As confidence in the economy grows, so do the number of potential home buyers that say they're ready to enter the housing market. According to a new survey from PulteGroup, one of the nation's largest homebuilders, 74 percent of Americans say the economy has remained steady or improved in the last year and 57 percent think now is a good or excellent time to purchase items they need or want. And buying a home ranks high on the list of things Americans want. Among respondents, 67 percent said they plan to purchase a home in the future with 32 percent looking to buy within the next two years. Margaret Gramann, senior vice president of sales for PulteGroup, said Americans have a growing sense of optimism that the housing market is improving and that these positive changes may be sustainable. And that growing sense of optimism has boosted their interest in buying a home, with 41 percent of respondents indicating that their interest has increased over the past year. Needing more space and the view that owning a home is a smart financial investment were the top two reasons cited by participants as spurring their interest in buying a home.
