Fannie Mae’s Home Purchase Sentiment Index zoomed to an all-time high in May as consumers get more upbeat about their paychecks and home selling. In May, the index reached a reading of 85.3, which follows an 18-month low reached in March.

Three of six components the index measures registered increases last month, led by a 7 percentage point increase in the number of consumers reporting significantly higher income than a year ago. Also, the number of consumers who expect home prices to increase over the next 12 months rose 5 percentage points. Consumers were also upbeat that mortgage rates would decrease over the next year as well.

That said, the index indicator on whether it’s a “good time to buy” dropped 1 percentage point to an all-time survey low in May.

“Continued home price appreciation has been squeezing housing affordability, driving a two-year downward trend in the share of consumers who think it’s a good time to buy a home,” says Doug Duncan, senior vice president and chief economist at Fannie Mae. “The current low mortgage rate environment has helped ease this pressure, and fewer than half of consumers expect rates to go up in the next year. While the May increase in income growth perceptions could provide further support to prospective home buyers as the spring/summer homebuying season gains momentum, the effect may be muted by May’s discouraging jobs report.”

Here’s a closer look at additional findings from Fannie Mae’s latest index reading:

• 29 percent of Americans say now is a good time to buy a home, a drop of 1 percentage point from March and an all-time survey low for the second consecutive month.
• 52 percent of consumers believe now is a good time to sell a home – an all-time survey high.
• 42 percent of Americans believe that home prices will go up.
• 72 percent of Americans say they are not concerned with losing their job, a drop of 2 percentage points from March.
• 18 percent of Americans say their household income is significantly higher than it was a year ago, up 7 percentage points from March and at an all-time survey high.
