About Us
Our Commitment

Your Trusted Partner

Established over 40 years ago, MDA Property Valuers is the leading independent authority for certified property advice across the Central Coast and Hunter regions. Guided by John Sheather’s 48-year industry legacy, our family-founded firm delivers legally robust, Certified Practising Valuer (CPV) reports you can trust.

Our value offering is split into two core solution pillars. 

Our History

MDA Property has operated a valuation practice on the Central Coast since 1978, servicing both the Central Coast and Hunter Regions of NSW with specialised appointments undertaken throughout the State. From 1982 to 1998, it practised in partnership with Robertson and Robertson. When this partnership was dissolved, the principal of Michael J. Dick & Associates Pty Ltd, Michael Dick, formed MJD Valuers and sold this practice in 2005. In 2018, John Sheather bought the business and continues to operate under JGSV Pty Ltd.

Our practice clients include the major banks, building societies, finance companies, property developers, originators, solicitors, accountants, and statutory authorities, including the R.M.S. and local Councils. Copies of trade references are available from various companies if required.

Local Expertise. Professional Service.

Our philosophy is built on absolute independence and evidence-based reporting, ensuring you receive completely unbiased, accurate valuations for every property asset. We focus entirely on delivering clear, legally robust advice with the professional integrity and personal service your legal, financial, or personal matters require.
