Plaster Walls Repaint or Replace

[Mitch Atkins]

Hey Everyone hope the Holidays are treating y'all well. My Christmas present was a investment property in Greensboro NC, it's an old mill house built in 1929. The inside has plaster walls and I'm asking if anybody has experience dealing with them. I can paint over them but I want to know any other options and cost of replacement. Thanks. The goal of this house is long term buy and hold or the BRRR method.
