But once again, with the clock ticking, I'd need to set the wheels in motion soon.I would appreciate any advice.Thanks,Matt

I would consider putting a cheap wifi security cam inside the front door to get notified of motion. 

Someone dies in a fire because you didn't provide smoke detectors.

The typica test includes a magnometer (super duper metal detector) as well as looking for signs of a tank (vent or fill pipes, cemented over holes in the foundation wall where the lines came in, etc).

My husband just went down in our tenants basement to replace the smoke detector and discovered water marks from a very obvious recent flooded basement.

I have a code enforcement inspection each year and the biggest issue is usually smoke detectors and any other safety violations.

And two of the units don't have carbon monoxide or smoke detectors.

I’m in the same situation, I’m having tenants go through all the motions.

What types of routine or emergency maintenance will it need (water leaks / exterminator / smoke & CO2 detector maintenance / air filters / gutters / outside maintenance / paint / flooring / refresh between tenants, etc.).

@Isaiah WilliamsShort answer: do not do anything with your LLC until you have a business plan in motion.
