All separate heating systems installed in 2014.  

Be sure to have one installed and have it wired to the light switch, ideally with a delay so it keeps running for a few minutes after your tennat took a nice hot shower.Also, make sure you educate your tenant about mold and why it's growing.

Would the house be easier to rent if I installed a washer and dryer?

This is not the popular option as it costs money to replace it outright but I typically spend $800 or so installed.

Hi,Does any landlord here install security cameras on the outside of their properties?  

If this happens 5 years after you install the tile, you may not be able to find the same style of tile or grout.

Yes, I always install it if it is missing or broken even though my property is in the low end range property.

I had to replace the new installed carpet in the entire house in a few properties after the tenant stayed there only 1 year.

They are not properly draining far enough from the house and part of them are not installed properly.

Having faced this situation before, my initial plan was to install a second meter in the basement and simply split off the plumbing.
