The exterior doesn’t bother me. The house I grew up in was painted a similar color when I was a teen. The interior is not a place I would be comfortable in. It feels oppressive just looking at the pictures.
What surprises me is the seller is a realtor who bought it as an investment, not his personal home. I thought the usual advise from realtors was to go neutral on colors so buys could envision how they would live in it. I can see this appealing to only an extreme fringe of the population thus limiting sales opportunities.
There are many realtors, but fewer successful realtors. I guess one will find out which this one is.
A side problem is what the neighbors think. They may freeze out using this realtor for future sales. On the other hand, this realtor may only have his license to reduce fees on their flipping. Some sellers may be reluctant to sell their home to this realtor. Perhaps money talks.
