That is up to the landlord.
No. A condition of the lease being made is that there will be a co-signer. If no one will co-sign, then you are out of luck.
Are you seeking someone to co-sign a loan or lease with you?
Yes, typically both the husband and wife must sign the lease agreement if they are both listed as tenants on the lease.
No.
To get a cosigner for a loan or lease agreement, you need to find someone with good credit and income who is willing to sign the agreement with you. The cosigner is responsible for the debt if you are unable to pay. The lender or leasing company will typically require the cosigner to fill out an application and provide financial information.
You just ask them to pay monthly and have them sign a lease saying they will.
In order for the lease to be binding on a lessee, every lessee must sign. If the terms of the leases are the same, you can ask all three tenants to sign the same lease. If the terms and durations are different, a separate lease is recommended for each tenant. It is also recommended that you review your governing documents to determine whether or not it is legal for you to rent to three separate tenants.
Hell yeah the only thing non refundable is application fee & administration fee.
Until you are 18, or are legally emancipated, you won't be able to sign a binding contract for the lease. But the owner may accept the cosigner's signature.
Your landlord can offer a lease renewal at any point in the lease term, however, he cannot force you to sign or raise your rent until the end of the contract.
The first step would be not to take out (or renew) the lease on any dwelling that you do not plan on living in. Legally if your name is on the lease you are responsible for the monthly rent. If the two of you have children together - who live with her, you need to come to a decision about what to do, so the children don't end up on the street. But you have no legal responsibility to sign a lease for her.
You do not allow them to move into the premises or you give up the idea of having the protection of a lease. Once you let them move in without signing a lease they are your problem. It should be noted that a tenant who refuses to sign a lease is giving you a loud message about what type of experience you can expect in the future.
