Clearing Up a Quitclaim Deed

[Shelby Sample]

I'm in the process of purchasing a property (primary residence)

My realtor just informed me that there is a Quitclaim Deed on the property 

My question is this: wilI I still be able to get Title Insurance and a FHA loan?

Also, will I ever be able to resale it one day or does this cloud the title?

The Sellers agent claims he can clear up the title at closing and everything will be good to go.....should i believe him?
