3-4 days is ultra fast if the entire place was trashed, garbage and rotting food, filth everywhere. 3-4 days is ultra slow if the property was left is spotless condition.Like @Randall Brown said, it depends on the condition of the property.

All the other guys send me overpriced MLS garbage that I've already rejected, but at least you are looking for off market property,  even if your lists are obsolete, lol.  

Even if it is just keeping up with the garbage  tenant protections they come up with at every city council meeting - to me it is a matter of how much my time is worth. 

If you can, make sure the tenants keep the outside of the home free from garbage and debris as rodents get real comfortable in any type of junk really.Trust me...be happy its rodents and not bedbugs.  

That book is garbage when it comes to real estate.Read Jason Scott and Mark Fergussons book on real estate negotiating instead.

Rent includes garbage services.

(Water, Sewer, Gas, Electricity, Garbage, etc.) 

When a tenant leaves, they believe the landlord is the "garbage man". 

In some states like GA the tenant is responsible for the lawn care, garbage etc. 

Wash, Dryer, Dishwasher, Garbage Disposal, Chest freezer, etc.But as far as that clause you asked about;  if it were me I would instead insert a clause stating that ALL issues with the property are to be brought to my attention immediately.
