Zach and team did an excellent job selling our house in an off season. He defin knows the market, dedicated a lot of off hours time to my needs, and really goes to bat for you when the other side tries to make things complicated. Highly recommended!

Zach is a wonderful real estate agent. From negotiating, home inspection, financing, he made the housing buying very smoothly. He has great knowledge on the communities of northern Virginia. It was a great pleasure to have him as our realtor.

Zach helped me find my first apartment to rent. I gave him the area I wanted to live and my price range and he gave me so many options to choose from with all the things I said I wanted! The process was so smooth and easy, I can't recommend Zach enough. He's personable, knowledgeable, and genuinely cares about finding a home right for you!

When I arrived VA for my new job, I had lots of things happening around, one of those was only finding a house for my family. I wasn't even sure that I can quickly find a rental place, given the fact that I had factors needed to be met for my living place, such as good school for my kids. With what Zach could do for me out from his professional experiences, and very much exceptional good understanding of the market and the local sales, I could have my nice house purchased, in such timely manner and with no hassle that I could do all other important tasks that I had at a same time. I do recommend Zach to anyone who wants an excellent experience for buying/renting her dream house.

Being a person not familiar with the Northern Virginian market since I grew up out of town, I was nervous to start looking for housing to own. I knew I had to rely a lot on the knowledge of my realtor. From the first meeting, I knew Zach was a person I could trust. Not only is he a great realtor and makes the process a breeze, he is a good person and helps you understand everything with real estate and what to look for. I would recommend Zach over and over..and cannot wait to work with him again one day.

There is no one else we would trust in selling or buying our (old and new) homes. With his expertise, Zach made each step in the process of selling our first home extremely easy and we had our house up on the market and under contract within three weeks. This gave us the ability to head into the market to find the right home for our growing family. You know when they say “If you love what you do, you’ll never work a day in your life.”? That’s Zach. Every time we would tour a house for us to purchase, I would over hear him say “I love doing this – this is fun.” Zach helped us find our perfect forever home and I could not be more excited.Trust Zach – he’ll help you find (or sell!) yours like he did for us.

Highly recommend Zach and Stello Homes. Worked with Zach last year and couldn't be happier with the experience! Honest and hardworking.

Zach represented me as my agent during the home buying process. I was a first time home buyer and generally had no clue what I was doing. I actually began discussing the home buying process with Zach literally years before he began officially assisting me as his client. He was always there to answer any questions I had and was knowledgeable about all areas of the process. He is versatile in that he can offer big picture advice which really helped, but also was very good during the search/offer/settlement process with some of the specific recommendations and moves he made as I got closer to closing. Zach’s level-headed demeanor, professionalism, and character really helped make the process easy for me and I appreciated that. Just an example of Zach’s dedication- his wife was essentially in labor during my closing window and Zach still managed to come up with the goods for me! Can’t recommend him and Stello Homes enough.

Zach was incredibly responsive throughout the entire process and provided insight that gave us confidence in our decision making. Zach prides himself on serving his clients; a level of dedication that sets him apart from his peers. When we ran into obstacles along the way, he took immediate action to resolve them with little to no effort from us as the buyers. I would recommend Zach to anyone who is looking for a trusted advisor within the real estate industry, no matter what stage they are in the process. I started talking to Zach months before we were serious about buying a house and he offered guidance and support with nothing expected in return.

Beginning the process of purchasing our first home was absolutely terrifying until we had Zach there to guide us. Having his expertise, professionalism, and personality was an absolute relief and comfort to us. Where we lacked knowledge, Zach covered our bases. When we were unsure, Zach provided the perfect advice. When we were stressed, he made us smile. We never would have found our perfect home without him! Zach, if you’re reading this, you are the BEST and we love you!

There are not enough good things to say about the experience we had with Zach Costello. From early on in the home buying process, when we were not even seriously looking, Zach was checking in with us to determine if our needs had changed, update us on any new prospects that he thought would be a good fit, and answer questions related to homes, finances, and everything else under the sun. Zach's level of knowledge and professional yet personable demeanor made him an amazing choice to take us house to house, looking for any possible defect that he felt would be either a dealbreaker or a possible negotiation point. Once we wanted to pull the trigger on a house, Zach worked very hard (on a Sunday!) to help us put in an offer, which was accepted within 24 hours. Even after acceptance of our offer, Zach was always around to walk us through the closing process and helped answer and alleviate any concerns we had, including helping negotiate the buying of some of additional items outside of the selling price for the house. There are really not enough good things I can say about the work he did, the professionalism he did it with, and how likely I am to recommend him to anyone needing a great agent.

