how long it takes, how many failed transactions sit between listing and completion, and how much the seller eventually nets after the various costs of trying to push it through the mortgaged market.
For sellers with time and capital, repair-then-list is often the route to the highest headline number. For sellers without either, a direct cash sale removes the variables that cause most structural-issue transactions to collapse. The right choice depends on the specifics: the nature of the issue, the urgency of the move, and the seller’s tolerance for uncertainty across a multi-month process.
If you’re trying to work out which route makes sense for your property, we’re happy to talk through it with you. The conversation costs nothing and gives you a concrete number to compare against the open-market alternative.
FAQs
Will a buyer’s survey always find structural issues?
Almost always at Level 2 and Level 3. Surveyors are trained specifically to identify the things that affect mortgageability, and the documentation requirements have tightened in recent years.
Can I sell with subsidence even if remedial work hasn’t been completed?
Yes, though almost certainly not on the mortgaged market. Specialist cash buyers and auctions are the realistic routes.
Does insurance pay for selling a house with structural issues?
Insurance funds the remedial work where the issue is a covered peril (subsidence is the main one). It doesn’t fund the sale itself or compensate for the discount you might accept on a quick sale.
How long does a structural-issue property typically sit on the market?
Properties with declared structural issues commonly take three to six months longer than equivalent unaffected properties on the open market, and a significant percentage never sell through the conventional route.
What’s the difference between a structural engineer’s report and a homebuyer’s survey?
A homebuyer’s survey is a general condition report, usually carried out by a surveyor. A structural engineer’s report focuses specifically on the structural elements and is the document mortgage lenders want to see where structural concerns have been raised.
