What is the proper way to modify a lease

[Mark Husband-Wood]

I understand that it is best to write the lease as intended in the first place.  But, let's assume that's not possible.

If something in a lease needs to be changed/modified, what is the best way to do so?  

Cross out the portion you want to change, and hand write the desired words?  Then sign/initial and date the change?

Does the tenant also have to sign/initial and date the change to signify agreement?

Thanks!
