Project:

This study examines the impact of the state and local tax (SALT) deduction on home price capitalization. By exploiting the recent cap of the SALT deduction put in place by the Tax Cut and Jobs Act of 2017 (TCJA17), we compare the effect on home prices in areas with high salt deduction to low salt deduction areas. The data comes from two sources, Zillow Transaction and Assessment Database (ZTRAX) and the Home Mortgage Disclosure Act (HMDA). Using several keys, this data is joined to create a national sample of home characteristics linked to mortgage and individual characteristics. Using this data, we can estimate an instrument of potential SALT deduction amount and estimate the impact the policy change had on sales price. Currently the data is saved in many parquet files to reduce the size, however the raw data is several TBs.
