An agent that goes above and beyondIn the current market environment, buying a new home is more challenging than ever. My wife and I got to know Andrew and Samatha very well over ~9 weeks of active house hunting. Both Andrew and Samatha kept in frequent contact with us and proactively recommended houses that fit the scope of what we were looking for. We eventually found our perfect home and couldn't be happier.From a buyer perspective, we feel that Andrew and Samantha went well above and beyond to help my wife and I secure our new home. I have had mixed experiences with agents over the years, and based on our experiences, Andrew proved himself to be genuine, honest, reliable and friendly to boot.If you're looking for the perfect agent, whether it's to sell, or to buy, I wholeheartedly recommend Andrew and Samantha. 11/10. Thank you both.

My experience with Jared McGovern at Obrien Real Estate Langwarrin has been nothing short of Exceptional. He has gone over and above in his duties as the selling agent to ensure I was able to understand every part of the buying process. Being from Sydney it was foreign territory to me, however Jarred never waivered from his professionalism. His ability to relay all of the information to me gave me every confidence in the process at hand. I could not rate my experience any higher and strongly recommend anyone looking at selling or buying to get in touch with Jarred as you are guaranteed to receive nothing but 5 star service.

Jared McGovern and the rest of the O'Brien team I've had contact with have been great to deal with in purchasing my new home. They have been very professional and responsive.

Jared was great. Worked tirelessly to help us buy our property even during a lockdown. Nothing was too much trouble & even provided great after sales service.

Andrew Guerin in the last year.

When not working hard for his clients Andrew enjoys spending time with his wife and 2 children, swimming at the beach with his beloved dog and generally enjoying everything that the Mornington Peninsula has to offer. 
Being a fully Licensed Estate Agent Andrew has the knowledge and credibility that buyers and sellers are after.  Having worked in the Langwarrin/Somerville areas for many years now, Andrew has developed an extensive network of clients whom look to him for professional advice on all real estate matters.  “The best thing I can do for my clients whether buying or selling is to offer them 100% service”.
Andrew’s love of houses and real estate dates back to his days as an Architectural Draftsman.  Having worked for some major companies and organisations such as AV Jennings and the State Government of Victoria, Andrew decided to take the leap into the real estate world and completed his degree in Business (Property) at RMIT.  After working for several years in commercial real estate he felt the strong desire to move back to the Peninsula to enjoy “a more relaxed lifestyle”.
