One segment of the market that may benefit from the Tax Reform may be multi-family. According to Real estate weekly, some people may decide to rent instead of buying and rents may rise as a result. Also, foreign investors may move into more multi-family properties due to the decrease of the Corporate tax rate to 21%.
Rents have been declining for the last 2 years in the Manhattan market but if more people who can buy decide not to buy this can affect the rental market.
Also, if interest rates rise, this may be a secondary consequence of the new tax law, and they may affect the starter apartment market in Manhattan and increase the amount of renters.
