    Hi @tamararidwan,

    The accuracy is a performance metric dedicated to classification tasks. 
    Prediction of house price, like your project, is a regression task (target variable is continuous). So RapidMiner propose RMSE as performance metric.
    However if you want a percentage as performance metrics for your regression task, you have to use (inside your Cross Validation operator) the Performance (Regression) operator  and check relative error.

    Hope this helps,

    Regards,

    Hello @tamararidwan

    @lionelderkrikor already gave some great inputs, one thing to add is squared correlation  (R squared, Range between 0 to 1 in rapidminer). The model is better if its closer to 1, most of the time above 0.6 is acceptable and it also depends on the problem domain.
