Ratings & Reviews

Quentin M.

Sierra made my entire home buying experience a breeze and went out of her way to make sure everything went as smoothly as possible throughout the entire transaction. The first property I was interested in ended up going pending as she was showing it to me and knowing how sold I was on finding something in that area, she went out of her way to contact nearby property owners to see if there was anyone else interested in selling in that same area. She ended up finding the property I purchased from one of those calls she went out of her way to make and if it wasn't for her dedication, will to think outside of the box and determination, I would probably still be looking for my dream property. I was referred to Sierra by a family member who shared a similar story about their experience working with her on the sale of their properties. I will use her for everything in the future and would highly recommend her to anybody looking to buy or sell. Thank you for all that you did for me!
