If we assume that my recollection is accurate, then perhaps you have remedies.

We ended up having a mold issue and we found a great mold remediation guy who did it at a fraction of the cost of everyone else who came out to look at it.  

Petitioner testified that the lessee, Economopoulos, pointed out to her a dead rat, a bee's nest, and several leaks during her single visit, yet petitioner presented no evidence that she attempted to remedy these problems during her period of ownership.

Remedies.

If home remedies reduce them to just a few, they can be very hard to find.

I just purchased the property and the previous landlord had remedied the situation by replacing the bad drywall and using mold resistant paint.  

Soooooooo, am I wrong that financial planners say the real remedy is to keep working to 70 or older or move to a cheaper state to live.  

The landlord will probably treat any lingering strong smell equivalent to smoking in the unit and take appropriate remediation until it's clean.

Most likely the remedie will involve the property itself or paying for the repairs that were not disclosed.

The leases we use have the following wording in regards to early or late termination of the lease:"If Tenant remains in possession of the Premises after the expiration or sooner termination of the Term without Landlord’s written consent, such holding over shall constitute a default hereof and, without limiting any other right or remedy of Landlord at law or in equity, create and be deemed to be a tenancy at sufferance, terminable without Notice of any kind except as may be required in accordance with law, but subject to all other terms of this Lease insofar as the same may apply to such a tenancy, except that Tenant shall pay, in addition to all other charges payable by Tenant hereunder, for each day that Tenant holds over, Rent at an amount equal to two (2) times in Missouri and one and one-half (1-1/2) in Kansas the rate (on a per diem basis) of Rent herein provided to be paid during the last month of the Term.
