My go to is: Paint, outlets, fixtures, flooring, and appliances. 

Keep in mind that most places go by electrical code which requires an outlet for every 2 feet or more of countertop.

Since then, of course, the area has gone nuts with attractions, outlet stores, and the like. 

First, get rid of all of your 3 prong outlets and replace with 2 prong.

Stop was the message.Then they put too many things on one outlet with an extension cord--extra refrigerator, microwave and coffee maker and portable dishwasher. 

I replacing old wiring, outlets, and leaking plumbing.

Besides flashlight, measuring tape, telescoping ladder,outlet tester, and electronic thermometer\ moisture detector what else should I pack.

I'll keep a flashlight, measuring tape, and occasionally an outlet tester on me to check for grounding, reversed polarity, and the tape for measuring room sizes to ensure conformity to bedroom standards (height, fsqft). 

It was so bad that we’d find dead bodies behind trim, inside outlets and light fixtures and stuck between window sills.

I know you said it has been rewired but I would still be checking lights to ensure they are grounded it's easy to skip grounding lights and replace outlets simply to make it look like a bigger job was completed.
