A landlord may legally evict any time you are late with the rent.
Even if you are just one day late one time.
In answer to the question 'Can your landlord evict you', the answer is 'yes'.
To evict, he needs a reason.
I am presuming we have three components here: a landlord, a tenant, and a subtenant. The landlord in this case is presumably renting to a tenant, while the tenant is presumably renting to a subtenant. I presume that tenant has a lease while the subtenant doesn't. The tenant becomes the landlord for the subtenant. Since there is no lease (in most states subletting does not involve a lease) in this case, the tenant who is the subtenant landlord can evict the subtenant. While the main landlord can evict the tenant -which automatically evicts the subtenant -only the tenant can evict the subtenant. But the main landlord can evict all by evicting the tenant.
Your landlord can evict you and sue for back rent.
The question is unclear. If the tenant was successfully evicted, there would be no second opportunity. Perhaps you mean the landlord started eviction, abandoned it and then started again in six months. That is fine, he can do that. There could be exceptions, of course. Imagine the landlord tried to evict because the person voted for the wrong guy. The court said you can't do that. Then the landlord can't evict for some other made-up reason because the first try didn't work. It must also be remembered that state and local laws may differ. And, different laws apply in other countries.
Yes.
no they can't
Either he or his lawyer.
no
No. You have the right to ask questions about this matter as every tenant who faces the uncertainty of his landlord being under foreclosure. But remember: as long as the landlord has control of the property he can still collect rent from you and evict you if you don't pay it.
The landlord can correct the problems for which the house can be potentially condemned. But the landlord cannot evict the tenant just for saying that.
Of course. You are still living there and your landlord's finances do not impact yours. He is still entitled to rent or can simply evict you.
