They each have their plusses. The main lving areas I would include in your question would be the living room, dining room, den/family room, bedrooms, kitchen. The area of the country also dictates higher resale value. Here in the northeast, hardwood floors (not veneer but true hardwood) are highly valued in all living areas listed above, though depending on the property, not always in the kitchen. Tile, not linoleum, is generally expected in a kitchen, but in some higher end homes, hardwood in the kitchen is very appealing, valued, and warmer underfoot. Area rugs that pick up colors in the room look wonderful on top of hardwood or tile, and soften and warm the colder, harder tile surface, if tile is used outside the kitchen. However, in warm locations or in sandy locations such as near a beach, tile is preferable in all living areas because it is easy to sweep clean, doesn't scratch when sand gets tracked in, and is cooler underfoot in the wamer climates. Grout will darken from dirt, so either use grout sealer to delay it or use a darker color that coordinates with the tile but hides the dirt. If I were you, I would take this information and speak to a few experienced, local real estate agents or home stagers, asking their opinion as to what is most common and what gets the most resale value in your particular area or neighborhood. By the way, here in my location in the northeast, I have hardwood in all rooms but the bathrooms. Minor scratches do occur, but there are no deep gouges or anything like that. They wear wonderfully with a good 3 coats of polyurethane and being real wood (not veneered) they can be resanded a number of times over time, if needed.
