A friend of mine bought a house in Baltimore County 5 or 10 years ago
that still had knob and tube wiring, at least in the attic. My friend
says you can't get a mortgage if you don't pass inspectinon and you
can't pass inspection with k&t wiring.

What do you think happened?

You've all given me a lot to think about, especially Bud. I guess I'll
have to ask him but because of what I read here, we may have a much
better conversation.

It's possible none of the k&t was still in use when he bought the house.
I saw it in hise attic. I would have kept it as a souvenir but he had
it ripped out.
