Concrete or gravel driveway for a rental?

[Andrew Pappas]

I currently live in a 3 bed 2 bath Wilmington, NC house in an A- type neighborhood.  I will be moving out in the next year and using the property as a rental and am trying to decide between laying new gravel or installing a concrete driveway.  Most of the homes in the neighborhood have concrete.  I know a concrete driveway won't increase the rent, but is it likely to increase how quickly it rents or sells if I decide to do so?  Any advice is appreciated.
