Tina, I have sold homes on 10th Ave and the values vary as some are 10000 sq ft and others are 1500 sq ft.
The area itself is a residential area with great walkability. A new restaurant just opened nearby and Historic Bethlehem is also near.
To really help you ascertain value, the house [ size etc] the neighborhood and the condition need to be reviewed. So please call me with more info and perhaps we can reach some idea of what you need.
I wish you luck and hope you get to enjoy the lovely tree lined streets of this area.
