I doubt that it will help with resale unless the spaces are uncomfortable without fans. If you need them to keep the spaces comfortable, then, by all means, install them.

You might check with the National Association of Realtors. They track some kinds of data about what helps with resale.

Thanks for your input. I didnt think it would help with resale especially since we have a ceiling fan in almost every room in the house....and Im going for a more contemporary look.

As HERE Design mentioned, it depends a lot on your location, but even then not everyone likes ceiling fans. We only put them in the bedrooms of our new house, but I debated on whether I wanted them or not. If you don't use one at night for comfort, I wouldn't put them in.
