[2] Having put by a considerable sum of money, Tattersall purchased in 1766 from the Earl of Grosvenor the ninety-nine years' lease of premises at Hyde Park Corner (then an outlying part of London).

[2] In 1774, Tattersall sold the stud of his former patron, the Duke of Kingston-upon-Hull, and had some difficulty in resisting the claims to the proceeds of the rapacious Elizabeth Chudleigh, Duchess of Kingston.

Early in 1779 he bought the famous racer Highflyer from Lord Bolingbroke for what was deemed the enormous price of £2,500, being then described as "Richard Tattersall of the parish of St. George-in-the-Fields, liberty of Westminster, gentleman.

[2] Tattersall purchased New Barns, near Ely, known thenceforth as Highflyer Hall, where he regaled chosen spirits, such as the Prince of Wales (afterwards George IV), Charles James Fox and William Windham, with "some of the best port in England."

About 1788 Tattersall became proprietor of the Morning Post, which, in spite of the clever verses of Peter Pindar (John Wolcot) and the attention paid to sporting matters, proved a losing venture.
