Of Knapton’s property in Cambridge, nothing is known save for his house, called ‘Bolton’s’ or ‘Knapton’s Place’ in Trumpington Street.
Early in his career, Knapton had been bailiff for two years running, but he then held no borough office again until, in 1432, the year after his last return to Parliament, he became mayor. However, in the interim he was not uninterested in local affairs, because in addition to his service as a parliamentary burgess on four occasions (at well spaced intervals) he also acted as a witness to the electoral indentures of return (doing so in May 1413, April and November 1414, 1417 and May 1421). Furthermore, in April 1426, at a meeting in the guildhall, he was nominated by the mayor and assessors to choose, with Richard Bush, the first eight members of the common council. He himself became one of the 24 councillors, and later in the year he was named among the aldermen who represented the town at the Magna Congregatio of the university.
