5 hours ago I didn't know what this stuff was. I agreed in principal to buy a house last week and today I had the inspection. The inspector mentioned the knob and tube and had some concerns but only slight. Said it would cost about $10-15k to replace (3000 Sq ft 2 story home).

After researching more, I'm more concerned. Sounds like it would be hard to insure. Even if I didn't have to replace to insure, I fear I'd have to replace to resell it. And from the quotes other people have mentioned, I think $15k would be on the low end.

I'm heavily considering backing out of the sale. Any thoughts?
