Honest & transparent

Diana was fantastic, She was always in touch every step of the way. I was albe to text or call & she would always reply lest she was with a client & she would send me a text, "I'm with a client can you please text me". Diana has many skills including conveyancing, with very reasonable rates. Her local market knowledge & accross the board was invaluable. Diana always kept me in the picture whilst looking out for my best interests. Diana proved to be a trustworthy, honest professional which is quite refreshing these days. I would highly recommend her for the sale or purchase of any property & will do so in the future!

A rare gem in the real estate world

A rare gem in the real estate world

Diana was a rare find in the search for our new home, a real estate agent who listens then acts on what she has heard. We were unsuccessful in our first attempt at a purchase. Diana remembered us when a similar property came up and it was a winner. She did everything to expedite the sale and her communication and negotiation skills are top level. Highly recommend Diana whether selling or buying, she will get the job done for you with a smile.
