Buying a property with knob & tube wiring

[Thomas Long]

Starting to invest in multi-families in Central MA. Obviously lots of properties are 100+ years old and my current issue if finding active knob & tube wiring in the houses. Most of them have been MOSTLY replaced but still finding some live wires in the houses.

My concern is if there is some I can see there may be much more behind the walls that didn't get upgraded either.

Do any of you invest in properties with knob & tube? Do you replace it all or find insurers who will insure it (my go-tos don't and I expect the rates to be very high but haven't actually been able to get quotes yet).

What type of discount do you expect when you find knob & tube wiring? Do you get quotes or just ballpark it and ask for a much larger discount than you expect the repairs to cost?
