What The Kallner Collective's Clients Say

If I could give Kathy & her team a 10 ☆ review I would. I was actually referred to Kathy by the realtor in my home state. I am from Seattle and was looking to buy an investment property in AZ. From start to finish Kathy was amazing. Not only is she the type of person anyone can get along with (so so personable), but I was amazed with how efficient she was. She truly listened to what I...

Amy T.

Us being international home buyers puts a different level of requirements needed from the agent that we use. We sit in a time zone nine hours away and in many cases we have to completely put our trust in the hands of our agent. Kathy Kallner and her team showed at an early stage that they were up to the task. Outstanding service and flexibility combined with mutual trust were the key ...

Goran C.

I was referred to Kathy through a friend. I’ve never met someone more compassionate to help me find a home for me and my family. She listened to my needs and never hesitated for a second to go the extra 100 miles when it counted and proved to be only in my best interest, not hers. Her experience and connections in the industry have only proven beneficial when it comes to thinking outs...

We have bought and sold a few properties with Kathy! We have also recommended her to several friends and we have all had the same experience, she is the BEST!!! We would not use any other agent! She has gone above and beyond for us!! Love her!!

Patty S.

I had the pleasure of meeting Kathy in February '21 and she immediately exceeded my expectations with her professionalism, area knowledge and the market's crazy climate. She is a tough negotiator and knows how to build a strong offer. Kathy is quite possibly the best realtor in Arizona.

Scott L.

Kathy is persistent, has great communication skills and has excellent strategies for maneuvering through the buying and selling process. Her experience in the market place gives her clients an advantage over less experienced agents. Her positive personality keeps things light even during stressful times We would not hesitate to call in her again to help us. We have recommended other f...

Kathy did an amazing job with the whole home buying process and made sure it got done in 30 days. She did an amazing job and highly recommend her to anyone looking for a new home.

Kathy went above and beyond for us and we found the perfect investment for retirement!! She knew everything and then some. Highly recommend Kathy Kallner!

Debra

We worked with Kathy to purchase a home when our daughter was traveling across the country to attend ASU. Kathy worked closely with us to make sure we found a condominium complex that was safe, convenient and also represented a good investment. After our daughter graduated, and with all the uncertainty of the global pandemic, Kathy and her team were able to help us sell the property. ...

Troy I.

I’m from South Carolina and I was looking for a home in Phoenix. I needed someone who could provide me with detailed information on properties in various locations around the city that matched my price range and buying criteria. I knew nothing about the local market and had a timeline to meet. Kathy was recommended by a mutual friend and I couldn’t have been more pleased. She present...

Home Buyer

Over the last couple years, I worked with several realtors handling both the sell-side and the buy-side. Kathy stands apart with her knowledge, responsiveness, and professionalism. She recently helped me buy a home in what can only be described as a very challenging environment for buyers. Kathy was "all over it", staying in constant contact with all the various parties and giving me ...

Tom S.

Kathy and her team were great to work with - they guided us through the home buying process when the market was on fire and gave us the best advice on how to have an offer accepted. 100% recommend working with these great folks!

Dawn M.

STOP SCROLLING! You have found the only realtor you want to represent you when buying or selling a home. Kathy is by far the most exceptional real estate agent in the valley. She makes the entire process effortless and treated us like family along the way! I wish I could rate Kathy 1000 stars on Zillow. She deserves it! Don't think twice. Give Kathy a call. Thank me later!

Jordan S.

The housing market is tough, but Kathy is tougher. Once we were ready, Kathy hit the ground running and got us set up in her very stream lined process of house hunting. She’s very responsive and works non stop. When we made our first offer, Kathy got us the best deal a buyer could get. And even after we’ve closed and moved in, Kathy and her team are still here for us. We highly recom...

Craig W.

We have been looking for an Arizona home for a long time, Kathy has always kept us in the loop of what was happening in the market. Her attention to detail is extraordinary and her responsiveness was greatly appreciated. We would highly recommend Kathy and her team.

Jeff W.

A few months ago, we decided to downsize and sell our home. We reached out to Kathy because we had worked with her previously when we bought our home in 2005. She had done a great job for us then and we knew we could trust her advice in this fast moving market. Kathy helped us make smart decisions regarding our remodel so that we could put our home on the market well positioned to att...

Barry S.

Kathy is one of the best realtors we’ve worked with ever. There are many reasons why she was so highly recommended. She knows the area extremely well, understands the market, has developed a great network of supporting contacts, and expertly negotiated our position leading to a quick and smooth closing. We recommend Kathy to all our good friends and professional contacts. She is Scott...

Edward S.

Working with Kathy Kallner and her team on the sale of our condo was really fantastic. They are professional, very experienced, knowledgeable of the market and really easy to work with. They make the process seamless and handle all the details. They are always accessible. I highly recommend Kathy Kallner and the Kallner Collective team for your real estate needs.

-Lou V.

Kathy has been our go-to realtor for our last two homes sold and one purchase. She has been wonderful to work with as both a buyer and a seller. Her professionalism, knowledge and personality make the process easy and fun. She got us beyond top $$$ on both of our sales, and a great negotiated rate on our purchase. Kathy is absolutely my first call for my real estate transactions!!

Robert G.

When I needed a realtor for my first home buying experience, Kathy came highly recommended from a friend that has worked with her multiple times in the past. From the very beginning, Kathy was responsive, professional, and listened carefully to my needs. Kathy was extremely positive and made me believe we would find the perfect house, which is exactly what we found! She received prais...
