Recently, I met some friends who have lived in the same home for 30 years. I actually think it's neat that they are still in the same home. Some of my friends have parents who have moved to senior living communities and they purchased the parents' home and are living in their childhood home with their growing families. I am sure lots of improvements have been done over the years and repairs as needed. Many older homes are in GREAT locations with bigger lots and while newer homes are more modern they are usually on smaller lots and are a little farther out away from city centers.
In other situations, some people move more frequently from one home to the next because of family circumstances or career changes. In most of these situations, living in a home for even a few years allows them to become accustomed to defects that are not really a problem for them, but for a new buyer may present an issue. Too many small items could add up and actually be a deal breaker. Although they may be small and incidental issues to the seller, those possible repair dollars add up to a buyer.
If you and your family live in a house long enough, there may be items that need to be repaired that you haven't considered because you have gotten used to working around the problem. For instance, a sticky door or broken lock seems like a very small issue. Maybe the door company no longer exists or you are unable to find replacement parts or locks. I would suggest getting a home inspection before your home hits the market to benefit both sides of a future deal. I assess each listing and when necessary, and I will provide this option as part of my professional service on older listings to help the homeowner avoid any surprises.
