PM suggested month to month...

[Tom Chen]

My first duplex in Syracuse, NY is finally getting ready to be rented out.  

My PM said they have a couple with 2 kids...

The issue is, the wife has good credit (upwards of 700), but the husband has sub-600 score. The previous landlord did not want to see them leave, but spoke highly of them. The PM has actually seen their last place and it was very clean. 

PM still feels a bit odd that the husband has such bad credit so suggested month to month lease. 

Does this make sense?  It kind of did with me...am I being gullible?
