If a repossession order is granted and no action is taken, you will typically be given between 10 and 28 days to vacate the property. After that, bailiffs can be called to enforce the eviction. Once the property is sold by the lender often at auction and below market value any shortfall between the sale price and your outstanding mortgage remains your debt, continuing to accrue interest until settled.
The long-term consequences go beyond finances. Research from the Joseph Rowntree Foundation highlights that repossession can affect future borrowing, mental health, and overall stability for years afterwards. The sooner you seek help, the more of this you can avoid.
