OOS investing has been a huge headache for me, to be honest.One thing is that a property may pass an inspection but once the tenant is living there and and putting daily stress on the house,  turning on faucets and light switches, turning on heat/AC etc, thing will start to break/malfunction.

We found other two new violations (Not changing air filter causing AC to malfunction and we had to replace it) and (Not Maintaining yard).Is it ok to update the lease violation notices and resend eviction?

If one of those water heaters malfunctions and causes a fire, I'm betting Dawn's insurance won't cover the damage either.

I'm not sure what happened with the furnace but luckily some sort of safety mechanism kicked in to shut the gas off.My concern is that if for some odd reason the furnace malfunctions again (faulty repair, or something else) that she will do the same thing and remove the alarm, not immediately call 911, and go back to sleep with her child in the home.

They also have to find out if anything or malfunctioning or broken and in need of the handyman. 

Tenant will be responsible for all charges associated with malfunction of the system due to misuse.

I was told by contractors that a home may pass an inspection but once someone is living in it and putting daily stress on the house, things will start to malfunction.

As for Electrical, aluminum wiring is a red flag not seeing it can't be used but it has greater chances of malfunctioning and causing a fire vs copper(aluminum was used more in the Vietnam era but this is just precaution), make sure all electrical work is grounded (you can tell if the receptacle are 2 prong and not 3), Service and Panel size would also need to be adequate if you plan on adding more rooms and circuits(I recommend at least 150 Amps).
