Housing Regression is one of the playgroung level competition on Kaggle.Good place to get your hands dirty and a great way to begin one's Machine Learning journey.
This is the competition where I first tried out stacking and ensembling .Kaggle has some amazing kernels immensely good at explaining the topics.
Some Kernels which are great to get started with are.
1.Comprehensive data exploration with Python by Pedro Marcelino
2.Stacked Regressions to predict House Prices by Sergine

Do make utmost use of kaggle its a fun and brilliant place to learn Data Science.
