Karl was really proactive throughout the entire process. We are a really busy family and the team at 1840 took care all our needs. They kept updated every week. All we had to do was sign the documents electronically. Can't get hassle-free than that. Definitely will utilise their service again.

Karl is a terrific, professional operator. This was our first time selling a house and Karl was hugely helpful in guiding us through the process in simple and uncomplicated terms. His communication was first class, and we always felt that he was prepared to go the extra mile for us. We have enjoyed working with Karl and his team for the last 6 years and look forward to continuing a great working relationship.

Great communication and professionalism.

I just sold my house with Karl and the team and couldn't be happier! Great process from start to finish - professional every step of the way, ongoing communication throughout and super easy. I'd highly recommend 1840 RE.

Fantastic Agent and team

Karl and his team at 1840 Real Estate looked after my rental property and also assisted in selling my investment property when it came time to sell. Karl was able to get a great price for me and as I was working away he was able to communicate on a regular basis through out the process which made life very easier for me. Highly recommend Karl and his team at 1840 for property management and sales!

Sound knowledge of the area and quick sale

Sound knowledge of the area and quick sale

Karl understood the area of my property, the market trends, demographics and strategy for sale. This was evident in having over 40 groups attend the 3 open inspections, and selling my property within a week of being advertised at a price above the advertised range. Communication throughout the process was great and hassle free. Thanks Karl

Great work!

Great work!

I rented my property through 1840 Real Estate then chose to sell my house. The whole process was seamless; great tenants, a sales campaign that was timed to my needs and an auction result I was over the moon with😊I trusted Karl and Celeste’s advice at each step and they made my decision making straight forward. Karl’s enthusiasm for the business helped ease any stress related to a ‘big life event’ like selling a house. I fully recommend 1840

professional, efficient and empathetic

Right from the outset Karl's expert local knowledge and professional attitude shone through. His behind the scenes workflow and negotiating skills are highly efficient to the point where we had numerous very appealing offers to consider immediately after the first listed open inspection. Very impressive individual and a pleasure to deal with at all times. Highly recommend !

Thank you so much for the result you achieved. After all the advice on styling and photography, we couldn't have imagined a better result getting an unconditional contract in only 1 week. Happy to recommend you to anyone who wants a dedicated, attention to detail and large on communication agent! Thank you so much :)

We have no hesitation in recommending Karl as a person to sell your property.

We have no hesitation in recommending Karl as a person to sell your property.

We decided to sell our rental property after 3 years with 1840 Real Estate Rental -entirely satisfactory! We therefore asked Karl to be our agent in the sale. From the initial meeting we were impressed by his research and understanding of the market. The price range he indicated was realistic and a contract was signed within two weeks. He kept us informed along every step of the way, which was very welcome and a testament to his commitment to customer service and professionalism.
