Perform Final Walk-Thru
The goal here is to ensure no major systems have broken or become damaged since you got the home inspected. So while it may feel a bit silly running around the home flushing toilets and flipping switches, it needs to be done.
6 Things to do during a walkthrough
Open and close all the doors and windows to ensure they don’t stick, squeak, or have new cracks in them. Check walls, ceilings, and floors for any new damage, spotting, or smudges.
Turn on and off every light fixture.
Run water at every faucet and look under sinks for leaks. Flush all the toilets at least once.
Heating & cooling systems
Turn on heat and wait a few minutes to see what happens. Then, turn on air conditioner.
Test all the appliances to ensure they still work (ie. stove gets hot quickly, exhaust fan is sufficiently powerful, the freezer is cold, garbage disposal easily shreds a banana peel, automatic garage door opener functions, etc).
Ensure all debris has been removed from in or around the home and it has been adequately swept up. It may not be perfectly tidy, but it shouldn’t require days of cleaning on your part, either, for you to move in.
