With an all-cash deal, you also save by avoiding loan origination fees, an appraisal, some closing costs and other charges imposed by the lender. You enhance your negotiating position with the seller and get to bypass the rather lengthy loan qualification process, which helps to close the deal quickly. But if you want to use the home as your primary residence, forget about taking advantage of the tax breaks available to homeowners with conventional loans. By paying cash, you basically forfeit those tax breaks.
