He was reelected for another year term as a deputy of the General Court in 1643. In 1644 Rice and two other Sudbury residents (Peter Noyes and Thomas Mayhew) were appointed to survey the farm properties of the estate of the deceased Joseph Glover near the southeastern boundary of Sudbury to be transferred to Harvard College President Henry Dunster who had married Glover's widow Elizabeth and assumed responsibility for the Glover children. On 18 June 1645, Rice and his colleagues reported to the General Court on their survey. In 1648, Rice was ordained as a Deacon in the Puritan Church at Sudbury. He was appointed by the General Court on 22 May 1651 as a member of a commission to settle a boundary dispute between Watertown and Sudbury, and he was reelected as a deputy of the General Court in each of the three years from 1652 through 1654. Again in May 1656, Rice and Peter Noyes were called upon by the General Court for their expertise to survey of land purchased by John Stone of Sudbury from the Indians, which was supplemented by a grant of the General Court to Stone of an additional in what is now Framingham. Stone erected a gristmill on his property of Stone's End in 1656 that would later become the village of Saxonville. And again in 1662 at the behest of the General Court, Rice and John Howe of Marlborough were called upon to survey of land in the area now known as Framingham that they deemed to be worth £10 to be awarded by the General Court to Thomas Danforth as compensation for his services to the Colony and Harvard College. Edmund Rice was particularly successful in his own real estate transactions. After selling his of land and homestead near the Sudbury meetinghouse on 1 September 1642 to John Moore, Rice established his residence on 13 September 1642 on his 20 acres of land abutting Henry Dunster's farm near the Old Connecticut Path in southeastern Sudbury. Within a year, Philemon Whale and Thomas Axtell, former town mates and kin from Berkhamstead, England established their homesteads on adjacent lots nearby. In October 1643 Rice sold Philemon Whale of land and a house near the Old Connecticut Path in southern Sudbury and also that same month he sold of adjacent land to Thomas Axtell. But only three years later on 6 May 1646, Rice, along with his son Edward Rice and Philemon Whale, administered the estate of the deceased Thomas Axtell and he purchased back the land from the estate shortly thereafter.
