No, an IVA protects your property, and you will not need to sell it or risk it being repossessed. An IVA usually requires you to pay back a fixed value every month, often for five years, and provided you keep up with those repayments, your home is not at risk.
Should you fall behind with your IVA repayments, there is a possibility of being declared bankrupt, in which case you could risk your home being repossessed.
