First offer on house

I got an offer Saturday on the house I am selling. It was a low offer. I tried to meet him halfway but he didn't want to come up much from his price, so I let the offer go.

I've been getting comments that the house looks tired. One of the bedrooms is painted in a kind of psychedelic fashion - it was an experiment in creative painting I did a few years ago. I like it, but I think my potential buyers may be getting turned off by it and seeing it as needing work. So I plan to paint that bedroom in a more conservative colour this week.
