If you are going to work in Vancouver, live there. If you want to work in the greater Portland metro area, I highly recommend living in portlad, and near you place of work, or near the school that would best work for your family. There are many people who commute from Vancouver everyday, but they are usually onlycontent to do so if their work place is not far south into Portland, or if their work hours mean there are not going with the rush. Hope this helps!
I would tend to agree with David - the commute will wear you down crossing THE bridge - of course this also depends on what part of PDX you are commuting to for work. I've had friends recently that have sold their home in Beaverton and purchased a much nicer home in Vancouver. Prioritize and weigh out the pros and cons of each and then decide what IS most important to your and your life style. Commuting from Beaverton to PDX can be every bit of frustrating as commuting from Vancouver to PDX.
I would also take into consideration what Katie had mention regarding income TAX and more "bang for the buck" in regards to your new purchase.
Good Luck !
Best way to answer this question is to take the drive across the bridge at rush hour. Driving to Vancouver is a pain!!! With new plans to reconstruct the bridge the drive is going to be a nightmare. The prices may be lower in Vancouver but not worth it. I would be happy to assist you in finding that "right" property, just let me know if I can assist.
