Renew or Extend a Lease

[Debra Humphries]

My tenants 2 year lease expires in about a month.  They would like to renew the lease for another 2 years.  (they have been great tenants.  Have paid their rent on time every month).  Should I have them sign a new 2 year lease or should I extend the current lease for another 2 years.  The only thing that is changing from the current lease are the dates of the 2 year term and the number of tenants.  All other terms of the lease are the same.  The rental property is located in Bowie, MD.  Thanks for your help.
