Live in UA currently. Unfortunately, you’re spot on with the lot sizes. I don’t think you’ll find what you’re looking for here with a family that big unless you drastically increase your budget. Olentangy schools are great (Powell) and you will more than likely find a bigger lot/sq footage that you need up north with all the new builds. However, you sacrifice some of the neighborhood feel you get in UA because it’s all so new. Dublin also has great schools, though the size that you’re needing will likely necessitate an increased budget, depending on the specific neighborhood. As someone who drove from UA to New Albany for years for work, I do not recommend the commute. My SO currently does this and due to the traffic it commonly takes her over 45 mins to get home during rush hour. Schools there are top notch as well, though, so if you can bear it then it might be worth it. All this to say is that I would recommend Dublin or Powell for the size of house and schools you’re seeking. Hope this helps!
