Sharon Castelli GRI, ABRAs you can see from reading her reviews Sharon Castelli gets lots of accolades and every one is deserved. Not only does Sharon provide information and insight at the right time and place, she goes above and beyond that -- staging a house, taking really good photographs, fixing a stuck window. Above that she is patient -- I am 74 years old and struggled some in the months-long process of getting rid of possessions and selling a big house; Sharon had infinite courtesy and great support. I [...]

Sharon Castelli GRI, ABR A few weeks ago I closed on selling my house thanks to the extraordinary service of my listing agent, Sharon Castelli. This was not my first time as either a buyer or a seller, but it was without question my best experience, bar none. We all know that there are a thousand curve balls that can derail the process once you get started, some of them can be self-induced by our own floundering and doubts. Selling or buying a home is a huge life decision for most of us. Having a kind, wise and [...]

Sharon Castelli GRI, ABRSharon represented us as buyers and we had a great experience with her. She helped brainstorm ideas to make our offer more attractive and ultimately I think she was a reason we ended up getting our home. The seller's agent complimented her on multiple occasions on the offer she put together for us. She is very kind, responsive, and a joy to work with. Thanks Sharon!

Sharon Castelli GRI, ABRSharon was prepared with market insights, had a clear vision, rolled up her sleeves to help stage the house, and took beautiful pictures. She was very easy to work with, went above and beyond to support the sale while I was out of state, and we ultimately received multiple offers with a successful sale in just a 2 month timeframe from consult to close. Highly recommend!

Her in-depth experience of the real-estate process - from helping us to formulate our housing expectations relative to the competitiveness of this [...]

Sharon Castelli GRI, ABRWorking with Sharron on the sale of the house was actually a pleasure. She is fun to work with and offered many helpful suggestions. She explained the selling process very well and kept us updated daily as things progressed. We wish we had another hose to sell just to work with Sharron again! Thank you Sharron!

Sharon Castelli GRI, ABRAs a first time land buyer, I really didn't know what the process would be like. Sharon's grounded demeanor and careful and prompt communication was such an asset! And because of her negotiation, we were able to settle on a price that was better than I could have anticipated. Our offer (unfortunately) happened to fall on a holiday; nevertheless, Sharon spent the whole day negotiating. I really appreciated that and felt it was above and beyond. Sharon was upfront about not having as much [...]

Sharon Castelli GRI, ABRMy husband was hesitant to work with a buyer's agent, but Sharon was a joy to work with and incredibly helpful. She walked us through the whole process of buying our house, making the whole experience so easy. We thank her for her time and energy. The process could have been so much more stressful. Where many realtors we have experienced have been pushing urgency and pressure, she treated us like a true professional with sensitivity to what we needed. Again, our thanks!
