A cash offer gives the seller a lot security: It means the buyer has the money ready to complete the purchase right away. This makes the process faster and easier since there's no need to wait for a mortgage to be approved. Also, a cash offer is more attractive to sellers because it reduces the risk of the sale falling through if there are problems with financing. Sometimes, a cash offer is seen as more appealing because it eliminates certain fees that the seller would otherwise have to pay, like mortgage origination fees or appraisal fees.
