The ceiling mounted ones can be a bit more tricky as they may require a water pump to move condensation up and away. 

Out by Mount St Vincent, things are a little better priced.Fredericton is also quite fully priced, but things are starting to ease on residential (1-4 unit) properties.  

It's very handy if it's a ceiling mounted alarm to not having to get on a chair to press the test button.Some alarms actually work with ANY infrared remote control devices. 

It was $200 to install so it wasn't a big expense.The house my son rents in Colorado has a ring type doorbell and the owners mounted a small monitor on the wall in the hallway close to the door so my son can see who's at the door.

Test the ceiling smoke detectors and power outlet mounted carbon monoxide detectors every 2-3 months (by pressing and holding the test button till it beeps; if it continue the beep periodically after the test, the battery needs to be replaced). 2.

Some LLs write into their leases that wall mount TVs aren't allowed, or that tenants have to have mounts professionally installed & leave the mounts at move out.I'd be afraid some installer will put a hole thru my plumbing in the wall.

If there are no easy ways to climate control the converted sections from the central unit, it wouldn't have been difficult to have gone with a window unit for AC and wall mounted space heater. 

My "why" for getting into real estate investing is actually because I want to get back into competing with 1-3 mounts, and ultimately being able to afford a small horse friendly property that I can bring my critters home to for rest/retirement.

Local codes in my area now require fire extinguishers and that they be mounted on the wall in the kitchen.

I also built a set out of some run of the mill poplar and painted them (yuck) HGTV "country white" or whatever with the basic contractor knob set and regular corner mount non-soft close slides.
