Listened and then got what we needed within 4 weeks.

Dianne was onto it. We were selling as powers of attorney for a dear friend. Fast competent compassionate sale. She had the contacts. Worked very well for us and ensured a secure future for our friend. Great work from Dianne and her team.

Dianne fulfilled our needs in every aspect

Dianne actually opened up to the vendors after they had withdrawn from the market at end of their open homes. She was able to get us into the home again, to allow us to make them an offer. Her communication with us at all times was really appreciated
