We are recently under contract on a new construction that we really love. In the past, I've saw parents and friends struggle with small garages and have been interested in a bigger garage. We've asked about upgrading our 2 car garage that they quoted us as 19x20 to a 3 car garage and they are asking $15K for the upgrade. Does this seem a bit high to others? The difference between a 2 and 3 car in construction costs from scratch doesn't seem to be that much, but I just wondered if I was being taken for a ride here. We are in the Nashville area if that helps. Thanks!
