Taste is such a very personal thing. As a previous writer mentioned, if you're needing to update a floor in order to sell a home, talk to your realtor about the best, most cost effective options. It's very difficult to anticipate a home buyers preference. However, in working with many buyers and sellers in 55+ communities, this is what I've noticed: Buyers tend to like tile in high traffic or "water" areas like the kitchen and bathrooms. For living spaces such as great rooms, family rooms, living rooms, dining rooms, laminate/wood is preferred for their appealing warm wood tones. Bedrooms seem to be a toss up between carpet and laminate/wood with nice looking rugs.
Speaking of rugs, if you're not using carpet in a 55+ home, be sure to place rugs strategically and securely to increase safety in the event of a fall, and to prevent tripping hazards. And one more thing: if you do decide to use ceramic, have the tile set on the diagonal. It opens up rooms and makes for a less boxy feel.
Hope that helps.
