Then keep encouraging them to use the ACH transfer to pay rent. 

I like the ability to collect rent by ACH or credit card and access online or app is a must. 

B) New to the game - I've only been leasing homes for two years so far.C) Based on the idea this is a side business, not my main source of income.That said:I require my tenants to sign an ACH authorization for rent and tell them the rent is due on the first of the month, every month. 

I am really leaning towards 1 just because I feel that will cause the least amount of head ache, but my fear is without residents having “skin in the game” utility usage will be extremely wasteful.

It’s a pricey medicine for analysis paralysis, but quite effective it seems.But if you’d rather not go that route and do more of it on your own, here’s another suggestion...

I’ve done several rough calculations (obviously no one can predict the future of medicine, or anything for that matter) and my take home once I am an attending for all the specialties of interest to me will be about 150-200k after taxes, living expenses, and maxed out 401k and Roth IRA contributions.

They write their name on the bottom of the deposit slip.I also use ACH, Zelle, PayPal, Venmoe.

I was coughing, muscle aches, chills, and headache.If I was running my real estate business by myself I would have to had an unproductive day for my business as well.

I once delivered medicines to single family houses here in Missouri, whose residents where adults that couldn't live on their own and needed caretakers 24 hours a day. 

@Gary Nicholson, I make all my tenants pay through my property management software ACH transfers are free.
