Does it run underground through conduit or overhead?

Assume they are hot, and if they are, those would be incredibly dangerous.If you aren't entirely sure what you are looking at, I wouldn't touch a thing, none of the conduit anything, who knows why all of those wires have been pulled, whats hot, what is being back fed. 

Depends on what ROI you get with the rental vs what you get in the 529.Most states will give a tax deduction for 529 contributions, up to a point, and there's no tax on withdraws for qualified educational expenses.  529s are certainly even more compelling under the TCJA with the expansion of use to K-12.Forget college, all parents with kids in private K-12 should be examining using a 529 as a "conduit account" at the bare minimum to get the state tax deduction.

Should have watertight conduit, not bare Romex. 

Electrical conduit, switches, studs, rafters, subfloor.

New electrical to get it up to code (1 cloth wiring, mismatch breaker, couple oversize breaker, new wire, conduits for water heater line)13.

Our town guy did when the electrical contractor ran the wrong (150ft) of u/ground conduit, so he had to dig it all up & redo it before he could work in the town again, He fixed it fast so the utility could run the electrical cable.

But the homes are merely a conduit to getting lot rent.

Needs new meter and conduit.

If the insulation is substandard/missing, no house wrap, etc, there could be a heat conduit escape route along that seam.
