Yes, I agree. Some people are afraid of colour/character in a home because they think people will find it too personal. In some cases, this is true, e.g. if you have some sort of very outlandish decor. However, overall, I have found that most people actually like it.
When I bought my house, I rented out the apartment I had previously lived in and then eventually sold it. The flat had been painted to my liking, i.e. with colour. The living room was a lovely deep smoky blue, one bedroom was lilac, another a sage green and I can't remember now what the other one was, but it definitely had colour! The hallways were all a mint green. There were also some decorative touches there that you wouldn't find in the standard rental flat in London.
I NEVER had a problem renting out that place and certainly never had anyone requesting that I make it more neutral.
