Zinsco panel, knob-and-tube wiring, 100-amp service
The one finding that can stop a loan or an insurance binder.
The pre-listing inspection names the panel outright: This electric panel is made by a company called Zinsco. These were very early breaker designs. These panels were noted for design flaws and fires… I recommend these panels be upgraded.
Two pages later it lists the wiring method as Copper, Romex, Conduits, Knob and Tube
and adds Some ungrounded circuits found.
Service is 100 amps. Nobody has traced how much of the knob-and-tube is still live.
The seller's own work history records Replaced faulty breaker in electrical panel
in October 2021. A replacement breaker in a Zinsco panel is the exact failure mode the inspector is warning about.

Two calls before you write the offer, both free: a licensed electrician for a written bid on the panel and the extent of the knob-and-tube, and your insurance broker to confirm they will bind a policy on a Zinsco-and-K&T house. Several carriers decline outright. Because this is a cash purchase there is no lender to catch it for you — and the same issue can surface again at the refinance, so get the binder in writing before you release the inspection contingency.
