Theoretically a landlord can raise the rent to as high as he likes. If it's above fair market rent he will have trouble renting out for that high. If he raises the rent just to push you out of the unit he could be taken to court for discrimination.
The tenant is responsible for paying rent on time each month.
No more than someone who has lived there a month. No less either.
Generally none. If the tenant continues in possession once the lease term has expired he would be deemed a tenant at will, or a month-to-month tenant (if the rent is paid monthly) or a week-to-week tenant (if the rent is paid weekly). The frequency of rent payments determines whether the tenant is month to month or week to week, and also the notice the landlord must give before requiring the tenant to move. If its month to month the landlord must generally give one weeks notice to quit if he wants the tenants out. If you would feel more secure with a lease you might have to move. Many people never sign a lease after the first one expires and continue on a month to month basis.
Landlord has to relinquish the rights of the family to enter the unit for the purposes of gathering belongings. If the family continues to pay the rent then they can keep the unit (but not live in it) for another month or the remainder of the lease in some cases.
If the person has the legal right to live there on a month-to-month basis, he is a tenant. But we are presuming that you, the landlord, didn't rent the unit out to this person: perhaps your tenant did, known as subleasing. If you, the landlord, allowed this, then you have to have your tenant evict the sub-tenant. If you didn't allow this, then you have to enforce the terms of the lease, and make your tenant correct this problem immediately or you can evict him, which automatically forces the sub-tenant out.

Then the Tenant is considered a month to month renter. The Landlord or Tenant may change any terms of the deal with at least 6 months notice to either party.
If the landlord wants to sell the rental property, the tenant has different rights depending on what state the property is in. Usually, a landlord has to give 60 days notice for an intent to sell. Then, it is up to the landlord whether or not the property can be occupied by the tenant until the sale date. If there is a lease, the landlord usually cannot sell the property until the lease is up, but all states have different rules regarding occupancy.
if the tenant has a lease or on a month to month and his/her posessions are on the premises, yes, the tenant has to pay the rent, if something happened in the unit due to a domestic dispute with a room mate or landlord, then you may have to go to court to have it settled.
If there was a lease, the landlord has an obligation to try to rent it. Until then, the tenant owes the rent. If this was a month-to-month tenancy, the landlord should keep the first month's rent, and return the security deposit and last-month's rent, if any.
Depends on the state
No.
