In Decatur, this gap is closer to the national average.

These include: time spent vetting contractors and getting multiple quotes (the average homeowner spends 8-12 hours), temporary accommodations or lifestyle adjustments during work, increased insurance premiums after major renovations, and property tax reassessments triggered by permitted improvements.
