We put tower cranes on hotel projects, 4-10 stories, that are built with pre-fab metal panels.

@Justin Cabral For what it's worth, I was recently at an investor meeting and they had a panel discussion on the state of the economy.

No blinds, no shades, no hurricane panels, no burglar cage...All this for $50 at The Home Depot for this fancy multifunctional window.

If a tenant is renting a 3 bedroom home, and reported that one of the rooms had a leak 6 months ago, but became uninhabitable as of 3 months ago (can’t figure out where the problem lies and outside paneling is going to be coming off to search further), should they receive a reduction in rent?

Most of my properties have accordian style sliders so pretty easy but one house has those heavy panels that one took a good 3 hours as the tenant apparently used some of the panels and attached them to wood fence gates to stop his dog from passing below, and a few other panels for other purposes. 

That would save you on every cost but the panels themselves.

My experience with a "professional electrical inspection" typically involve looking at the meter weatherhead "visually", taking down the electrical panel cover and look inside and see if there is any cause for concerns (double tapping, mismatched wire gauge & breakers...), testing and resetting of one or two kitchen GFCI receptacles, plugging in a few receptacles with their $10 tester and making sure the "CORRECT"s are lit up. 

The downstairs would be up to code for everything but a separate swicth panel, which would need to be done.

I hire one for plantation shutters installation, they brought a crew of 3 staff to hang 4 panels.  

I don't want to upgrade breaker panels and they don't want design network infrastructure, but in Maryland, you must have a Master or Limited Electrical license to pull a permit for low voltage installations.
