President Barack Obama has said an over-supply of homes is hindering the US economic recovery.
Mr Obama also said the US had to find a way to curb its budget deficit without further slowing economic growth.
"People, consumers, are not going to start spending until they feel a little more confident that the economy's getting stronger," he said in Ohio.
Mr Obama is touting Democratic policies on a campaign-style swing through important electoral states.
The president told a group of about 30 voters at a private home in the city Columbus that a glut in the housing market was partly responsible for the slow economic recovery.
"The housing market is still a big drag on the economy as a whole," he said.
"It is going to take some time for us to absorb this inventory, that was really too high... We were building 2 million homes a year when only 1.4 were being absorbed."
Mr Obama was speaking at an event the White House billed as a "kitchen table and backyard discussion".
The economy is expected to be the single biggest issue for US voters in November's mid-term elections.
Unemployment in the country is lingering at around 10%, and US growth slowed in the second quarter of 2010, sparking fears the country might fall back into recession.
