Flipping houses is back in vogue, interest rates are low, and property values are appreciating faster than they have in years.

Today's real estate market rekindles memories of the last decade's housing bubble.

According to a national survey released this month, people have grown increasingly concerned about the state of today's housing market: Fifty-eight percent of the nearly 1,100 people surveyed in July say they expect there will be a "housing bubble and a price correction" in the next two years – a 12 percentage point increase since April.

Already, the survey found, such unease has produced a pool of buyers who are more wary about purchasing homes than they once were. Sixty-three percent of all home buyers and 72 percent of millennials say they worry about timing the market accurately and want to ensure that they are not "buying high." Even more, 80 percent of homeowners surveyed reported that they think now is a good time to sell.
