NEW YORK (TheStreet) -- Stock futures were slightly lower on Tuesday as U.S. house prices rose and durable goods orders declined. 

S&P 500 futures were down 0.35%, Dow Jones Industrial Average futures fell 0.25%, and Nasdaq futures dropped 0.38%. 

U.S. house prices rose 0.9% in March, according to the Case-Shiller Home Price Index, pulling the year-on-year increase up to 5%. Nineteen of 20 cities measured showed gains, led by a 3% increase in San Francisco. The increase was as economists had expected. 

Durable goods orders dropped 0.5% in April after jumping 4.4% in March. The reading was in line with economists' forecasts. Excluding transportation, durable goods rose 0.5% after a 0.4% increase in March, better than an expected 0.3% increase. 

"April's durable goods figures confirm that, following the earlier disruption caused by the unseasonably cold weather in the Northeast and the West Coast port dispute, the factory sector was getting back on track as spring approached," said Paul Ashworth, chief economist at Capital Economics.
