Which applicant should I rent to (bankruptcy vs illegals)?

[Ling S.]

I am renting my newly purchased sfh and really need your advise on picking the tenant. Both is ready to move in this Saturday oct 1.
Applicant #1: the couple with 2 kids and a dog. Combined income is 2x monthly rent. Great references. Seems really nice people. However, one of them is illegal immigrant. They are going to commute over 1 hour to work after moving in. So i am afraid that they may only stay for 1 year and move back.
Applicant #2: high income. Both working, 3 years, 10 years at the job. Couple with 2 older kids. One filled chapter 13 bankruptcy 2 years ago because of 2 years unemployment. The Other filled bankruptcy 1 year ago helping out the spouse. They rent the same apartment for last 7 years. Likely will be long term tenant.

Or maybe wait for one more month to find better tenant.

Please help me make a decision.
