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Dianne actually opened up to the vendors after they had withdrawn from the market at end of their open homes.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

Dianne is a superb real estate agent who skilfully takes you through the whole selling process.

Dianne is a very good communicator: warm, empathetic and clear. She knows the Whangarei Heads/Whangarei market so well as she has lived and worked here for much of her life and that knowledge really paid off for us. We also think that her warmth coupled with her excellent negotiation skills were the standout skills enabling us to sell our house. Dianne is the consummate professional.

Hardworking, honest and reliable

I would recommend Dianne as a real estate agent. I particularly wanted Dianne because of her specialty knowledge and contacts with Whangarei Heads. I found Dianne to be hardworking, honest and responsive. Dianne recommended an Auction for my house which was a positive result, not having any drawn out contracts made the process much easier for me, many thanks Dianne.

Very professional

I suppose you could say it was a strange way to look and purchase a property, but we entered without a viewing appointment, looked at the unit and decided to make an offer - Dianne was very helpful right from the beginning and a pleasure to deal with.
