OK, when Realtors start talking about the market reaching a “tipping point,” it can only be bad news for buyers worried about soaring prices.

It means things are starting to get a little crazy.

As we head into summer, sales activity is soaring, with buyers spooked by rising rates and the prospect of more price hikes ahead.

More than 9,000 homes across Massachusetts were put under agreement this May, an 83 percent jump from May 2012, the Massachusetts Association of Realtors reports.

Pending sales of condos rose more than 63 percent in May, to 3,469.

Both increases where the highest recorded since MAR began tracking pending sales in 2004.

Here’s what President Kimberly Allard-Moccia, president of the local Realtors group, had to say.

“May was a tipping point as increasing prices and interest rates pushed qualified buyers to make offers that sellers accepted in great numbers,’ said Allard-Moccia, broker-owner of Century 21 Professionals in Braintree, in a press statement.

“However, we still need more homes on the market and hopefully this activity will spark potential sellers to list their homes to help meet the demand,” she added.

Tipping point?
