S.A.
In any case, if the landlord doesn't start to pay the payments then his property will be foreclosed. Whether someone else comes in and buys the property is yet to be seen. Then what if the new property owner wants to raise the rent? (I think they can do that)
I would do some research on the internet to see about renters rights.
And I agree with you...if you do have to move you are not going to want to move right when you are due or even right there after. Better to do it before if it is more than likely what will eventually need to be done.
