Or hire a property manager.Extra construction material from rehabbing stays in a plastic shed/bin on the property (paint, extra tile, etc.) or immediately goes on Craigslist or is returned.

It has a patio and bedroom, garage, off street parking places and even a pool!

The next would be to put a "plastic" coating over the existing.  

Around $3.00 for patios and walkways.

Thanks,Gry  I would "spin" the closure of one of the pools, saying that you are creating a quieter apartments area and will be creating a garden area or patio area, etc. 

Go to re-light water heater after gas was turned back on and the plastic knob on top of the gas valve where pilot light is turned on is missing.  

Give them a heads up before doing treatment with what the pest guy says needs to be done,, trash, put food items in plastic containers,, ect.If they don't comply give them notice to move, non- compliance with terms of lease, cleanliness. this could infest your entire building, and I would have pest guy treat all neighboring apartments. 

Get a basic "handyman toolkit" in a formed plastic case.

Run out to Bed Bath & Beyond and get a bathroom trash can that a plastic liner fits in with a nice fitting lid.

Sometimes a simple change to the grade around the foundation can fix the issue or if there is a cement side walk/patio, make sure it’s sealed.
