The trick for you is to decide what a minor detail that should be disregarded is, and what something that might affect price and therefore value is. There is no right answer to these questions. It all depends on what type of person is a likely candidate for that particular property, and what features might be important to that person.
In the example for the prior question, our most likely buyer is a young couple with one or two small children or plans to start a family. They are probably on a restricted budget and more focused on functionality than decorative touches. If any of the homes had the following features, I probably would not count them as adding to the value.
• Crystal chandelier in the living room
• Hardwood floors
• Ceramic tile countertops
• Mature trees
You can certainly argue that some or all of them improve the quality of life or pose potential risks to young children. However, the new parents would not pay extra to acquire those features.
Talk to local real estate agents about features that appeal to particular buyer profiles. Experienced agents will have a good sense of those details and be happy to share them with you. After all, the agent wants to establish credibility with you, so you will be motivated to buy a house they have listed. Be sure to talk to several agents, though. One broker with several corner-lot houses for sale might be convinced that corner-lot houses are important to home buyers. It would be good to get a different point of view on that subject before making your own decisions.
