In 1804, the estate was auctioned off. The lot included: one house, a yard, a barn, a stable, a sheep farm, girding wall, garden, 18 ha of cropland, 24 ha of wild and fallow land and 7.06 ha of meadowland. It was assessed as being worth 4,088 francs; its final sale price was 8,000 francs. The estate went to the old estate holder, Josef Matthias Maas, whose forebears had held the estate for 200 years. The family Maas lived on the estate until 1916. In 1922, Dr. August Cnyrim, a former notary, and his wife Marie "née" Hellwig acquired the estate as a retirement seat, and they had the estate run by tenants. The husband and wife were both buried in the estate chapel. In the 1960s, the whole estate but for this chapel was razed for housing development, even though the chapel and the manor house were under monumental protection. Even the chapel was threatened with downfall – albeit from disrepair, not by development – before the little church was restored with support from the state of Rhineland-Palatinate, the district, the "Ortsgemeinde" and private donors. The chapel still stands today at the entrance to the village as the only remaining trace of the estate of Oberwinkel.
