A bulk quick buy company has surveyed purchasers who have been deterred from continuing their transactions to discover what the biggest turn-offs are for potential buyers.
It transpires that almost all of the problems are those discovered on surveys and in local council searches - relatively few are visible to the layperson.
Yes HomeBuyers discovered that subsidence is the worst, with some buyers saying it would be the equivalent of knocking 20 per cent off the value of a home on sale.
Second on the list is Japanese Knotweed, the destructive plant that can grow up to 10 centimetres in a single day - although there is debate over precisely how common it is in the UK.
Third comes poor upkeep of a property or its garden, followed by the presence - current or proposed - of power lines, mobile phone towers, or wind turbines.
Following those come nuisance neighbours and flood risks or water damage.
Other turn-offs in the league table include random structural issues, the presence of local power stations, and then more traditional low-level issues - damage or odours left by pets in the home, unsightly clutter, damp and mould, and woodworm.
Yes Homebuyers founder Matthew Cooper says: “Many of these buyer turnoffs can be easily and cheaply fixed, a process which should be well worth the effort and money thanks to the value they will restore to your home.
“Some of them, however, can be very expensive indeed. Severe damp issues and subsidence, for example, could cost as much to rectify as the value they restore. Furthermore, they can take an awfully long time to fix.”
