There is a log home we have been in negotiations to purchase. But we ended in a stand still. Price was way over what that lake property would be. But we are back looking at it again but I have some questions my realtor can't answer. Its in Minnesota...how energy efficient is a log homes? Its 2400 sq feet with the walk out basement. Also there is one very main log in the center of the house with a deep crack running all the way down the side. Log is the beam running from one side of the house to the other side. Would that crack further? It was built by Pioneer log homes that does Timber Kings on HGTV. The logs are 24-36" around so huge...is that good or bad? What upkeep should I expect if we get this house? Thanks for any help. I want this one, my husband doesn't.
