When renting a house in New York, can I cancel the lease at any time after signing the lease?
You may not. Generally speaking, the lease will take effect immediately after it is signed, and neither party can terminate the lease in advance. According to the relevant laws of the United States, if the tenant has signed a long-term lease, he/she shall bear the rent for the entire lease term. Even if he/she is forced to move out, the landlord still has the right to require the tenant to pay all the rent.
