@Joseph Firmin I can only to talk for NYC which is where the new laws have been primarily aimed at. Everyone is readjusting their calculations and strategies, some are still a bit shocked how the new laws went right through so smoothly. Those who don't feel comfortable owning with the new laws and what else the new political movement has in mind for 2020 and beyond are in fact exiting to other more landlord and business friendly states. It really depends on your investment profile.
The investors who recently bought property at prices which couldn't possibly cashflow at the current rents, who bought with intention to significantly raise the rents have been burned badly. Also those who secured large mortgages based on future projections, with the assumption that rents will be significantly raised over the next few years are underwater now.
Current property owners who don't plan on exiting the market and any new entrants all have one thing in common - deep pockets, to survive non paying tenants who destroy the property and can take a year or longer to be evicted and tight caps on rent increases among other new restrictions.
