  • Evan Flamm

    Margaux was professional and a pleasure to work with. She had a good pulse on the market and moved quickly on an offer, which was one of my requirements with a realtor. She helped me land a great condo in the city and couldn't be happier with the place. I highly recommend her to others in Philadelphia looking for a positive home purchasing experience.  

  • Mark Rutledge

    Our experience with Mary and Margaux was excellent from the first phone call right through the settlement meeting. We were looking for an agent that was professional and savvy, and one that we could trust. We wanted an agent that would provide an honest, fact-based, and realistic recommendation on pricing our home - not an artificially high price to entice us that would do more harm than good to the marketability of our home, but a price that would maximize our return. On-line reviews led us to Mary and Margaux and we're glad we found them. They make a powerful team - knowing how to combine their unique skills in an efficient and complementary way. They are honest and professional - they earned our trust quickly. They are experienced - which means they are confident and composed at the critical times in the selling process. They were open to listening to our ideas on the key selling points of our property and to our desired level of communication. They have a very strong team, with a special call-out to Scott. After seeing Scott conduct an open house for us, it was clear he is also a top-notch agent. Overall, a very solid experience leading to a successful result. We would highly recommend you consider the selling team of Mary and Margaux

  • John & Elizabeth Hanks

    "My husband and I were in a unique position as long term renters who suddenly needed to find our first "starter house" that would satisfy our family of four and two dogs.. in the good school district but at a great price. Margaux was able to successfully navigate us through the processes and advise us at each step of the way. We were all over the map in terms of what we wanted and she expertly guided us and provided advice while somehow listening to everything we said. It was clear to us that not only was she knowledgeable but she had her pulse on what was happening in the market. When Margaux said that the house was overpriced, we trusted her, when she said to bid our max, we complied. The market was tough and the process took longer than we expected but Margaux never slowed down and continued to curate great possibilities. Again, as a picky first time home buyer I couldn't imagine having anyone else by our side. I can't say enough about Margaux and would recommend her to anyone, no exceptions."

  • Diane Bartoli

    We chose to list our home with Margaux based on her deep knowledge not just of Center City but our neighborhood within it. We were relocating across country, so time was a premium for us, but we wanted to get as much as we possible could. She did an excellent job of marketing the property, from ensuring it was listed everywhere it needed to be online, to working her own network buyers agents, to listing it at exactly the right price. We had an offer the same day it went on the market, and 3 the evening of the open house. We were in contract within 3 days of it going on the market, at a price above our asking price. I would recommend Margaux wholeheartedly -- she was an absolute pleasure to work with!

  • Jamie Froehlich & Meredith Miller

    Margaux made our first home purchase in Philadelphia a breeze. Never pushy, always straight forward and honest, super responsive, and truly a joy to work with. What we though would be a couple month search process quickly turned into the better part of a year and Margaux never lost sight of our interests/requests, kept us patient, and helped us get exactly what we were looking for. From our first consult, all the way to closing day, it was clear we were in the best hands. Looking forward to working with Margaux again in the future for any of our other real estate needs!!

  • Gina & Daniel Criscitelli

    Margaux was exceptional in listening to our needs and pointing us in the right direction. Instead of ushering us around to every house in existence, she brought us to the houses she knew we would love. And she was right! We ended up purchasing the third home we saw, and couldn't be happier!  

  • Katie Grossman & Ed O’Reilly

    Margaux was incredible to work with in our housing search! She is the absolute best and I highly recommend her to anyone looking to purchase a home in Philadelphia. She was extremely patient and listened to all of our wants & needs to ensure we found the best property for us in our price range. Her insights were so incredible that she found us the perfect home that we would never have found ourselves. I can't thank Margaux enough and look forward to hopefully working with her again in the future!

  • Rinad S. Beidas

    Margaux Pelegrin is the embodiment of what all realtors should strive to be like - we will never work with anyone but Margaux going forward for any home sales or purchases. We worked with her for over 9 months to find the perfect home in Philadelphia. She was patient, incredibly knowledgeable, supportive, and was available 24/7. Her team is also fabulous. Margaux has tremendous expertise in the Philadelphia market, having grown up in Philadelphia, and she takes tremendous pride in her work. We couldn't recommend her more highly - she is truly a spectacular star!

  • Steve & Leslie Levick

    On our property, Mary and Margaux brought us realistic prospective buyers and in a consistent manner. They worked with us on timing of appointments and in getting house ready. Bids were all represented in the ballpark we asked for. After contract they helped us find contractors to complete necessary repairs.  

  • Adam Stump

    We cannot imagine a better realtor existing than Margaux. She was extremely knowledgeable and always quick to reply when we had questions, which there were many of, as we purchased our first home. We had high expectations for our budget and Margaux showed us numerous options which met our criteria. She was wonderful through the entire process and if we ever decide to move she is the only person we will call."

