Are any of the problems in this list deal breakers in your search criteria for rentals and if yes, is there even a way for contractors to fix or mitigate them?

Just my opinion based on having dealt with dozens of them.Your lease should include a list of common maintenance issues that a renter is responsible for: changing light bulbs, resetting breakers, plunging a toilet, testing smoke detectors and changing batteries, etc.

Im fortunate enough my fathers a plumber and with my experience and guys who work with me we handled every aspect, used no sub contractors except to upgrade service to breaker panel.

If there is something wrong with the electrical and you have to remove some breakers, then electrical will not work and the property will be condemned, if a fuse for the furnace blower motor blows and you can not afford to fix it, the property will be condemned. 

Moisture / water / mold, knob & tube wiring, foundation issues, ancient plumbing, rust on the breaker panels, termite tunnels, powder post beetle damage, cedar post supports, improper footings, temporary lally columns, etc.As to writing an offer, that's a sensible and common approach. 

Plain and simple, aluminum is no good for “branch circuits”.

Skipping past other issues to the about to be deal-breaker: We’re past the inspection, waiting on appraisal.

Well that's a real "it depends", and if the layout is bad, you price it accordingly.Bottom line, for me anyway, the only real deal breaker is if the neighborhood is so bad I'm afraid to visit.

It appears Syndication Pro, Ground Breaker and Juniper keep coming up in this thread.

Install some kind of energy meter inside the main panel and track the usage for the circuit the hallway lights are on and just pay that usage and put the meter back in the tenants name.Figure out what is driving up costs and do an improvement program to drive those monthly bills down, caulking, insulation, more efficient heater etc.
