The estate agent, which owns Slater, Hogg & Howison, reported income of £154.9 million for the three months to September 30 in its second interim management statement since its stock market return.
The company, which welcomed the Coalition's decision to bring forward stage two of the Help to Buy scheme, said it achieved a "healthy increase" in underlying operating margins across all divisions, including estate agency and lettings, over the quarter. Countrywide told investors it completed 18,102 house exchanges in quarter three, up 13% on the same period in 2012, and reported a 21% increase in retail properties under management to 53,069, versus quarter three last year.
It said it had arranged 16,411 mortgages in the three-month spell - a 25% rise on last year - and reported a 23% increase in new home sales in the nine months to September.
Chief executive Grenville Turner said the firm "expects the second half of 2013 to provide the foundation for a strong recovery in market volumes in 2014."
