A Delta Psi historian later claimed the withdrawal was due to the expenses the fraternity was incurring sending delegates to the meetings of the Anti-Secret Confederation.

[8] Delta Psi did not become a residential fraternity until 1903 when it acquired its first house with the assistance of its aging founding father, Goodrich, by then a professor of Latin at the university.

[10][11] Delta Psi's new facility was a magnificent Queen Anne structure built in 1892 by Burlington businessman Edward Wells.

[12][11] During the 83 years of Delta Psi's occupancy of the Wells Mansion it became famous for the 100-keg Oktoberfest parties the fraternity would host.
