I'm currently selling a colourful condo but....the Seller has smartly kept the colour to her accessories, art, & furniture against a neutral palette for walls & floors. That means Buyers can move in with any style or colours that suit them without changing a thing.
Buyers can be put off by strong colours or even just colours that they dislike. It means another step for them to try & visualize it differently, another obstacle to a possible sale so be smart about your choices.
I love people who embrace colour in their lives, but if you're thinking of selling in the next few years & it's time to paint, think carefully about where to put your favourite colours. You can enjoy it just as much if you use artwork, pillows, & other accessories to make it your own. Bonus-you get to take it with you!
