Will the New Tax Law impact Home Sales, Inventory, and Price Growth in Certain States? dated 12/28/2017 by Bill McBride of CalculatedRISK Finance & Economics
"Housing and Taxes: A key change in the new tax law is limiting the deductibility of State and Local Taxes (SALT) and property taxes to $10,000. Many analysts think this will hit certain segments of the housing market in states like New York, New Jersey and California."
"My sense is the low end of the housing market will be fine. The Mortgage Interest Deduction (MID) will be capped at interest on a mortgage up to $750,000 instead of $1,000,000, so the lower priced markets will not be hit by the reduction in the MID. There might be some additional taxes for these buyers due to the limits on SALT and property taxes, but this should be minor.
I also expect the high end of the market to be fine. The high end is already doing well even with the MID capped at $1 million. For these buyers, the bigger impact will be the SALT and property tax limitations, but there will be offsets for these buyers due to the lower rates - and these buyers will likely benefit from the corporate tax cuts. Many of these buyers will also benefit from the changes to the Alternative Minimum Tax (AMT).
It is the upper-mid-range in the certain markets that will probably slow. This might be in the $750,000 to $1.5 million price range. These potential buyers probably don't benefit from the AMT or corporate changes, but they will likely be hit by the SALT and property tax limits.
There could be a ripple effect. If the upper-mid-range slows, that could impact some of the purchases in the next higher range."
