Mark was referred to us by a friend who had recently bought a home. We had certain requirements and Mark patiently showed us homes (let’s just say MANY homes) until we found the perfect one! He was very knowledgeable and we learned so much in the process. We highly recommend Mark!

Margaret and Mark are extremely knowledge of the local market of suburban Philadelphia. They were very patient throughout the time looking for a home and we never felt pressured. Their persistence is what lead is to finding the home we ultimately settled down in. we are extremely grateful that they helped us find our first home.

We had a wonderful experience with Mark & Margaret. From our initial meeting to the final negotiation, they payed careful attention to every detail. Margaret's expertise in staging our home, taking photographs and marketing our property contributed to multiple offers the first weekend and a bidding war as a result! We were very happy with Mark's responsiveness and thoroughness throughout the process. We would highly recommend them!

We had a wonderful experience working with Mark Bythrow. We really appreciated his friendly, laid-back approach, and at the same time we knew we could always count on him to be immediately available to either answer our questions or help us move forward with our house-buying process. We would not hesitate to recommend him as a realtor.
