Bridget Daly the Property Manager is very supportive, prompt, efficient and excellent professional service since the start of the service that we required for renting out our property. following up on service to provide which is not seen with other real estate properties we have been with. very happy with the service indeed. so asCourtney Smith, at this real estate is very efficient in service to our property for rental purposes. keep us up to date on what's happening, as to what's the next step. we don't have to follow up on it which is lacking in other real estate agents services. very happy so far for the wonderful service they provide us.

It was our first investment property. So far great experience with O'Brien real estate ,Cranbourne. A great place to start with. Never felt any difficulties throughout the letting process. Our property managers were excellent . Special mention to Brooke Barnes, our property manager whenever we have some enquiries she responded promptly with clear explanations. Everything exceed our expectations.

Our experience with O'Brien Real Estate Cranbourne was nothing short of exceptional - Daniel, Andrew, Candice & Tiarni went above & beyond to help us buy our first home.They have been clear & communicative about the process, always responsive to our questions & requests, up front about what to expect & what is required & committed to an amazing level of attention to detail every step of the way. You can tell they have great insight & wisdom when it comes to understanding the property, the market and both the vendor and the buyer perspectives. All of these attributes are so valuable, but were made especially so during lockdown with all the limitations that Covid adds.As first home buyers we were pretty nervous & wary - you hear so many stories about how dodgy real estate agents can be (especially in a booming market) but it was genuinely the best experience we could possibly have hoped for & we are so grateful for all of their hard work.Could not recommend them more highly - thanks for our wonderful first home!
