Rental Properties / Knob & Tube Wiring

[Mike Nicholson]

Long time lurker, first time post.  I have question for landlords about knob & tube wiring.  I am a somewhat new landlord, just 2 properties, and in the process of purchasing one now.  The one I am in the process of purchasing is an older house (1920's) and does have the knob & tube wiring, no insulation.  My question is, how many properties do you own that have this type of wiring.  I know this type of wiring is not preferred and can be dangerous however I also hear that there are numerous homes that still have this type of wiring with no issues.  I have gathered a ton of info from past post however I am curious how many you own.  Can I get some insight?

Thanks,

Michael
