The HIP Alliance is a grouping of local property professionals. PSG in association with the majority of local legal firms is able to provide a first rate service. You may find a HIP a little cheaper elsewhere, but a HIP is an important legal document and compromising on quality is a false economy when selling your home.If produced by professionals with local knowledge of your area, a HIP should speed up the sales process. A poor quality budget HIP might cost you a sale, due to delays in the conveyancing process caused by inaccuracies or corners being cut in the HIP.
