The in-laws dropped a surprise on the family this week by telling us that they want to move out of their 2 bedroom bungalow (always going to be their last property) which they are finding increasingly difficult to keep on top of due to ill health and purchase a smaller wardened accommodation. They have the money to purchase the 2nd property outright and so selling their current bungalow isn't an immediate concern but at some point they will want to sell. Back in 1999 about 6 years after moving in they found that the front porch which they had built was starting to drop on the front corner, the property had to be underpinned and the cause which was a huge tree in the copse to the right to them was removed. Since then there hasn't been a single issue as the FIL being involved in the building trade all of his life has kept his eye on it. Does any body know what complications this will cause to any future sale or letting? We've read that you’ll likely have to accept a 30-40% reduction in the value due to this. Does anyone have any first hand experience of this?
