Mark is so amazing and is super quick! I sent him a house I was interested in, and he immediately scheduled a showing for the next morning and the offer was in before the end of the day. He also had so many resources and contacts to ensure a quick and easy transition to becoming a homeowner. With Mark I was able to get all of the home repairs done before the settlement date which was a huge help. Mark helped me to buy my first home quickly and efficiently and I wouldn't recommend him enough!!

Mark is an amazing, dedicated, and knowledgeable realtor. We decided to work with Mark due to him helping multiple family members and being referred by all of them. So, we knew even before working with him that we were in good hands – and he certainly did not disappoint! Mark helped my husband and I (first time homeowners) navigate purchasing a bank owned property during a time when it is hard to buy. We were looking for something in our budget that we could renovate and rent out a portion of, so we had very specific requirements. Despite the tricky market, he got us a good deal on the property that met all our needs! After winning the bid, he helped us navigate the intricacies of buying a bank owned property. He was always prompt to respond and on top of every detail. We would gladly work with him again! Thank you Mark!

We hired Mark to be our sellers agent 2 1/2 years before we finally found a home to purchase. During that time, Mark was very helpful in working with us to get our current home ready to put on the market. When we finally found the home of our dreams, he went above and beyond to get our house on the market in an extremely short window of time. As a result of his efforts, we were able to get the house under contact after 4 days on the market and at a price that was well over asking price. Mark was extremely knowledgeable, well connected and hard working. I would highly recommend Mark!

Robin & I have the privilege of working with Mark through our business - Robin Ford Building & Remodeling – as both buyers & sellers and we can wholeheartedly attest to Mark’s professionalism as consistently shown by his responsiveness & attentiveness to questions and concerns as well as his extensive knowledge of the area real estate and market conditions. He is diligent in his explanation of fine print details and communicating changes and developments as they occur in this quickly changing & challenging market. Mark not only goes above and beyond to prepare your home to show at its very best with professional photography, designer staging and touch up recommendations but also to prepare his clients for the process.

I first met and worked with Mark in the Spring of 2021, when he helped me purchase our first home in Maryland. Not only that, but he walked us through the entire process while I was physically in Hawaii, even through closing. The time he takes, energy he puts in, and just overall care he takes with his clients in my opinion are almost unimaginable!
For these reasons, when I decided to sell that same home he had just helped me purchase two years prior, I knew Mark was the guy to help me not only sell that one, but also purchase the new home that Brandi and I fell in love with earlier this year.
If you're looking for a Realtor who genuinely cares about his clients just as much about the job he does in representing them, an unmatched work ethic, and a true passion for what he does, then Mark Ruby is your guy!! We can never thank Mark enough or speak highly enough of him as a Realtor and as a person.

Mark was on top of the details. He said he would have a offer in
four days. We had multiple offers in that time over the asking price. I had lived in my house with my wife for 40+ years. After she passed a few years ago it was time to move on. As Mark would tell you, it was not easy for me to sell and move. He made it work and calmed my emotions. Need a real estate agent? Call Mark Ruby.
Thanks Mark

Mark Ruby sold our daughters home several years with a quick turn around. They were extremely pleased with his service. So we contacted Mark to discuss the selling of our second home. We found Mark to be very attentive, he answered our questions in clear and concise words and we felt comfortable turning over the sale of our home to him. Mark always responded to our questions daily. He offered suggestions and options we never even considered to attract future buyers to our home. His knowledge of the real estate business and his familiarity with our community helped to establish a realistic asking price. His estimated price to sell our home was within the range we were expecting. We established a time-line and Mark hit all the deadlines from "Coming Soon" signs in the front yard, orchestrating pictures of our home and advertising in many different areas. Our house officially went on the market on Friday and we had several contracts within the first four days. We actually sold our house for more than the asking price which was icing on the cake. We would highly recommend Mark to anyone interested in selling their home.

My wife and I recently bought our dream home and this would not have been possible without Mark. He helped us go through every step of the home-buying process, from narrowing down the right neighborhoods to settling on our new house. His knowledge and experience proved invaluable. As first-time homebuyers it was hard to compete in today’s market, but Mark knew exactly how to craft the perfect offer that ended up beating several other offers. He has a plethora of connections, such as mortgage brokers and home inspectors, who helped the home-buying process run smoothly. He worked weekends and evenings to ensure we met crucial deadlines. We are so grateful for Mark and cannot recommend him enough!

Mark was very helpful to me because it has been over 40 yrs since I had to sell my home. He made excellent suggestions to help make my home as appealing to a potential buyer as possible. Mark always let me know when potential buyers were coming. He worked very hard to make sure everything went perfectly for the closing process and I was able to get the full asking price for my home. I was very pleased with Mark's ability to get my home sold.

My husband and I could not have asked for a better realtor to work with! Mark helped us purchase our first home two weeks ago. Our home was the first house we toured and put an offer in on. Without Mark's expertise, we would not have been able to get such a great first home in this extremely competitive market. He is extremely knowledgeable, a great communicator and truly works to get you what you want. He always answered all of our calls, emails or texts as soon as he could. We will definitely use Mark again in the future for any real estate needs. If you are looking to buy or sell, I HIGHLY recommend you reach out to him!

