It’s not just NH. First house I ever owned was in Massachusetts. Two family with coal burning furnaces that had been converted to gas. The furnaces and steam pipes were covered with asbestos. Bathrooms had claw foot tubs. 60 amp electrical service with fuses.

Eventually, I had to replace the furnaces and my contractor refused to do it unless I had the asbestos removed first. That was expensive. I sold that house long ago to a flip this house type who converted it to condos!
