@John Gerwatosky, how big of a pain is this worth to you? 

So although this can be a pain, I do recommend getting them to protect yourself. 

Or it can be a pain to even go see the property, sometimes landlords don't make themselves available for showings or they are willing to wait for a tenant that meets their high criteria.

Active, smaller investors it presents a lot of challenges and I believe few will do well (or experience a lot of pain getting there). 

The reason for this, as @Rick Baggenstoss pointed out, is that accepting Section 8 vouchers requires that a landlord submit to a painful bureaucratic approval and inspection process that all but guarantees a month or more of vacancy at the start of each lease.

Lugging laundry to the laundromat is a major pain.

Anyone have experience in this process, or any tidbits to help us avoid any unnecessary pain?

It is an unfortunate pain.
