This paper measures the welfare effects of removing the mortgage interest deduction under a variety of implementation scenarios. To this end, we build a life-cycle model with heterogeneous households calibrated to the U.S. economy, which features long-term mortgages and costly refinancing. In line with previous research, we find that most households would prefer to be born into an economy without the deductibility. However, when we incorporate transitional dynamics, less than forty percent of households are in favor of a reform and the average welfare effect is negative. This result holds under a number of removal designs.
