Home sales in Connecticut jumped in June, but prices declined, a real-estate research firm said Tuesday.

Warren Group said 2,799 single-family homes were sold in June, up nearly 6% since June 2013. The firm said the increase was the best since last August, when 2,897 homes were sold.

Home prices, however, fell 3.2% from June 2013. The median sales price of a single-family home statewide decreased to $276,000 from $285,000 in June 2013.

Second-quarter sales fell by about 5%, with 6,679 sales, compared with 7,020 in the second quarter of 2013.
