The big thing is they need to be able to have a checking account for the ACH transfer. 

Gets put directly into my business checking account.I also take Zelle, PayPal, Venmo, ACH.

The housing authority will pay the landlord their portion directly (mailed check, or you can sign up for ach deposit).  

This has been a real struggle - I have required ACH payments  for the last 2-3 years and up until now this has not been a problem but has required that the borrower/renter changes bank to one that knows how to do it (still amazes me how badly trained some bank personnel).

Have the tenant contact the debit card issuer and ask if the card allows "ACH debits" as if so the card issuer can provide the routing number and account number to use and the tenant can enter it like a bank account in a payment service.  

My tenant can fill out maintenance requests and pay monthly rent via ACH payments they can also use a credit card.

RentRedi offers a pretty good applicant process, has a phone app, and has online ACH for rent payments that is only $1 for the tenant.

ACH is freeTakes about 5-7 days for the funds to hit your bank accountExcelI use an excel spreadsheet to track my check register.

Also Cozy is free for the tenant if they use ACH, a lot of other services charge them. 

It’s in a class c neighborhood Appreciate all the additional input as well I guess it makes sense you can set up ACH payments and this way the payments are automated and you can make sure they pay on time.
