Built in Space Heaters as Only Heat Source in one Unit

[Justin Schaefer]

Hi, so I'm going to look at a small multifamily today and one of the units has space heaters that are built in to the walls as it's heat source. I don't see any other source at least not on the listing anyway. I've never seen nor heard of this before. Has anyone else ever seen this? Should it raise any red flags? I would be house hacking this one and living in that unit myself for a year and was thinking maybe I could replace those with electric baseboard heaters and install them myself and have an electrician just come wire them. Any thoughts? Thank you!
