Notley Abbey possessed several pieces of land including Lower Winchendon (not acquired until around 1302), Chilton, Princes Risborough, and Stragglethorpe in Lincolnshire. These lands helped generate revenue, but the abbey's primary source of income came from tithes from appropriated churches. Traditionally, a secular vicar served an abbey's appropriated churches, but in 1258, Alexander IV granted Notley Abbey permission to serve their appropriated churches by their own canons in person. In 1461, Notley Abbey absorbed a small priory of Chetwood, thus considerably adding to its revenue sources.
