Just thought I'd update.
We sold our place for £175,000. I'm told the same sort of place (modern purpose built 2 bed flat in Enfield with balcony) was going for £180,000 in April.
What we got was a bit less than we expected but we're not upset as we did make a small profit on it.
For those of you who think everyone in the housing market is making a killing, let me point out that this small profit after costs such as agency fees/lawyers/home improvements/remortgage fees etc (I'm not going to be specific but it was less than £10,000) came after 4-1/2 years of ownership, where we put down a 10% deposit and overpaid every single month by a significant amount.
If we had not seen a 20-25% price increase in house price values and if we had gone wtih a normal 25-year mortgage and not overpaid every month, I'm sure we'd have been showing a net loss, although the costs may still well have been less than if we'd rented.
