Financial Future Of Your Loved One
You have to be absolutely sure you can handle the rent before you risk the financial future of your loved one.
Another option might be paying six months or more of the rent upfront. The only downside to this is that it can be difficult to come up with so much money upfront, especially when your credit is so bad. If you have the spare cash to do this, you could avoid a co-signer and show the landlord that you are serious about moving into the apartment.
If you can stand sharing your home with someone else, then getting a roommate could be a good option. The roommate can sign the lease and you pay the roommate each month. The person you choose to live with will have to have good credit of course or the plan is not going to work.
