Why was my lease not renewed?
Your landlord choosing not to renew your lease can have several different outcomes, and the sooner you know what will happen after the end of the lease the better you can prepare yourself. You may become a monthly renter when the lease ends, you could be presented with a new lease agreement with different terms to your last one, or you may be need to vacate the property. As a tenant, it is best to give yourself at least a month prior to the end of your current lease to understand how you will be proceeding when your lease ends. It is both your responsibility and in your best interest to check with your landlord how they would like to proceed when the current lease expires.
Landlords do not generally need to give a reason for not renewing a lease with a tenant. A lease is a contract between the landlord and tenant for a specified amount of time, and neither party obligated to renew this contract when that timeframe expires.