To all potential buyers and sellers:Zach's knowledge and meticulous attention to detail helped me not only get an incredible deal, but made me feel extremely comfortable in closing on my first condo. Zach has become a good buddy and I will be using him again when I decide to upgrade/ invest

Zach helped us buy our first home, and we couldn't recommend him highly enough. Because home-buying was new to us, we had a lot of questions that Zach was able answer promptly and knowledgeably. When we found the right house for us, he immediately provided his insight on the right kind of offer to ensure we didn't lose out on our dream home. Because of his quick action and knowledge of the market in our area, we landed our new home at an exceptional price and couldn't be happier. Zach is thoughtful, responsive, and made the home buying process the way it should be- perfectly painless, rewarding and exciting. Thank you, Zach!

Zach was a class act from the very beginning. He was responsive to all of our questions, had great knowledge of the areas we were looking to buy in and always came prepared with comps and information that he knew we were looking for. As first time home buyers, he walked us through each step which helped to put us at ease. He went to bat for us when we needed, and landed us our dream home! So thankful my fiance and I were able to work with Zach!

Very thankful to have worked with Zach when purchasing our first home. He truly cares about his clients. I had no clue what I was doing or how to go about the process. Zach was extremely professional and helpful through every step of the process. He took us to see multiple properties on short notice, on multiple weekends, and was always prepared when we got to each property. He printed out the details on each property beforehand so he could answer any questions that we had (I had a lot). When we found the right home, he was a tough negotiator on our behalf. We ended up in a multiple offer scenario and came out on top. Even in this tough, seller's market, I felt like we won. Awesome experience, highly recommended. I have already put him in contact with a few of my good friends looking to buy homes.

Zach was excellent to work with throughout the home buying process. He was very knowledgeable, incredibly responsive, and ALWAYS had our best interest in mind, which is the #1 thing you want in a realtor. We looked at many different homes and he never tried to convince us to move forward with anything if we weren't all in. I could not recommend working with Zach enough.

We recently bought our home with Zach Costello, and we couldn’t have been happier or more impressed with how smoothly everything went. He worked with us to identify a creative solution to get the house we wanted at a good rate in a way that was good for all parties involved. He was great to work with - he answered all our questions, communicated with us every step of the way, and made sure we were well taken care of. If you’re looking for a realtor who is honest and very professional but takes care of you as though you are a family friend, don’t hesitate with Zach. We will recommend him to all our family and friends. Thanks Zach for getting us into the home we wanted!

As a first time home buyer, I did not have a lot of knowledge of the home buying process. I was looking for someone genuine, intelligent and hardworking. Zach was extremely helpful throughout the process. I was able to rely on Zach for insight that I would not have otherwise thought about myself. Zach was truly professional and responsive in all communication and he had my best interest in mind. Zach's drive and attention to detail provided me with comfort during the process. He made sure I knew what to specifically look for in the house during walkthrough's, he explained (in detail) sections of the contract that seemed complicated to me, and did a great job communicating/negotiating back and forth with the seller on my behalf. All in all, I highly recommend Zach Costello as an agent.

Highly recommended and would not hesitate to recommend Zach to anyone - deal confidently with Zach!

Zach was the third agent that I worked with throughout my home buying experience. He was awesome - extremely personable and understanding of what I wanted in all aspects of buying. I would highly recommend Zach to anyone looking to buy as he did whatever he needed to do to educate me, get me a good deal, and work at my speed throughout the whole process.

Zach Costello provides an absolutely outstanding service. The major qualities I look for in a realtor are honestly, tenacity and great problem solving skills. These traits can be difficult to find as a package deal nowadays, so before deciding I conducted extensive research on my potential realtor options. Zach Costello stood out to me as the best that the Northern Virginia area had to offer: he is a native to the area, he has a consistent 5 star rating among his clients and a strong social media presence, which indicated to me that he puts tremendous time and effort into his listings.After meeting with Zach for the first time I was reassured that I had made a wise choice. He is an extremely genuine and gregarious family man that is excited about making his clients dreams a reality. He is a highly motivated "go getter" and consistently went the extra mile, while always having my best interest at heart. He left me feeling more knowledgeable and confident in the process and even went as far as creating an eBook titled, "5 Mistakes That Cost Homeowners Thousands of Dollars" which is an absolute wealth of knowledge for any homeowner (whether you are in the market or not). Overall, my experience with Zach was exceptional from start to finish. He exceeded my extremely high standards and expectations and was an absolute pleasure to work with. Thank you again, Zach!
