Anyone with common sense would paint over the “art” before trying to sell. If only because people will ask for a discount as they’ll have to redecorate. Yup! Regardless of anyone's assessment of their taste - and you do put your home up for judgement and even ridicule when it goes on the market - the first thought of every potential buyer will be "How much will it cost to get rid of that?"
Making your home stand out for the wrong reasons won't help sell it at a good price, or quickly!