Mark Ruby is simply the best you will ever experience. We had some upgrades to complete in a short time period as the market began showing signs of changes. Marks experience kicked in and connected with a wonder of network people who were the best at what they do. The house sold quickly and to an appreciating buyer. Mark is not your average agent, simply the best, you WILL NOT be dissapointed. Thank you for all you did, can't say nought good things about you as a person and of course your hard work, Ernie Pepe

Working with Mark to sell our house was great. He had excellent advice for what work to do to get top dollar, and had local vendor connections which made getting that work done a breeze, and for a fair price. The house looked amazing with his staging and professional photos. We got multiple offers with only 2 days on the market! Working with Mark made a stressful moving situation super easy. He was professional and very communicative through the whole process, checking in frequently. Could not recommend him enough.

Mark was absolutely phenomenal from start to finish throughout the home buying process. This is my first home ever and I felt incredibly supported and cared for every step of the way. He always made himself available to chat, go to open-houses, and answer any questions I had. He genuinely wants his clients to find their perfect fit and has your back the entire time. He opened every window, flushed every toilet, examined every roof, looked at every appliance, etc. to make sure the home was in top shape. He is extremely knowledgeable and will help you put in a competitive offer that remains in your best interest. Fantastic guidance and professionalism all the way through. So happy and honored to work with him, cannot recommend enough!!

Mark made the sad task of selling my dad's house (also my childhood home) in Westminster seamless and easy. I was nervous about the process since I live in Ohio and had no local family presence to help, but Mark stepped into the gap with professionalism, grace, efficiency, and kindness. He was always available, gave me great references for work that needed to be done on the house, and facilitated a quick and smooth sale. He truly went above and beyond, and I am tremendously grateful. I absolutely recommend Mark to anyone buying or selling a home in the area - he's amazing!!

Mark Ruby is a phenomenal Real Estate Agent!! He helped my mother and I get our house sold! It all began when Mark came into the house to guide us through decluttering to prepare for showings, Once the professional photos were ready to put on line the day it was listed, the showings began!!
The incredible job that Mark did to assure that adequate showings were properly scheduled helped to make the process flow extremely well as people made appointments to come view the house.
When we received notice that a buyer wanted to buy the house, we were excited!! Mark was there to cheer us on and the celebration began!
Settlement day went extremely smooth as Mark was again right there with us! His professionalism and knowledge of craft for real estate has a positive/effective impact that makes him automatically successful!!
MARK RUBY IS CERTAINLY WITHOUT QUESTION, A 5 STAR REAL EASTATE AGENT!! I RECOMMEND HIM TO ANYONE THAT IS LOOKING TO SELL OR PURCHASE A HOME!! KEEP UP THE GOOD WORK MARK!! YOUR REPUTATION IS AWESOME AND WELL DESERVED!!
THANK YOU MARK FOR EVERYTHING DURING THIS INCREDIBLE EXPERIENCE IN WORKING WITH YOU TO SELL OUR HOUSE AND TO BUY THE NEW HOUSE RIGHT NEXT DOOR!!! YOU ARE APPRECIATED!!

Mark is an outstanding real estate agent and we couldn't be more pleased with our end result. After our initial meeting at our home in Catonsville, Mark gave us good recommendations on how to stage our home to draw in potential buyers. He performed a comprehensive analysis of home prices in our neighborhood and we agreed to a good and fair price that he thought would sell the home quickly. Mark was able to spread the word about the upcoming listing via a wide media network he utilizes that includes his real estate peers. The first day the home came on the market, 17 real estate agents and their clients toured the house. There were so many people around that several of our neighbors thought that there was a parade on our street and they came out of their homes to observe. There were people in the front yard, in the back yard, in the house, and a line of cars with people waiting their turn. The same thing happened the next day when 13 more real estate agents and their clients toured the house. We received multiple offers on the house and based on Mark's solid negotiating skills he was able to get us an all cash deal, with a nice bump up above the asking price, and the house was sold as is without a home inspection. If anyone is looking for a top notch real estate agent, Mark Ruby is the man for you.

We were introduced to Mark by a close friend. I told Mark on the phone the first time we met that we were not great clients because we didn’t have a loan and weren’t committed to buying and we didn’t want to waste his time. He assured me that there would be no waste of time and he made an appointment for us to see our home that night for the next day. We saw the home the next day and loved it. Mark helped us get pre approved, make an offer, and get it accepted within 28 hours. Mark’s communication style is direct and honest, which my wife and I appreciated so much. He helped us process the type of offer to make and helped us prepare our home for sale. He helped with color choices, staging, and went above and beyond what I’ve experienced in the past with realtors. Mark also did a great job dealing with the emotions of insecure buyers and was always available to answer that panicky call as the emotions of buying and selling ebbed and flowed. Overall, Mark was just what my wife and I needed to help us make a very difficult decision to leave a home we loved to move into a home we can love into the future. I would not hesitate to recommend him to anyone. Fast, responsive, considerate, and knows the business of home buying and selling. He also had a great demeanor with the selling and buying agent which meant dealing with issues and potential stumbling blocks was extremely easy because of the relationship he fostered with the other realtors. Go with Mark, I’m positive you won’t regret it.

Mark is an excellent realtor and I highly recommend him. I’ve worked with multiple realtors and Mark is the best. Mark will get you the best offer and then guide everyone through the closing process smoothly. We had a few challenges come up from the buyer in our last transaction, but mark kept us all on the same page and made sure we were able to close. Also an expert at pricing and strategically making changes to give your house the best chance to sell.
