@Ray Thorsen I would look a doing a white or light grey shaker style door on the uppers to make the kitchen brighter

Lighting - Its florescent lighting - I want to go brighter bulbs for sure but should I upgrade the lights themselves?

The spirit shines or illuminates on a flashlight like the one from a camera.5/ Call the ExpertIf you have your journal ready with enough evidences, it’s time to call a Paranormal or parapsychologist expert for further investigation.6/ Perform a house cleansings:If you're a Christ Follower and empowered by the Holy Spirit, the authority of Christ (Luke 10:17-20), you could easily perform a spiritual house cleansing.

But then I found a flashlight that someone left up there back in 1972 or so and it pretty much made it all worth it. 

Besides the places you looked, the serial numbers on some mobile homes are etched into the frame -- you'll have to literally climb under the home with a flashlight to see if you can find them.

Several tool boxes with wrenches, screwdrivers, pliers, socket sets, flashlights, spare batteries, nuts and bolts, screws, electrical repair parts, multimeters, copper/pvc/galvanized plumbing repair materials. 

I might have painted the front brick to make it look brighter from the road! 

Get better lighting if you want it brighter inside.Lead paint is tricky.

I add a lot of bourbon and everything looks brighter afterwards! 

A reasonably good handyman will just take off a cover plate, inspect with a flashlight, check with an outlet tester, and let you know immediately if the installation is unsafe.Good luck to you.
