House is a small three bedroomed middle terrace in a fairly poor area in a nice city. This area in a bigger city would probably be considered nice-it's not particularly rough but the houses are small and about half the street are still council owned which is fairly unusual for this city.
We will not be able to afford to move for years-well over a decade I expect, and by that point we'll have two pre-teens falling over each other. We could extend into the garden and into the attic which would be a lot cheaper than moving into a four bedroom house or one with another downstairs room, let alone both.
A very small number of the houses on the street have loft conversions but none have extended into the garden. All the houses were originally two bedroom with a downstairs bathroom and most still are; some like ours have split up rooms so there are three bedrooms and an upstairs bathroom.
Financially speaking would it be a waste of money to add so much extra floor space? I am thinking that even if we could hypothetically add value to the house, would it really rise that much above the rest of the street? I don't think it would, so if we spent £50k (a made up figure but I imagine it would be at least that to do both) the house would never be worth £50k more than the house next door. To give you an idea, houses on this street are worth between £120k-£135k in general at the moment. (Looking at Zoopla and Rightmove, might be less than that.)
Sorry this is an essay. DH thinks we should save and invest in this house. I think we should save and add it to a deposit on a larger house, or one that has more potential for extensions. Who's right?!
