I started to mention my concerns above, my brother and I are in our mid eighties, the stairs were very steep and the duplex was over 100+ years! (A Fixer Upper for sure)!
Ian was a nice guy, but he has a lot of work ahead as the place needs many improvements? (Masking tape is one of his favourite tools). The house probably needs an AirBnB inspection in the near future!
