Customer Testimonials

Mark and Lorraine have helped us with the sale of two homes and the purchase of two homes. They also did property management on a rental property of ours. They are great at what they do and sincerely care about their clients! We would NEVER use anyone else! They are definitely the go-to people for all your real estate needs!!!

On behalf of Lorraine Costello, who handled the short sale of my house I just want to thank her for her professionalism, expertise, and compassion in working with me to get this short sale done. From start (the initial conversation) to the closing deal, everything went smoothly and quickly and the sale went through without a hitch in less than four months! I have also had the pleasure of knowing Lorraine in another facet of her professional business, as I am currently a tenant in one of the properties that Costello Management handles and she delivers on all that she promises to get done. She returns phone calls and emails in a prompt, professional matter (of which I am grateful for) and I have had zero complaints of how she conducts business. In fact, I have nothing but praise for the Costellos (Lorraine, Mark, and Matt) in how they conduct all aspects of their business.

It has been my extreme pleasure to do business with Costello Realty and Management, a family business with three generations of real estate expertise. As a customer for over 5 years, I am very grateful for their immediate attention to my rental and property woes, and without a doubt, I applaud their energies and time to take charge of emergencies and caring for their customers beyond what is normal. Aloha permeates our relationship and I truly feel the presence of family values with the Costello Realty and Management TEAM! "No Ka Oi" means "The Best" and Costello Realty and Management epitomizes this quality and I am very thankful for their services!!

Have been renting under Costello for 4 months. Never had any problems. Their response time has always been almost immediate. Had several reason to call through no fault of their own and they always contacted me in a timely manner. The online site is great for paying rent and maintenance requests. This morning I requested non-emergency service and was sent an email and a work order was issued within 20 minutes of my request. Very happy.

Mark's grandparents were early settlers of Las Vegas arriving in the early 1920's. Mark's family owned and operated several family businesses. Mark being the oldest of five children, learned as early as 11 years old what a real job was. After many successful years Mark decided to change careers and joined Lorraine as a business partner in the real estate industry. Lorraine's parents arrived in Las Vegas the summer of 1958. Lorraine's mother Eleanore Lamonte began her long time successful career in the early 1960's.
