The main difference between a grant deed vs. Warranty deed is the level of protection offered.Unlike a general warranty deed, a special warranty deed doesn't cover title claims over the property's entire history. A warranty deed transfers your ownership and explicitly promises the buyer that you have good title to the property. A Beneficiary Deed works a little differently. The grant deed is similar to a warranty deed but does not include additional guarantees. A warranty deed pledges or warrants that the owner owns the property free and clear of any outstanding liens, mortgages, or other encumbrances against it. Grant deeds are considered better than quitclaim deeds , but less desirable than general warranty deeds . A Warranty Deed is the best type that a purchaser of property can get. In a warranty deed, the seller guarantees they hold a clear title to the property and are legally able to transfer it.
