Timing of End of Lease

[Amy H.]

My apologies in advance for what is likely an old subject; however, I can't seem to find this addressed in the forums anywhere:  

What are the best months in which to end a lease?  Also, we just purchased a property, so this will be the first lease:  If the best month in which to end the lease is several months off, what is the best way to approach it:  Make the first lease longer than one year or shorter?  Any ideas or old forums posts about this that anyone can point me to would be greatly appreciated!
