So... 

I am writing a post about "Landord Hacks" - it's the little things that a landlord can do to make their life easier, save money, etc.  And I need your help! 

So my question is: What is your best Landlord Hack(s) ? 

I'll give you a couple quick examples: 

1.) Have a hole in the middle of a hollowcore door? Rather than replacing, just buy a $5 mirror at Wal-Mart and screw it to the door. Not only does it hide the hole, it makes the hallway look larger and ads some decoration to a boring space!

So... your turn! What are your best Landlord Hacks? 

Go!
