Just a year ago only one in five people expected property values to increase during the first half of 2009.
However, around three-quarters said they did not think it was any easier to get a mortgage now than it was three months ago.
Zoopla said renewed confidence in the housing market suggested the number of homes changing hands would soon increase.
Nicholas Leeming, commercial director of Zoopla.co.uk, said: "This time last year, confidence in the property market was at rock bottom and the outlook was bleak.
"But a year is a long time in the housing market and, whilst the recovery is still in its infancy, optimism is now back to levels not seen since the credit crunch began in 2007.
"The shortage of homes for sale has prevented any improvement in transaction levels over recent months, but with increased confidence amongst owners about putting their homes on the market to match the pent-up demand from buyers, we could see a welcome boost to the recovery of the housing market."
