@Jim K.If high on cold medicine counts I've been guilty once or twice.

I only do ACH transfers. 

Bank to Bank ACH transfer.

That way the head ache of evicting is in the sellers hands.

If the neighbor has any potential violations of his own, give him a taste of his own medicine.  

The country she was in had socialized medicine.

@Michael HassellI send out invoices from my quickbooks account and my tenants pay by ACH transfers.I get alerts by email every time the payments hit my checking account.Seamless.One tenant is old school and paranoid and insists on mailing checks per lease.That's fine.She mails her checks to my POBOX.

I'd suggest agreeing to waive the fee if they elect to pay automatically though ACH transactions.

Less heart ache and usually more repairable.

We typically only deal with ACH but I would assume there would be similar rules for regular checks also regarding the time frame to return them.
