I can't remember the reason for the move in the first place - is it for work or does your husband just want to move for quality of life/space/etc?
I think you have to both be in agreement. Otherwise, I think it will lead to problems. That's just my two cent's worth.
I was unhappy where we moved last time because it wasn't our desired location - it was what we could afford at the time. The house we made perfect, and we had a lovely spot - so in a way, it was one of the nicest places in our little nook. We ended up making quite a lot when we sold and were able to move to our desired location. The neighborhood ... was not the best though. I knew that going in. It was necessity.
All that is to say - I found it hard. Quality of life means being comfortable where you are and happy to be there. Sometimes you have to sacrifice. I accepted that. I have a lot of friends who have had to move with husbands for careers, etc. You can put up with a lot when needs be - when it benefits the family as a whole.
That's how I would look at it. If the family as a whole is better - and this is a great school for your daughter - then that will check boxes that your current house might not.
It is definitely easier though if you both want the same change and are on the same page. My friends who moved with their husbands were dependent on them for income (mostly my stay at home mom friends). That was part of the deal and they made do and made new friends. Eventually they were able to move back closer to their families again.
Figure out the pros and cons - sit down with your husband and just talk it out. Six weeks definitely is kind of crazy - I am guessing this needs to happen to have your daughter in the right area with an address for school. I don't like making rash decisions, but you did both come to the same decision before for the area - so relief may have been just knowing what you know, and your comfort level is your current home. Sometimes we have to jump out of our comfort zone. Just be sure it's a really family friendly neighborhood/area with lots of amenities and a nice home that you are comfortable with. That will make the transition that much easier.
Added: I can't believe they wouldn't fix the mold problem! Good thing you didn't buy that house ...
