What are some of the head aches/risks involved in that process?

And yes, when I set up a link to my personal account in order to ACH funds back and forth, I provided them with my sign-in and password. 

Certified funds (cash, money order, or cashiers check) or an online ACH payment.

If you just look at them like they're a math problem, a lot of heart ache over whether to pull the trigger  or not goes away.If the market value is 110,000 and you're buying it for 40,000 below market value, that's 70,000. 

I accept ACH from the tenant's bank to my account, checks, money orders, and cash. 

People do everything online and we found that the first thing a tenant does is setup automatic ACH-a Landlords dream come true.   

One thing I'm doing this month to move closer to best is setting up ACH/auto-draft rents. 

ACH Fees if any typically paid by tenant12.

In your situation as a new business an accountant will be able to plan properly for the future as well and may save you money and head ache down the road.

All of my tenants pay via Quickbooks invoices that I e mail to them monthly (ACH transfers), but I have had some that want to send checks occasionally (usually a parent wanting to pay for rent as a lump sum).Cash is ok, just give them a receipt.
