If limited choices weren’t enough of a headache for California house hunters, rising prices have made the chore even more painful.

Last month’s California median selling price for a single-family home was $415,000, up 5.6 percent from March 2015, and now at the highest level since 2007, according to a PropertyRadar report. The condo median price was $400,000, up 3.9 percent in a year.

High costs and thin supply hurt sales activity, PropertyRadar said. Single-family home and condominium sales statewide in March were down 4.7 percent from a year ago in the second slowest-selling March since 2008.

“The lack of inventory and terrible affordability are a drag on sales. Without new inventory, sales will likely remain flat for the foreseeable future,” said analyst Madeline Schnapp of PropertyRadar. “Affordability and lack of inventory is a challenge in every part of the state with a decent job market. The closer you are to the coast, the worse it gets.”

The largest price jumps among the state’s largest counties were found in Santa Cruz (14.5 percent), Santa Clara (12.6 percent), Marin (11.5 percent), Contra Costa (9.5 percent), and Los Angeles (9.1 percent).

“As prices march steadily higher, they eventually hit a level where you run out of buyers willing to pay those prices,” said Schnapp said. “Are we there, yet? Probably not, but we are certainly getting closer!”
