We have known Karen DeRienzo for over 10 years. She has represented us in the rental and maintenance of our condo at The Racquet Club and most recently the sale of our unit. Since we live in Illinois the complete updating of our property was accomplished by phone and emails with Karen. She made the huge undertaking a breeze due to her knowledge and good judgment of the available products, costs and time lines.

Karen is a successful Arizona real estate agent as well as our fantastic property manager. So when we decided to sell our condo, who else would we want to handle the sale but Karen. Once again long distance communications were in order!

Karen walked us through the many documents associated with the listing and sale to our complete understanding. In a very short time the sale went through with a swift and smooth closing. Because of Karen’s business expertise and negotiation skills the buyers agreed to the list price.

We highly recommend Karen DeRienzo and KDR Realty. We have found her to be honest, reliable, hard working and a good friend. Her experience and understanding of the rental as well as the real estate market have exceeded all our expectations.

“We never say never so who knows we may be getting back in touch in the future. We most certainly will give your name to anyone considering time in “paradise.”

However on a personal note, you are a consummate professional and a thoughtful and considerate person as well. Have a good healthy year/life and the same to your family.”

Best Always,


We have had the pleasure of working with Karen for a number of years in caring for and renting our condo.  Having worked with other property managers in the past, we found Karen and her approach to be a breath of fresh air.  She was not solely concerned with finding a tenant and earning a commission.  She gave us valuable insight into possible upgrades and changes that would enhance our unit for us and possible tenants.  She is willing to oversee the process of repair and upgrades to assure that the pricing is correct and the work done to specification.  This is particularly important to those of us who live a distance from our investment.  She is always accommodating and gracious in our dealings with her. Likewise, she treats tenants with respect and concern.   We truly appreciate all she does for us and cannot recommend her more highly.

We have been coming to The Racquet Club in Scottsdale for the last 10 years and have worked with Karen for the last 5.

We find her to be a very professional and accommodating. We have and will continue to recommend her as an agent.

Dear Karen,

Again, many thanks for arranging these 2 bikes et al. You do great work. Hope the remainder of this year goes well for you. We would like to rent these bikes again in 2017.



We have known Karen DeRienzo for over 9 years and we find her to be honest, reliable, hard working, conscientious and courteous. She is pro-active in any and all situations that might arise. Through those years we developed a friendship with as well as trust in Karen.

Karen represents us in the rental of our condo at Scottsdale Ranch Racquet Club. When we decided to update our condo, Karen was our liaison with the contractors as well as with Home Depot. Since we were doing this via emails and phone calls from our home in Illinois, we couldn’t have accomplished this task without Karen’s assistance and good judgment with regard to the products and general design of the remodel.

Karen is a professional Arizona licensed real estate agent and has actively searched out the very best renters for our unit at a rental price in keeping with current market trends. She has always kept the lines of communication open so we know what is happening with our unit as well as the Racquet Club ground in general. We therefore, highly recommend Karen DeRienzo. We feel especially fortunate to have such a reliable person as Karen handling all our long distance needs! Her experience and understanding of the rental as well as the real estate market has helped her to exceed all our expectations.

Karen has been our Property Manager and Leasing Agent since we purchased our unit in 2012. During this time we have worked very closely with her and found her to be a true professional. She has always been very attentive to our needs and those of our tenants. She responds to any questions or request in a timely fashion. Karen makes sure that any services provided by vendors are completed satisfactorily and at a fair price. You can rely on her to provide you the best service possible. If asked, we would highly recommend her to anyone seeking a Property Manager and/or Leasing Agent.

This is our first time that we have dealt with Karen, although we have been a renter here for over 15 years.

She is extremely dedicated to her clients and listen to the concerns. We cannot speak more highly of her sincerity, professionalism and helpfulness. We would not hesitate for a Toronto second to recommend her.
