Seriously consider renting out the current home. See if your realtor can help you with the calculations, but at ~30minutes away, you're not too far to make periodic visits as needed. You'll be able to deduct repairs, improvements, interest, transport/travel, insurance and taxes, among others. Run the numbers for various rental charges and assuming your annual expenses for the above list. You'll be surprised. Plus, you'll gain the property's appreciation over time. Actual out of pocket costs yearly may not be much at all... and you might be right-side up, depending on your rent at the new place.

Or... stay where you are and become a multi-modal commuter 3 days a week. Drive 2/3 and bike 1/3 of the distance. Mix it up.

How does your wife feel about the current house? Is she up for the adventure of a move?

Good luck.
