Columbia has a genuine historic square with businesses, restaurants and events. That is one of the clearest differences between Columbia and communities like Spring Hill or Thompson’s Station.
But a Columbia mailing address does not mean you are living a downtown lifestyle. Practical walking distance to the square is a much smaller area than the city.
Older homes near downtown can carry real character, and character can come with property-specific questions: age, prior renovations, systems, maintenance, lot and parking arrangements, and historic-district requirements where a particular property is subject to them. Not every older home is historic, and not every downtown-adjacent property carries historic restrictions — verify what applies to the parcel.
If downtown is the reason you’re choosing Columbia, buy the distance to downtown as carefully as you buy the house.
