Dog, we've lost about £55k on this sale. There are no guarantees that the market is going to bounce back to when we purchased even in the next 5 years, and there is no way we can afford to do the improvements (we already have granite countertops and hardwood floors etc, we would be looking at high end appliances that we can't afford and would be giving away.) there is no space for conversions or extensions...
This move will mean we will be paying out essentially the same per month, but in a much bigger place where the kids and dogs have a garden, and we have enough space to live - the kids will be able to have people over, have a room each, and there will be somewhere we can sit in peace without being three feet away from a bunch of loud Tweens and teens playing on the wii... And we can get a trampoline to lock Ds on when he needs exercise
.
We thought about it quite hard - £55k is a lot of money to essentially erase - it means that all the mortgage payments we have made over the last six years have essentially been erased - but the benefits are enough for us to suck it up.
Given that we had actually thought that we wouldn't be able to sell this place at all (lots of similar on paper cheaper properties locally - we are curiously high priced until you see the location and comparisons!) we were just so grateful to be able to shift it. We were only intending to live here for 6 months due to the size, so two years has been a long time, and the kids are even bigger now!! We originally bought it as a rental that we could move into when we relocated for a short period. It would be a good rental property, and just big enough for us to use whilst we sorted out jobs and schools, and looked for a family home. It's been pretty good to us, and I will be a little sorry to leave it, but it really isn't big enough.
That said... Last year, when we gave up on the idea of selling, we got rid of all of our spare furniture. Like, all of it. We gave it away, we sold a bit for peanuts, we took our entire spare 3 piece suite to the dump (couldn't get anyone to take it second hand as it was an import with diff fire regs, no so charities or anyone would take it) and now we are moving into a much bigger place with only a 2 bed teeny tiny apartment worth of furniture... 
We are backing onto the mountain, though. So my view out of the back door onto the patio will be almost identical to here, just on the other side of the valley. So it will 'feel' the same.
