It is only natural for property owners to fall in love with their homes over the years as they live safely and happily with their families. As they rack up fond memories their home becomes more and more valuable to them. This is great, at least until it is time to sell their house. They let these feelings influence the price they think they should get for their home.
This is a challenge for retail real estate agents who want to list their house at a price that will sell quickly based on comparable sales. The homeowner will feel that their home is superior to the comparables because love is blind, and theirs is worth more.
This is problematic and will cause a delay in getting the property sold.
