With respect to the lease issue, it is going to depend upon whether your landlord is agreeable to remove your wife from the lease. The landlord does not necessarily have to agree to remove her, especially if she still comes by the house.
Your lease may not allow for her to be removed. Consult with a local attorney to see if this is possible. The landlord might think this does not benefit him therefore he won't do it. Good luck.
