NEW YORK (CNNMoney) -- U.S. stocks were set to edge higher Tuesday, following a report that showed home prices rose for the first time in eight months in April.
Dow Jones industrial average (), S&P 500 ( ) and Nasdaq ( ) futures were more than 0.3% higher ahead of the opening bell. Futures measure current index values against perceived future performance.

Lawmakers began debating an austerity package Monday that is needed to secure financial aid for the struggling country. Discussions continued Tuesday, and Greece's parliament will vote Wednesday on a five-year budget plan.

"Uncertainty persists ahead of the Greek budget vote," BNP Paribas said in a research note. The austerity measures are largely expected to pass on Wednesday, but markets will likely remain "highly skittish" until then.
Longer term, while jitters about Greece's debt crisis and the health of the eurozone will still hang over the market, they could be overshadowed temporarily by optimism about the upcoming earnings season.
