Last year the tenant became behind in rent at around this time, when contact was made there was a promise that once they received their tax return then they would catch up on payments. They did, until now...

Rent is now currently 10 weeks in arrears. The landlord has severe medical issues at the moment and the tenant is avoiding the landlord. The property is also now being damaged, from the road you can see that the outside walls have massive holes in them and windows are cracked and broken. The garden/lawn is neglected but tha'ts neither here nor there in the scheme of things.

Is this sufficient to issue a notice of termination?

Note I am not the landlord but a friend, the landlord is quite ill and now her income is not being met and her property destroyed.

Any and all advice welcome.
