Should I accept this tenant

[Xin Z.]

Hi all,

I have a potential tenant who had credit issues years ago.  I normally charge two months deposit for tenants with bad credits, but they told me they can't fork up so much money at this time.  Should I accept them with just one month's deposit?  Is there any other thing I can do to help prevent future problems?  The house is in an A-/B area.

Thanks a lot!
