Would an underlayment I lay down myself be a better or worse option than the pre-installed underlayment or no underlayment and insulate the dropped ceiling below for noise reduction if needed?

Complex electrical issues other than fixture change outs, ceiling fan changes, basic diagnostic stuff (garage doors for example often have simple fixes) and breaker resets.3.

Additionally, the MLS listing reported there were new ceiling fans in each of the rooms but there weren’t any!

I guttered alot of walls and a few ceilings, painted, left it empty during this for 2 months.

You have damage all throughout the kitchen; cabinets, floor, wall, behind the wall, ceiling, can't use the appliances, not to mention the smell of smoke that's permeated throughout. 

Looks to see how many coats of paint/ primer I need to put on for the different wall / ceiling materials. 

If there are no water issues on the ceiling the diverter is the solution.

I’m not sure for in Brantford but I know in Kingston wether it is a duplex or triplex, i’d go to the city and they will have multiple forms listing your next steps, everything from entrances to ceiling height.

Be careful for the things that are hard to see; under the trailer, above the ceiling, etc. 

I'm just about to start my first house hack duplex rehab project here are ideas I'm considering:-high efficiency toilet system-ceiling fans in bedrooms and main rooms-electronic keypad door locks-programmable thermostat-programmable electric bathroom baseboard heater
