It is now day 2, the landlord and his guy are at the house with my wife, who doesn't have faith in their ability to do the work properly (motherly intuition?).

My only delimma is a slight language barrier, the tenants primarily speaking Spanish, and me intuition telling me they are not being upfront with how many people are living in this property.

As soon as I get the bills, I set them up to be paid by the proper day.For rent payments, I used to use Intuit Payment Network and loved it ($.50/transaction!)

@Joe Henry, Some of my tenants are uncomfortable with ACH or run into technical difficulties with IPN (Intuit Payment Network) which is what I use. 

I don't know if this is "right or wrong" but it seems intuitive to me.

. ;) I manage 50 units and have placed 'good' folks in similar situations and have paid the price...It is highly likely (I believe) that your intuition will turn out to be correct.Of course, it makes sense to weigh risk vs reward based on rent rates/candidate pool/current occupancy/etc...But, if I were a gambling man (I'm not), I'd lay cash that the new tenants are late by month 3 and unable to pay by month 6...

The main disadvantage is that Intuit will only support the program for three years.

It's also an Intuit program, but free.
