@Jon Klaus you are thinking out of the box!

Has anyone used a mystery shopping company to find out how well your staff is perceived by others?  

Verizon is good for putting the fios boxes on the common electric instead of in the apartment.

For me it's pretty simple:  I want to (a) allocate the cost of hot water to tenants; (b) save on upfront capital costs to keep my budget in tact; (c) provide dependable hot water; and (d) check the box with long term investors I'm targeting for a flip of the property at completion.Opinions are greatly appreciated especially from contractors/investors with low-rise multi-family experience in the northeast US.

If that doesn't narrow it down enough for you, try also including the specific city and/ or abbreviation for it in the search box.  

SO tell them up front, tell them when they can contact you or leave  a message on the door or in a box by the door.

Nothing like a park like setting:-)Sorry I didn't have any suggestions for your buildings that look to be in very good condition, guess I'm suggesting a little out-of-the-box here.Cheers,- Joe

Litter boxes located on tile floors only.

You might consider repainting cabinet boxes and replace doors and drawer fronts.
