Vast experience in the rental aspect as well as eventual sale of my property

Vast experience in the rental aspect as well as eventual sale of my property

Karl has done a wonderful job looking after my rental property these last 3 years, taking care of any arising issues smoothly and quickly while keeping me informed at all times. When the decision to sell the property was made , his knowledge of the market and his negotiating skills with the buyer were invaluable. It was a pleasure working with Karl and his team and I hope that we will do so again in the future.

Karl explained the scenarios clearly and responded to our calls and messages promptly.

Smooth and Successful Sale Experience, Highly Recommend!

I recently sold my property with the help of Karl at 1840 Real Estate, and the experience was outstanding from start to finish. Karl was extremely helpful throughout the entire process - clear in his communication, knowledgeable about the market, and always available to answer any questions I had. His guidance and professionalism made the process smooth and stress-free. I would highly recommend 1840 Real Estate not only for selling a property but also for their excellent ongoing property management services. I look forward to keeping in touch with Karl and the team for any future real estate needs. He has already gone above and beyond, offering valuable advice for any future property purchases. Thanks again!

Reliable, professional and experienced realtor!

Karl at 1840 has been an absolute dream to work with from day 1. I took a speed dating approach to choosing a real estate agent for the management of my property and Karl and Celeste at 1840 were the most organised and well presented (in addition to the most competitively priced) by far. They are clearly dedicated and knowledgeable in the market, and take a more intimate approach to management. All communication over the past 2-3 years has been seamless, they found reliable tenants, and helped sell my property without a hitch, and securing me a great price. I could not recommend them more highly.
