TeardownExcellent
Property is moderate renovation needed.
Built in 1953, the home features a kitchen and interior that appear to have been renovated approximately 15-25 years ago. While the property is well-maintained and move-in ready, it is dated by modern standards, and the listing description emphasizes development potential and 'building new,' suggesting the value lies primarily in the land and that systems are likely aged.
