You should feel free to use any and all features that are present in this dataset.</p>\n<h2>Goal</h2>\n<p>It is your job to predict the sales price for each house. For each Id in the test set, you must predict the value of the SalePrice variable.</p>\n<h2>Evaluation</h2>\nKaggle leaderboard standings will be determined by <a href=\"https://en.wikipedia.org/wiki/Root-mean-square_deviation\">root mean squared error</a> (RMSE).\n<h2>Submission File Format</h2>\nThe file should contain a header and have the following format:\n<pre>Id,SalePrice<br></pre>\n\n",
