Condo prices in Rhode Island are down, sales are up, and the number of units on the market continues to climb, according to real-estate reports released this week.

The statewide median price of a condo during the second quarter fell nearly 6 percent, to $222,000, according to the Rhode Island Association of Realtors. A separate report by a Boston real-estate research firm, The Warren Group, which also tracks sales by owners, reported the median price fell 4 percent, to $225,925.

Condos are also taking longer to sell. During April, May and June, the average selling time for condos in the state rose nearly 29 percent, to 98 days, up from 76 days during the same three-month period last year, the association reported. In 2005, the average selling time during the second-quarter was 62 days.

At the current pace of sales, it would take about 8 months to sell all the condos on the market at the end of June, up from 6.6 months during June of last year, said Suzanne E. Mulvee, senior real-estate economist with Property & Portfolio Research, in Boston.

In Massachusetts, the supply of unsold condos in June fell to about 7 months, down from 8.7 months in June of last year, according to the Massachusetts Association of Realtors. However, the volume of condo sales in the Bay State also was down, suggesting that sellers may have decided to take units off the market, Mulvee said, “rather than to let them sit.”

In Rhode Island, the pace of sales quickened during the second quarter, which is good news, said the Rhode Island Association of Realtors’ president, Cecile Cohen. The number of condo sales during the second quarter rose 5.37 percent from the same period last year, the association reported. The Warren Group reported that condo sales during the second quarter rose 8.4 percent, but less than 3 percent over the first six months of the year.

Whether the pace of sales in Rhode Island is rising fast enough to move all of the new condos coming onto the market, however, remains unclear. The number of condos for sale at the end of June rose 8 percent, to 1,926 units, compared with 1,784 units in June of last year, the association reported. But that is just one month. The association was unable this week to provide historical comparison data for June, said a spokeswoman, Kerry Park.

Last May, statewide condo listings were up 21 percent from a year earlier — and more than 140 percent since 2005.

Higher inventory levels generally tend to put downward pressure on prices — and that could partly explain why condo prices in the state have dipped. The median price also can fluctuate depending on the mix of properties being sold.

In Woonsocket, for example, condo sales were up but prices were down sharply. The number of condo units sold during the second quarter more than doubled, to 29 units, from 11 units sold during the same period last year, but the median sales price fell 16.75 percent, to $181,900, the association reported.

On the more affluent East Side of Providence, the median condo price during the second quarter fell 8.12 percent, to $249,000, compared with $271,000 during the same period last year, the association reported. (The association tracks sales by real-estate agents.

“The condo market is taking definitely a longer time” to come back, said Suzie Prescott, a real-estate agent at Coleman Realtors on Providence’s East Side. “The high-end condos … are not rolling out the door as quickly as developers had wanted…. The lower-end condos seem to be selling.”

Meanwhile, in Warwick, the median condo price during the second quarter rose 12.16 percent, to $207,500, from a year earlier, the association reported.

During the first six months of this year, the median condo price of all condos sold (including those sold by owners) fell 4.3 percent in Rhode Island and 3.6 percent in Massachusetts, according to The Warren Group.

Construction of new houses has also declined. Permits for new houses in Rhode Island fell 6 percent during the first six months of this year from the same period last year, according to the Rhode Island Association of Builders.

Mulvee, the economist at Property & Portfolio Research, said that far more worrisome than the market softness due to rising inventory is “what’s going on in the debt markets and how that’s going to affect residential lending.” If home foreclosures continue to rise and lenders keep tightening credit standards, it could sharply reduce demand for houses, and “you could really see a much sharper downturn, and more prolonged.”
