What to do with wall tiles in... dining room.

[Aref Shehadeh]

Rehabbing a 1930's bungalow. There is tile present on the walls of the dining room, which is the most central room of the first floor. The tile is in decent shape.

Creeping on my rehab budget and would prefer to not demo the tile. Any tips for maybe refreshing the look? (Epoxy paint, acrylic resin). Could this have an ill-effect for home buyers if kept in?
