About Mandy

Originally from Cobb County Georgia, I've had the opportunity to travel and live all over the United States! Experiencing professional relocations and homeownership in multiple regions presented me with a well-rounded knowledge of real estate investing and a deep appreciation for building wealth through homeownership. My professional background in sales as well as extensive experience as a facilitator and project manager with top U.S. corporations, have provided me with the communication and negotiation skills necessary to make the sales process seamless, efficient, and transparent every step of the way. My corporate background deeply ingrained the necessity of professionalism and the importance of embodying a strong ethical code of respect, honesty and integrity in every aspect of my business. I believe that by prioritizing the things that matter most, and providing my clients with individual, prompt and knowledgeable service, my business has flourished from referrals and repeat business.  With my relocation days behind me, North Georgia has been my permanent home for more than 8 years. I enjoy participating in many organizations including East Marietta National Little League, and volunteer roles throughout the Cobb County School District (former Reading Bowl Coach - voracious reader!) - I can credit the majority of my involvement to my three children!  Additionally, I serve on the Board of Directors of East Marietta National Little League, and am an active member of East Cobb Church and the Cobb County Board of Realtors®.  B.A. in Business, Multi Million Dollar Club, New Home Selling Expert Designation, Listing Agent, Accredited Buyer's Representative

A Wonderful Professional to Work With: Mandy Costello

A Wonderful Professional to Work With: Mandy Costello

Mandy Costello worked extremely hard to help me find a home in close proximity to Emory University that I could afford. She was very patient and methodical in serving my needs. I highly recommend her as a realtor, and would hire her myself if I sell my home at some point.

Great agent!

Great agent!

We had an excellent experience working with our real estate agent. One of the things we appreciated most was her non-pushy approach, which made us feel comfortable and in control throughout the process. She was consistently clear and honest in her communications, providing us with straightforward information and guidance every step of the way. This level of transparency helped us make informed decisions and truly trust in the advice given. We highly recommend her to anyone looking for a trustworthy and effective real estate professional.

Excellent Organized and Knowledgeable!

Mandy was very knowledgeable and extremely organized and helpful throughout the entire process. She kept us informed as our home was being built and frequently checked on it by visiting the site and making videos of the progress along the way. She worked well with the builder and the other real estate agent. We are so grateful for her and all she did to help us from start to finish!
