I bought my 2 bed house in 2007, 100% mortgage. I completed on the day I went into prem labour with ds1 who sadly died 6 days later. We only planned one child hence we bought 2 beds. Fast forward 11 months and we welcome boy/girl twins. They have happily been sharing but as they approach 9 we really need to move to a 3 bed property. The house is still in negative equity, not by much. Anyone have any advice how to proceed? No spare cash around .
