DH and I were lucky enough to move to what was an up and coming London suburb 5 years ago. We have 2 DDs and bought a typical 2 bedroom and 1 box room type terraced house (smallest bed is 2m x3m but with an awkward chimney). It's a great house, we've extended downstairs but can't go into the loft (conservation area and no turning space).
Since we moved, I've gone back to work FT and both our careers have taken off. our earnings are more than double what they were 5 yrs ago. In theory this would all mean we could move to a slightly bigger house right? But not in London where house prices have gone crazy, it seems. Even with the equity we now have, we'd need to more than double our mortgage to move to the next house up.
DH is not keen to increase our debt, I thought we could save and then it wouldn't seem like such a jump. But does the stupid London market make this impossible?
