About Us

Costello Realty & Management Company is a family owned Las Vegas business. Owners Mark and Lorraine were born and raised in Las Vegas, NV.


Having lived here all their life, they have extensive knowledge about Las Vegas, Nevada and its real estate market. They know the strengths and the opportunities of this region, and that is why they can help you capitalize on these opportunities so that you can maximize your returns.


When we began operations, we initially offered only realtor and sales service. However, as we built a good reputation within the industry. As our clients started to trust in our services, they began to ask if we would be interested in managing their residential properties. We decided to add the property management division to our business and we haven’t looked back since.


Today, we are a full-service real estate company that believes in old fashioned values and integrity. It is our commitment to do right by our clients and to ensure that every aspect of real estate management is done in the most effective and efficient manner.
