Sold my home for top price

Karen Harms was excellent at listing my home. She sold it for the highest price in the community and was very knowledgeable with guiding us.

Karen did an excellent job for us

Karen did an excellent job for us. I believe she did more than we could have expected! She’s very knowledgeable about the whole process and explained everything step by step so we can understand it clearly! She really went above and beyond watching out for our best interests!! If you’re looking for a good realtor I highly recommend contacting Karen at Cummings!!!

Karen and the Harms group were great to work with! The knowledge and experience brought into the sea

Karen and the Harms group were great to work with! The knowledge and experience brought into the search for and negotiations of buying a new home were invaluable. Certainly filled in the gaps that I was unaware of and all with a professionalism and thoroughness that would be matched by few. I highly recommend to ensure you get the right info and the necessary help in making the best deal for the right house!

When my wife and I decided to move back to Maryland from California, we knew Karen would be the righ

When my wife and I decided to move back to Maryland from California, we knew Karen would be the right agent to help us handle the purchase of our new home. Karen helped us refine our search, parse through the results and find the perfect house. She met with us on short notice when we flew in for an on the ground search, and helped us negotiate a deal before our wheels took off for home. It couldn't have worked out better. Throughout the closing process she has been an invaluable advisor, and our eyes and ears in Maryland while we closed up our lives on the West Coast. We couldn't have done it without her. Needless to say, we highly recommend Karen!
