Less than half of homeowners – 49 percent – currently believe their home is worth more than the amount they still owe on their mortgage.

July marks the second month in a row but only the third time since late 2008 that the Rasmussen Reports rate has fallen below 50 percent.

High-income homeowners were more confident in their home values that low-income homeowners, and investors were consistently more confident than owner-occupants.

One-third of homeowners believe they are underwater with their mortgage, and 18 percent of respondents said they weren’t sure.

The rates are the result of a Rasmussen Reports national telephone survey of 676 homeowners. The survey was conducted July 17 and 18, and results were released Thursday.

Relatively unchanged since last month, 7 percent of homeowners had missed or been late on at least one mortgage payment in the last six months, while 90 percent had not.

Eight percent said they were likely to miss or be late on a payment in the next six months, and 89 percent did not foresee difficulty making their payments over the next six months.

Just days before the survey results, on July 19, Rasmussen released the results of another survey, which examined homeowners’ confidence that their home values will increase over the coming year.

At 11 percent confidence, reached an all-time low, according to the survey.
