Acetone removes glue typically. Sometimes, when you think something is glued in hard, there is an extra screw that you missed.

My garbage disposal just broke. Turns out that the previous owner rigged the dishwasher drain in-line after the disposal, so that there is a chance that disposal water can kick-back into the clean dishes. Fixing that currently.

The kitchen hood vents into the attic, so have to fix that. The owner created a nest of electrical wires in the attic as well, so ended up creating a channel for them and organizing them so they are fastened nicely to the joists.

They created an unstable loft in the garage, so had to demo it since it was ugly as well. The list goes on and on.
