We loved working with Penny, she is a very good Real Estate Agent. Since our first interaction with her we loved that she was transparent, honest and very knowledgeable. She guided us through the process of buying a new home and selling our old home, it all happened miraculously in a 6 week span. We closed both homes on the same day and moved in on that date as well. Penny was great and always available, she was on target for our selling home's price and a good negotiator for the new home. Her team is amazing (lawyer, broker, stager and photographer), thanks to this team it all went smoothly. With her selling strategy she drove 40 walking groups during a weekend open house and a couple of days of showings. We are grateful to Penny for her work, we recommend her and would work with her again.

Penny was outstanding to work with! As a first time home buyer she guided us through the buying process and ensured we were educated on all fronts before committing to signing. She was kind and knowledgeable and I am so grateful to have worked with her to find our dream home. Thank you so much Penny! ☺️
