Real Estate Law Question, Pa

Hello Reddit and thank you in advance for any advice/ guidance you might have.

We bought an old home in the state of Pennsylvania in 2022. During inspection it was noted that there was potentially some knob & tube wiring. (Old ungrounded electric wiring known to be pretty dangerous).

As part of our CTA sellers agreed to “evaluate and remedy knob and tube being used” as we as a few other electrical remedies.

Due to a transfer we are selling our house. It was briefly under contract, but guess what their inspection found? A good bit of energized, very much active knob and tube.

Knowing what I do now, the electrician receipt the sellers submitted for their electrical remedies is entirely too low to have actually done anything with the knob and tube.

Hindsight being 20/20 we should’ve had our own contractors come in but we were out of state buyers, new job, big move. We just weren’t as savvy as we probably should have been.

Title can’t help because the CTA didn’t change purchase price so wasn’t submitted to them (as I understand it, but I might be explaining that incorrectly).

Is it worth pursuing this civilly or is this an expensive life lesson?
