Hear It From Past Clients

  • My brother and I had the pleasure of working with Brennan Harms throughout a difficult process of selling properties after probate had finished, which was extended due to COVID-19 shutdowns. Everyone involved was on edge and emotions ran high on top of the fact that we live out of state and could not be onsite for anything. Brennan Harms did an amazing job. Despite the distance and the emotions, Brennan kept my brother and I in the loop. He was there for every call or call back and always answered our questions in a timely manner. When issues arose, he was on top of it and had solutions for us to consider. I recently have worked with other agents which have not been as on top of everything, where Brennan would come to us with solutions. The other agents I had to bring solutions to them.

    Not all agents are created equal.

  • This is the second time I have had the pleasure of working with Brennan Harms. The first was selling my Mother's home after she passed. He was very respectful, helpful, and understanding as we worked through the process and secured a buyer for the home at a great sales price. Brennan was there the whole time as I went through the paperwork, nicely prodded me when I needed it, and made sure that everything was well taken care of.

    Just recently, I had the opportunity to purchase a home, and Brennan was just as wonderful to work with as the first time! He acted as the agent for both the seller and me, which the seller and I both appreciated. He was truly on top of getting me the contacts for Escrow, Termite Inspection, Home Inspection, and more. All the services had been used successfully by other homeowners/buyers, and all the staff was pleasant and helpful. Brennan followed up on everything, kept me on task, and even helped us close Escrow early.

    I do not hesitate to recommend Brennan to anyone. He has proven to me that he is excellent at what he does, and he is true to his word. Can't ask for anything better!

  • Brennan operates his real estate business at the highest levels of professionalism and integrity. He is organized, responsive, with superior communication skills, ensuring that his transactions close smoothly without any friction. Brennan is proactive and detail oriented with each of his transactions, providing a unique understanding of the transaction process with each Escrow. My team and I love working with Brennan because we know his transactions will close without a hitch, and he will ensure that his clients are provided what is necessary, in a timely manner, in order for that to happen.

    - Dave G.

  • Brennan Harms did an outstanding job managing the purchase of our new home from start to finish. While Brennan represented both the sellers and us (the buyers) in this transaction, he managed to ensure all parties were well represented and taken care through every step of the process. Brennan is an outstanding communicator and was always available to us. We have transacted several properties over the years, and Brennan’s expertise and diligent communication ensured that this transaction was the most smooth and seamless for us to-date. We thank him for all he has done and recommend him wholeheartedly.

    - Brent and Christina B.

  • Brennan, thank you for representing me with my recent investment property purchase in Costa Mesa. You and your team did a great job assisting me with the continuous trail of paperwork. Your quick response to my questions and requests for information allowed us to close escrow within our scheduled time period. It was a pleasure working with you.

    - Mark C.

  • Brennan is an ideal real estate professional.... he immerses himself in the data and understands the market and where each property sits vis-a-vis the competition for buyers and sellers...but more importantly, he combines the data analytics with powerful negotiation skills and an attention to detail that create a trifecta for his clients. His detailed contract work saved me thousands of dollars and optimized the property price.

    - Petra S.

  • Brennan helped me under difficult circumstances right near the beginning of the Pandemic. Not only was he able to help me rent my place quickly, but when the tenants wanted to leave early, and I decided to sell my place, he was there for me every step of the way until we found a suitable buyer.

    - Stuart F.

  • I had the pleasure of working with Brennan these last couple of months. He is the best real estate agent I have ever used. His communication and reliability through this process is amazing. He is always on top of everything and always gets back to us very quickly. I will be recommending him to all my family and friends

    - Val B.

  • Brennan is an absolute amazing young man. Though he had no real reason to, as we were just the tenants, he went above and beyond to make an otherwise very stressful situation for my family and I seamless and smooth. He managed all agents and people visiting our home with a thorough attention to our requests as well as the COVID guidelines like it was a breeze. His communication with my wife and I was phenomenal, and we always could get ahold of him with any questions or reaffirming of what was happening. I look forward to one day giving him a call when we are looking to buy a home.