  • Frank Donaghue, CEO, Friends of the Orphans

    I have bought and sold more than 6 homes in Rittenhouse Square. It wasn’t until my last few transactions when I met Mary and Margaux did I understand that I was now dealing with the best. They define customer service and professionalism. I laugh at the ads that say, “we sell the most, or largest number of condo sales”. When I am buying or selling my most significant possession, my home, I want the best, the most professional, someone that treats my property and my needs as their own. I want Mary and Margaux. Someone that sells the most in no way means they serve the seller or the buyer the best. What I learned from Mary and Margaux is that I was not just one more appointment in a busy schedule. They really cared about what I wanted; they listened very carefully to my needs. I never felt like I was being pushed into a deal I didn’t feel right about. I certainly never felt it was just about getting the sale or the deal done. With Mary and Margaux it is all about a relationship that is why so many of their clients are still both clients and friends for life.

  • Moniica McKay

    "Margaux was phenomenal, no matter how big or small the issue she was always willing and able to help. We priced right based on her recommendation, got above ask, and had very little anxiety through the process. I would, without question, use her again; top marks!"

  • Catherine Moellering

    There are not enough superlatives to sufficiently describe my experience with Margaux Pelegrin. She is a consummate professional and possesses both the IQ (local knowledge, financial acumen, etc.) and the EQ (consideration, patience, etc.) necessary to create an exceptional real estate experience. Most importantly, she found my dream home and negotiated a great price!

  • Bria McMenamin

    “Margaux was the Realtor for my first home purchase and I am so grateful for her as she made it such a wonderful experience. Having lived and worked in the city her entire life, she has tremendous insight into the Philadelphia market, a great network of relationships and also a very keen sense of ability to read her clients. She introduced me to properties and areas I wasn't even aware that I wanted and yet I instantly fell in love with most of her suggestions. Margaux responded immediately to all of my emails, which I was sending so many that I was starting to annoy myself, and most importantly, she helped me to negotiate a price that not only secured my dream spot but also was within my budget. Plus, I really enjoyed hanging out with her as we visited and traveled to all of the sites; she has a great personality. I highly recommend her.”

  • Nicholas Wolk

    "Margaux was such a pleasure to work with. Super responsive and available! Her knowledge of the local real estate market was invaluable in helping us to sell our home quickly and find and secure our new dream home in a very competitive market. I would 100% work with her again and recommend her enthusiastically to anyone I can!"

  • Sarah Pierce

    "I could not recommend a professional more highly than I recommend Margaux. Buying a (very expensive) home is stressful, nerve-wracking and an altogether new experience. We bought our home in Fitler Square in an extremely competitive market for buyers. Margaux had great insight into what would be coming up for market (which was crucial in this market -- she truly, truly knows the market in Center City); on-point instincts about when to make an offer, and at what price point; when to walk away and wait for another house. We were the winning bidder in a competitive bidding war with Margaux's excellent guidance. When it came time to inspect, and then close, she held our hand throughout the process. It was truly seamless and low stress. She was ethical and above board at all times. She went beyond just getting us the house and closing--recommending contractors, landscapers, roofers, and the many other professionals we needed to make our home our own. I recommend her to friends and family without hesitation. She will get you the house you have been waiting for, or sell your house at top price. She is smart, confident, knowledgeable, and honest. You can't ask for more than that."

  • Lauren Daniels and Greg Schernecke

    “Margaux is a life-long center city resident who knows the ins and outs of the city. She is incredibly knowledgeable about the inventory and resale value when looking for places and she will help stage your home to make sure you get the best offers possible. Margaux is very responsive and always quick to offer helpful referrals and suggestions of how to make the best of your home.”

  • James Colleran, ESQ. – The Colleran Firm

    My wife and I contacted Mary and made known to her what we were looking for. She saved our time by directing us to properties we liked and considered buying. In a short time, Mary found exactly what we were seeking and we bought our residence. Margaux was very involved in the entire process and gave us helpful referrals to contractors for modifications we wanted to make. Both Mary and Margaux know the market, are very professional, have good common sense and looked out for our interests. Our experience with them was refreshingly positive.

  • Eric Gromball & Amanda Nitti

    “Margaux helped my husband and I purchase our first home this year. She is incredibly knowledgeable about the Philadelphia market and neighborhoods. She was easy to get in touch with, flexible, and made us feel comfortable throughout the entire process. She's very honest which was exactly what we needed as first time buyers. We would recommend her to anyone!”

  • Paige Jaffe

    Mary and Margaux have now represented us in multiple transactions. They have helped us sell and purchase two homes. Mary and Margaux are always very professional and honest. They will go above and beyond to make the process seamless. They both know the city of Philadelphia like the back of their hand and can provide detailed information at all times.

  • Erika Bohman

    Margaux was a fantastic agent. She was knowledgeable, responsive, and a skilled negotiator. My house in Fitler Square was under contract in 48 hours thanks her excellent marketing and pricing strategy. She also didn't make me go crazy with staging, which I really appreciated because I have two small children.

  • Danielle Muirhead

    I wanted to purchase a home quickly in early 2013. I met with Margaux within a couple of days of reaching out to her, toured homes within a week and was under contract within another week or so. The process could not have gone more smoothly for me. Margaux was great to work with! She was responsive and very knowledgable and has excellent customer service skills. I would highly recommend her.

