Street number prior to 1925: 623 was 403 Walnut

There is no date of construction given for this home but it appears to be contemporary with the two homes to the north, 619 S. Walnut and 615 S. Walnut. The 623 address does appear in the 1925 city directory with Charles Merkel as the resident.

This home also has an address on W. Fourth St.: 504 W. Fourth St. which does not appear in the 1925 directory.
