Benefit to seller if buyer uses cash vs conventional financing?

[Josh VanLandingham]

Newbie question here... From the sellers perspective what are the benefits of a buyer offering $100k cash vs $100k through a conventional mortgage lender? The obvious one I understand of giving the seller the option to close within a very short period of time (less than a week). If the seller doesn't care about the time to close, what are the benefits to him/her? Thanks for any clarification on this.
