According to the Tenant's Rights Act of 2009, if you have a lease, the new owners are required to honor that Lease.
If you are a Renter, you must be given a reasonable time to move, I believe it is 90 days, but you can Google it and see the details.
You certainly may negotiate with the new owners, they may be happy to have you. Talk to the Agent who knocks on your door.
At the worst, you will be offered some moving money and 30 days.
Good luck and may God bless
