I am working on an off market deal where the seller is wrapping up a ch 13 Bankruptcy that ends in September.

You build your deal finding/negotiating muscles and you meet a lot of people. 

Businesses use ACH for bill payment.

@Fili AguirreFor things like the initial deposit, I take money orders or ACH.

If rent not received by 3rd, a initial late fee $75 will be charged. additional $25/day thereafter for until rent and late charges are paid in full.I use cozy to get electronic ACH payments.

This incentivizes me to flex my creative muscles to produce quality and cheap work so I can maximize my return on the labor.I’ll probably do more of these types of deals in the future, personally.

. * I require all tenants to pay via auto-debit / ACH

Build credit, just like you are building muscle in the gym. 

There's zero benefit here, they just trying to muscle you and control the situation.Plus a long term lease doesn't even offer you anything in terms of security, they can break it with little consequence.

i use erentpayments.com for all;  application, credit check screen, and ACH rent collection.