  • Megan J. Brody

    We used Margaux as our realtor to buy and sell two houses, and all of our experiences with her have been fantastic. She is extremely knowledgeable about the Philadelphia center city housing market, she does a great job marketing her properties, and she is a true advocate for her clients. Both of the homes that we sold with Margaux were sold within 30 days for very good prices. When looking for a new home she listened to our needs and found us beautiful places. I would HIGHLY recommend using Margaux to either buy or sell your home.

  • Kelly Tomer

    My fiancé and I worked with Margaux to buy our first home in Philadelphia, and we could not have asked for a better experience with a realtor! As first time home buyers, we needed a lot of guidance, and she went above and beyond to help us every step of the way. She was very patient with us as we figured out exactly what we wanted from neighborhood to house size. Her knowledge about the market and neighborhoods in Philly helped us find a home that we love! We have already recommended her to friends looking for a home, and they are closing on their dream home next weekend! If you want a realtor you can really trust, call Margaux!    

  • Mick Merritt Jr. & Dale He

    "I can't say enough positive things about Mary and Margaux. They provided so much valuable advice every step in the process. They also have a network of great referrals for services and professionals that was so helpful for a family who recently moved to Philly."

  • Krysta Genovese & Bradley Jones

        Margaux helped my fiance and I find the perfect first home! Going into it, we had no idea what to expect or what we were even doing, ha! Margaux not only walked us through each step of the process, but also showed us some amazing properties until we found THE ONE. She was on our side the entire time, by hard negotiating with the sellers and making sure the property was perfect for settlement. Our experience was really fun and in the end we got everything we wanted.    

  • Dana Shanis

    Margaux was great! My fiance and I were originally considering only houses in Graduate Hospital, but Margaux suggested we also see some houses in Fairmount and we ended up loving it. She listened well to what was most important to us and refined listings each time we went out to look with her. After finding a new construction, she recommended several upgrades and helped us negotiate to a wonderful final product. Now we love our home, and could not have done it without Margaux!

  • Jennifer & Andrew Eimer

    “Margaux is a true professional and wonderful at her job. She makes the process very easy and enjoyable. Margaux sold our condo in just 2 days! We couldn't have asked for an easier experience.”

  • Kait Falconer

    Margaux was both professional and approachable. This made us feel extremely comfortable expressing our expectations and also any doubts that would arise during the search process. It was clear she had our best interest at heart and she did a great job getting us our dream house within our particular means. She was also really quick to gain an understanding of our vision and was able to hone in on our specific tastes, making the process a lot easier and less time consuming. A pleasure to work with, and a refreshing break from the ego-centric agents that are so prevalent in the real estate world!

  • Zachary McClain

    Margaux is tremendous. She is incredibly knowledgeable about neighborhoods, housing specifications, and changes and renovations that can be done to a home--she shares this information freely as you are touring a home. I saw a home with her on a Friday morning and we had an offer signed that night! Her efficiency is unparalleled. She was easily reachable via phone, email, and text messaging. She responded to our (many!) questions (first time home buyers!) almost instantly--including weekends. I couldn't give any higher praise for Margaux. She is now my Philadelphia realtor for life!

  • Lauren & Fernando Bairos

    “My husband and I have worked with Margaux twice now, once as first-time home buyers, the second when we sold our house four years later. We moved to Philadelphia from out of state and were very unfamiliar with the city at the time we were looking to buy. Margaux worked with us for several months, showing us various properties all over the city and helping us narrow down our preferred areas. She is an incredibly diligent and thoughtful realtor and always had our best interest in mind throughout the often stressful and tedious process. We ending up buying the perfect house in a neighborhood that we absolutely loved, and when the time came to sell our house, there was no question we would use Margaux's services again. I cannot stress enough the amount of professionalism and expertise she brings to her work. She is an incredibly skilled negotiator as well, and we knew she would go to bat for us when the situation called for it. As a bonus, she was born and raised in Philadelphia, and knows the city better than anyone else I've met.”

  • Kathleen Wickman Epstein, President and CEO, Medtelligence, LLC

    Searching for and purchasing a new home should be an enjoyable and exciting experience. All too often it comes with frustration and disappointment. Mary and Margaux are true professionals, always researching the right properties and never wasting your valuable time looking at properties that aren’t on your target list. The comprehensive and personalized work of this team is something that potential Philadelphia home buyers and renters should experience first-hand.

  • Frederick Morlok

    It's very easy to write about a successful transaction. What I look for in an agent is knowledge of the marketplace, pricing based on competitive factors, and the use of latest technology to appeal to a wide audience. Mary and Margaux have competence in all three. I also appreciated the help in filling out the complex local and state forms. The transaction was completed with no need for a real estate attorney. Mary and Margaux don't let issues "sit". They respond with quickness and accuracy. I have used Mary and Margaux for buying, selling, and rental. Who could ask for anything more?
