Lou and Robert Constable were very helpful and quick with information. They far exceeded my expectations as I thought, with my circumstances it would be difficult. But they have been helpful all along through the process and have recommended them to my son and daughter-in-law.

Rob and Lou have been outstanding in helping us through the sale and purchase of our new home as well as choosing and guiding through the hectic home loan process. Rob took all our worries and stress away leaving us to enjoy the process and our new home. Highly recommend them. Would not use anyone else!
