The HAP portion of the rent comes in by ACH on or before the 3rd of the month.The tenants themselves need to be screened properly like anyone else.  

Personally, I use Rentec Direct for my ACH payments and rent collection. 

Give them an option to pay online or by ACH, for instance.  

Do I understand correctly that I erentpayments.com allows ach debit allowing the landlord total control (tenant can not cancel the auto deduct from their account without landlord approval)?

But, since you're on a month to month contract, if you want to leave, you just have to give 30 days notice.Then, they (the complainers) will usually find a few maintenance things they want fixed, just to flex their muscles a bit, which we would take care of, and then everybody calms down again.I also never had anyone move over an increase.  

Bank to Bank ACH transfer.

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

You don't need to flex your muscle or fear that in being flexible the tenants will walk all over you.

You could encourage her to switch over to automated ACH payments with a discount perhaps.  

I'm in the approval process to accept ACH payments.
