paper on ducts
About the Electrical, as long as the Aluminum is terminated properly (means correct wire nuts used, correct wall switches, breakers rated for AL/Cu, Receptacles, NOX used on all bare Aluminum ends) is safe. That means that you are in a position to have the Home Owner either pay to have it inspected & signed off by an Electrician stating the condition the wiring & panels are, or have them pay to have the wiring updated, this may include putting in new Circuit Breaker panel if fuse panel is in place, or unable to get ACFI breakers for current breaker panel, the Seller gets to pay for the costs.
Our house had the Asbestos paper on all of the joints on the old Octopus, and since we had our new unit put in, the duct work that had it is no longer there, because it was removed from the house. The key here is, as long as you do not disturb the Asbestos, it is not a problem. If you really like this home, and have truly fallen in love after taking some time to allow "Buyer's Remorse" to pass, then speak to an attorney to work with the Realtor to get the problems solved.
Do not let the Seller's Home Inspector or their recommended Electrician give you the info about the home, pay for your own uninterested third party that is paid by you to do the Home Inspection & Electrical Inspection. If you want, you could go as far as hiring a reputable plumber to look over the plumbing, or a GC that does all aspects. The key here is, do not go by the party that the Seller or Seller's Realtor recommends, because again, who is getting paid, it is not you.
