De Vere spent most of his life on the estate and was closely involved in its management.
He suffered much trouble from his ownership of the island of Lundy, which his father, who was not much of a businessman, had unwisely purchased in 1802, and which became a heavy drain on the family's finances.
Sir Vere was never able to find a purchaser for Lundy, and it took his son until 1834 to dispose of it.
Sir Aubrey stood for election in the 1820 General Election and came in third with 2921 votes.

He fell out of favour with the Queen in the early 1580s and was exiled from court after impregnating one of her maids of honour, Anne Vavasour, which instigated violent street brawls between de Vere's retainers and her uncles.
De Vere was reconciled to the Queen in 1583, but all opportunities for advancement had been lost.
In 1586, the Queen granted de Vere a £1,000 annuity to relieve his financial distress caused by his extravagance and selling off his income-producing lands for ready money.

He died in 1604, having spent the entirety of his inherited estates.
