"Sandra Tanco knows her stuff . Sheās a hard worker, follows through, making the buying experience seamless. Her knowledge of the area, and contacts in guiding us since we lived out of state, far exceeded our expectations. Sheās great to work with, from returning calls, or following up with a text, sheās always involved. I wouldnāt use anyone else! Thanks Sandra!"

"Sandra Tanco guided us through over 4 months of ups and downs including having to put in an engineered septic system within the time limits of our closing date. Sandra always interacted with us in an up beat and very positive manner that lifted our spirits when it looked like we would never close. Obviously, our experience with her on these two troubling setbacks as well as several other less serious problems was terrific! Hopefully I have been able to clearly express our complete satisfaction and good fortune to have Sandra Tanco as our real estate agent. Together we made a great team!!!" - Frank

"Sandra was professional and helpful throughout the entire two year process ; from previewing properties, to finally finding the right home for us, and closing our transaction- she was always responsive and went above and beyond to assist us with finding our Cape place. Sandra came highly recommended by a friend who has worked with her for years. So glad we took his advice to call Sandra!" - Terry

"My home was not a "cookie cutter" type of property, a point that Sandy Tanco and I agreed on from the start. It consisted of a house with three outbuildings situated on large lot on a busy road. Sandy marketed the heck out of the property trying to find the right client, showing the the property over a dozen times while the property was listed. Throughout the process, Sandy remained totally positive and never tried to goad me into reducing the price or accepting low-ball offers. In the end she found that ideal buyer and at a price very close to what we were asking. She helped in every phase of the sale from suggesting pre-sale improvements to helping us with the inspection and legal processes. I've bought and sold many homes over the years and have worked with many different realtors as a professional photographer. Sandy Tanco is the very best realtor that I have ever encountered--bar none! She was a joy to work with and a wonderful person as well!"
