Almost three quarters of Americans give homebuying the thumbs up. According to the Fannie Mae national housing survey, 70 percent of Americans believe it is a good time to buy a home, up from 64 percent in a survey conducted in January. The number is down from 83 percent from a survey conducted in 2003. Fannie Mae surveyed 3,400 adults from June to July. Although more liked the timing of the market, 33 percent said they would be more likely to rent than own when they move next.
