Upfront communication and honesty is the best cure. 

If they owe you any money, you can probably file faster for that than you can a non-financial cure. 

Send a notice to cure to both the tenant and co=signer.

As her portion to pay includes a basic allowance for utilities and if they are high, they will do a one-time or ongoing change in what they pay.That said, just send her a notice to cure or quit and copy it to the housing authority (which your lease with them requires).

If the husband does end up moving in, you'll have to issue the tenant a notice (in my state it's called a "cure or quit" notice, but I believe in your state it is called a "comply or vacate" notice). 

I was stuck in Paralysis Analysis and this program cured me of the condition.

I always love checking out what other people did.I'm doing some reading and it looks fairly easy to do, though reviewers mention a 3-day cure time and to also make sure you coat with like 3 coats of poly to seal the paint and keep it from chipping.

My point is it is not our responsibility to cure the ills of society .

It would be a poor idea for someone without training to think a gun will cure their problems.

@Michael Montana data is the cure for fear.
