When my siblings and I sold my late parent’s home, we used a realtor that we had known since high school (40 yrs). She was just about to retire but agreed to help us with the sale. She was worth every dime we paid her at closing. She weeded out non-serious buyers, let us know things that needed to be done to increase the sale price, and found us a septic guy at the last minute to repair and certify the septic tank (for minimal costs). She got us through the check-list and kept us from panicking. Also, the photographer she used for the pictures was fantastic.
We sold the property to a young couple with a 6 month old son. They had been looking for the perfect place for their needs for almost a year and our place fit the bill. I think my folks would like them as they would remind my parents of themselves when they were young and just starting out. It’s a bit of a fixer-upper but a solid home overall and they are enjoying the place. The wife occasionally texts me with questions and even invited me to come pick blueberries after the sale.
