While your home is only required to be left in broom clean condition, it’s common courtesy to either clean the home yourself AFTER you’ve moved all of your stuff out or have a cleaning company come and clean it. This needs to be done after your stuff is all out, but before closing occurs. Ideally, it’s best if you’re moved out AND the cleaning occurs before the walk through. The walk through usually occurs the day of closing.
If you would like for me to arrange for someone to clean your home, just let me know.
