Lake is first recorded in 1381 when acting as a feoffee of the Exeter property of John Hill, the lawyer and future judge, and his own career as a lawyer was undoubtedly furthered by this connexion. In 1389 he assisted Hill to purchase the manor of Houndestone in Brimpton (Somerset), an estate forfeited by Sir John Cary, chief baron of the Exchequer; he later also acted as trustee of the Devonshire estates of Hill’s son Robert,
In 1391 Lake had acquired from the vicars-choral of the cathedral of Exeter a lease, for life and one year, of the church of Woodbury, about seven miles from the city. As he contracted to pay an annual rent of as much as £32, it is clear that the estate was of considerable value. In 1413 he had an interest in lands in ‘Nyweton Devenebury’ and ‘Exilond’, the reversion of which pertained to Sir Hugh Courtenay. His numerous properties in Exeter included the garden of a house in Gandy Street which had once belonged to Sir John Cary. In November 1421 it was his widow who paid the rent for their two shops and house next to All Saints’ church, so evidently he had died earlier that year.
