My family and I returned to the NW about 9 years ago and made our move from Dallas. We were completely shocked at the difference in home prices, but were pleasantly surprised when we discovered how much lower our Property Taxes would be here (as Donita pointed out below). Homes here are simply built differently than they are there, so depending on your price point -- you may be surprised when you learn what can get for your dollar. But I will say, that I wouldn't live anywhere else but here - it is simply wonderful!
To provide comparable areas to Austin, well I think that would come down to what parts or neighborhoods of Austin did you enjoy the most? I think you will really enjoy your move to the Greater Seattle area and be impressed with the quality of life you can enjoy and sounds as though that is what you are seeking. Obviously, you liked something about it to make you leave Austin, which in itself is a great city :-)
To keep your husband's commute to Seattle at a minimum (20-30 minutes) will increase your home cost significantly, if you willing to step out a bit more into the "burbs" then you might find more home for you money and still have access to some wonderful neighborhoods and well-respected schools. In my opinion, cities that offer a realistic commute to Seattle and that you might want to consider would be Bothell, Mill Creek, Kirkland, Kenmore, New Castle, Bellevue - they all vary quite a bit but certainly some wonderful neighborhoods can be found in any of these cities.

Public transit is a great option here in the NW is a great option with not only the Sounder Train which can be picked up at a number of locations but North of the city you will find stops in Edmonds and Everett (a little too far north for you, in my opinion). http://www.soundtransit.org
Many people really love the Metro Bus System and Community Transit System here in the NW and you husband might enjoy the ability to catch up on work or sleep on his commute. There are also organized Vanpools that many people share in. So again, great options if you are open to public transport.
Best of luck with you move!
