DP & I love our house - but it needs a bit of reworking to make it more suitable before we have little ones. We've had some architects round & now know we would need to do a pitched roof with dormer window instead of the flat roof we'd hoped for (it's a second storey extension over an existing single storey) which may double the cost. We just don't have the cash to do that - but if we don't extend we have to move.
Would we be silly to consider borrowing roughly £15,000? We've got a mortgage but not tonnes of equity as we only bought 18 months ago. I'm self employed and DP is employed so it would be in his name. I've found some very low interest deals like 3.5% fixed over 5 yrs - which seems ideal! This way we can crack on without having to wait 5 yrs to save (which also means waiting to TTC).
Is this a terrible idea? Looking for outside opinions as we've never done anything like this before!
