Thank you all for your answers and help!! I'm a bit nervous about this move and you all made me feel better. For those who have lived in NoVA, the commute is hurting my husband. It's easily an hour each way and now they are talking about moving him downtown so add on 30+ more minutes. We will love about $100k when we sell this house but to us it will be worth it for quality of life.
Thank you all for the tips on the school districts as well. When we've moved in the past it was pre-son so we didn't care about the schools. Thinking about the school makes the whole process more challenging. As for class size mentioned, it would be heaven! right now my son is in the 3rd most crowded elementary school in the county with 7 classes of 2nd graders with 27-28 kids each class and 126% capacity. It's a mess but they make it work well. But my son needs handwriting help and we have to pay a tutor since they don't have the time or recourses to help him during school.
As for houses, we are a bit picky after living here. We made a mistake and didn't rent when we moved here and the neighborhood is not what we expected. But simply, 4 bed, 3 bath, basement (I see a lot have them there which we love) and would love a mud room for all those snow clothes (I grew up in upstate NY so the snow won't bother me but my husband who grew up in GA is a whole 'nother story!). And I would love a neighborhood with a pool but so far I haven't found many. Is that the case?
I will keep you all in mind if he gets the job and contact you for more info as we know more. This is an exciting and nerve-wracking time for us and I'm glad I have people who know to help me
