C. & R. Lewis

Petra Hartman was our realtor during the short sale of our 5.25-acre ranch. Petra was supportive and did everything to make sure the property was shown correctly, secure and advertised properly. Once our homes offer was accepted, Petra still did everything possible to make sure that the escrow and bank cooperated. Moving forward, Petra will be our realtor and I would recommend her services.

Petra Hartman did a great job in helping me sell my home in Hidden Valley Lake while I was living overseas. She provided me with a wealth of information and several potential options when we first discussed selling the home. She promptly visited the home, advertised it, contacted my mortgage lender, took care of all the required paperwork, and sold it for a price higher than expected. She was very professional and did a great job. I highly recommend her as a real estate agent.
