I've overwintered strawberries and other fruits in an unheated indoor space in northern Ohio. It's likely your strawberries will be fine, but I can't guarantee it. However, don't let your strawberries dry out. They won't need nearly as much water in the winter as the summer. The colder it is, the less they need. One guy shovels snow on his potted plants in his garage. As it warms up, the snow melts and waters his plants.

It occurs to me that you indicated you live in Michigan. Upper Michigan gets pretty cold. I would be less confident about your strawberries in those more extreme temperatures. I should specifiy that I live in zone 5. My strawberry plants survived overwintering inside an unheated space.
