Selling a property with defects: disclose or repair?
Every defect is either repaired, priced, or discovered. Choosing which is the whole job.
A property with a known defect has three routes to a sale: fix it, price it, or hide it and hope. The third is not a route, it is a delay — the buyer's survey will find it, and a late discovery is far more expensive than an early disclosure because it happens after you have turned other buyers away.
Choosing between the first two is an arithmetic question. If the cost of repair is less than the discount a buyer would demand for taking the problem on, repair. If the discount is smaller, disclose and price.
When repair is the better answer
Buyers discount defects by more than they cost to fix, because they are pricing uncertainty, disruption and risk as well as the work itself. A £5,000 roof repair is routinely treated as a £10,000 or £15,000 problem in a negotiation.
That asymmetry is the argument for repairing anything with a known cost and a known contractor. It converts an uncertain problem into a clean property, which widens the buyer pool as well as removing the discount.
- Defects with a known cost and a straightforward fix: a failed roof section, a broken boiler, damp from a blocked gutter
- Anything that would make the property unmortgageable, because that collapses the buyer pool to cash buyers
- Anything a lender's valuer would flag and require a retention for
- Cosmetic problems that photograph badly and cost little to resolve
When disclosure and pricing is better
Some defects cannot sensibly be repaired by the seller — because the work is disruptive, because the cost is large relative to the price, or because the buyer will want to address it their own way as part of a wider scheme of work.
In that case, disclose it, provide any reports you have, and price the property to reflect it. A buyer who knows about a problem at the first viewing is a buyer who has accepted it, and the sale is far more likely to complete.
The legal position
There is no general duty to volunteer every defect in a residential sale, but there is a duty not to misrepresent, and the property information form asks direct questions that must be answered honestly. Answering them falsely gives the buyer a remedy after completion, and the cost of that is far higher than the discount you avoided.
The practical position is that a seller should answer honestly whatever is asked, and disclose anything material that a buyer could not reasonably discover for themselves. That is both the safe course and, in practice, the one that produces a completed sale.
Common questions
- Do I have to tell buyers about damp or subsidence?
- You must answer the property information form honestly, and it asks about these specifically. Beyond that there is no general duty to volunteer every defect, but misrepresenting a known problem gives the buyer a remedy after completion. Disclosing early and pricing accordingly produces a completed sale more reliably than hoping the survey misses it.
- Should I fix a problem or reduce the price?
- Compare the cost of the repair against the discount a buyer would demand. Buyers usually discount defects by more than they cost to fix, because they are pricing uncertainty and disruption too. If the repair has a known cost and a known contractor, doing the work is usually the cheaper option and it widens the buyer pool.
