My wife are considering restoring an old house, maybe built in the early 1920s. They style is very similar to the American Foursquare. We would move the house to a new location.

Here's the question: should we re-wire the entire house? And along with that, should we take down all the plaster in order to make the process easier? Now, the plaster is in great shape overall - hardly any cracks. We don't know if the house is insulated, which would be another reason we might want to take down the plaster.

If it makes a difference, the house has not been heated for about six years (We live in northern Iowa with very cold winters).
