No, not if the lease says you are renting the entire property.
If the lease says you are renting only the house, for example, not the land where she want to build a shed, then she may be within her rights. If it says something brought like "the property 123 Main St.", then that includes all the land so it is yours to use, not hers.
I suggest you look at it from her point of view - she needs a place for her stuff. Tell her that you have leased the entire property but if she needs some of it "back", then you can modify the lease (in writing) for a reduction in rent.
What a landlord verifies is completely up to the landlord
Normally under those circumstances you should be covered under the landlords insurance because you are renting from them and you and the house are there responsibility.
A property owner who is renting the property out to people to live in.
Anyone who requests a credit report must get your prior permission. This includes a landlord. You must provide he information the landlord needs before they can legally get a credit report, but this is a requirement for a lot of landlords before they will rent you their property.
Landlords have different policies. Some may ask you to repay until re-rented, pay the remainder of the lease, or pay a lease break fee. You always must provide the landlord with proper notice.
I dont believe they can. Even though it is the landlords property, when it is rented out to a tenant then it does not mean they are able to come in and out as pleased. You have right when you are a tenant. I know that they need to have a notice requirement to enter.
In the situation you describe, is the landlord the sole owner, and you are a renter or lessee? If the landlord is the sole owner of the property, and you are the lessee, they remain the landlord/sole owner despite where they may live. If you are renting the property from the landlord, you are only a lessee and not a joint owner.
If you are the one renting the property you can not deduct this from your taxes. If you are the landlord you can receive a deduction on your taxes for owning the property.
No. This is an act of god. You should notify your car insurance.
Tenant and lessee are the same thing, they are a person who rents property from a lessor who own property that he wants to lease.
That depends on what state (or country) the property is in.
You should make very clear what are you expecting and what are the landlords expecting from you.
