Even though home prices are not increasing as rapidly as they have been, housing is still a good investment according to Blackstone (BX) CEO Steve Schwarzman. Per CNBC

"It's been coming back for quite some time," Schwarzman told CNBC from the Milken Institute conference in Los Angeles.

"The market continues to go up for the value of houses," Schwarzman said.

However, a recent Gallup report shows that Americans might not be as optimistic.

Currently, 69% of Americans say it is a good time to buy a house, down from an average 74% during the prior two years.

However, this level is similar to what Gallup measured from 2009-2012. Americans are still more positive about buying a house now than they were between 2006, when home values stopped rising and interest rates increased, and 2008, after the housing bubble.
