The house had been abandoned for many years when it was purchased by the Pell family in 1936. The interior of the house has undergone extensive renovations a number of times but retains some original details including wood plank floors and fireplace molding. The lower level features the original rough-hewn exposed beams. Cornwell Farm is currently in use as a private, 4-bedroom residence. Before renovations, signatures of Union soldiers from a Civil War-era occupation were visible on the mansion's plaster walls.
Modern development at Cromwell Farm was altered by a local citizens' movement in 1972. As a result, the Yeonas Company developed the property's western 200 acres into residential properties more in line with the area's historic appearance. The historic house was preserved on a lot of about 13 acres and was listed on the National Register in April 1977.
The property was offered for sale in 2013 for nearly 5 million and includes a heated swimming pool, caretaker's cottage with attached greenhouse, four-stall horse barn, and pasture land. Not a bad rate of appreciation - the earliest insurance evaluation found for the home was $1,850.
