I will hopefully not be as naive, as I apparently have been about the dark side of what must be so many millions of people. 

I don't charge for paint (unless they painted the room some dark color that makes me do additional coats of paint). 

The thing that would concern me the most are the smoke detectors in the common areas (hallways and basement). they are supposed to be hardwired and connected. if one goes off all of them should go off. fortunately for you that is something easy to test.

I just added a window air conditioner to one apartment unit and the cost to increase the electric panel and wiring was $6,500 because the inspector made us install wired smoke detectors, GFI's in the bathroom and kitchen and we pretty much has to re-wire the apartment. 

I have since legalized the basement suite by adding interconnected smoke alarms, sprinklers in the mechanical room and applying for development and building permits.Location: Huntington Hills, CalgaryRent: Main Floor $1325 Basement Suite: $950 Garage: $300 Total: $2575Net cash flow: $460 What made you interested in investing in this type of deal?

I added sprinklers in the mechanical room, wirelessly interconnected smoke/co alarm (with hard wired power connections) in the basement bedroom, mechanical room, living room, staircase and 1 upstairs, development permit with the City of Calgary because the lot was zoned RC-1, building, plumbing and electrical permit for the renos.

Replaced the furnace for a high efficiency one, ran CAT6 networking to all rooms, enlarged and replaced 4 of the basement windows, replaced the suspended ceiling for drywall, installed 11 (yes 11) interconnected smoke alarms and sprinkler in mechanical rooms, repainted basement walls, replaced one of the rooms flooring, added gravel to the 3 parking stalls (currently was dirt).

No smoking within the unit2.

Let's drink, smoke, or have coffee and enjoy a face-to-face meeting like old times.

Light up all the yard and dark corners and it will be another deterrent.
