Specially if you are going with stone countertops, you need sturdy base cabinets.

You can - and should - give them a written list of rules like no barking, always keeping the animal leashed or under control, cleaning up after it immediately, etc.

When I walk my dog I have a fannie pack, as it's really impractical to have a purse with a dog on leash.

Consider a new amenity for your rentals.......a backyard kennel, doggie playground, big bone door mats, doggies doors and walk in tubs with leash attachments!

If it is low, or you don't charge for her pets (you said dogS) - then I would be frank and let her know that you can add a pet fee to help cover it or she will have to leash her dog when she lets it out.

Just for kicks, check out this "simplified" guide to low voltage installer licensing requirements in CT:http://www.casiact.org/assets/2016-simplified-guid...Here in WI, up to 24 volts I believe it is, NO license is required and we see some of the same messes and I'd agree with the other comments, as landlords we MUST keep an extremely tight leash on ANY sort of installs like these and I've seen the "cable guy" do much of the same and it doesn't matter if its some dump about ready to fall over or an incredible, truly classic home with a stone or brick exterior, they'll normally just drill right through the exterior (good for the masonry drill bit companies!)

Letters tend to get a better response rate than postcards so I would focus on really trying to give them a solid sturdy mail piece.

One ladder at one side of the room, the other ladder at the other side of the room, and the walk board between the two.Takes a minute extra time to set up for each room (Rotate the whole assembly on right angles as you move around the room), but when doing cut in at a ceiling it beats the pants off the old grind of "Paint 3 feet, climb down, move the ladder, climb up, pant 3 feet... wash, rinse, repeat"(Of course, I'd rather have stilts, but not everybody will invest that kind of money in tools)This is a sturdy setup that will cost maybe a hundred bucks at maximum (No need to buy really expensive ladders to do this), and will save you a ton of time... especially in hallways!

An apartment owner friend mentioned that the newer laminates and vinyl look much better and are more sturdy. 

A lot of those old stone foundations are actually quite sturdy.
