@Daniel Dietz, The hold period qualification is the 5 years prior to sale. 

I am looking to purchase section 8 occupied properties in Atlanta, GA. I have a property management company that handles everything. What steps do I have to take in order to qualify as a section 8 landlord, if any? Or...

And if yes to the latter, does that mean they meet your qualification standards in general?

I understand FHA qualification and buyer acceptance are unlikely.

If it's a larger organization, feel free to inquire about their different staff qualifications.2.

The phrase "then current underwriting requirements" refers to qualification, not loan terms. 

I have a DTI in mid 20% and a FICO above 835 and have seasoned the rental income over 18 months, so qualification shouldn't be a problem.

It is the tenant's choice how to apply though and if they meet the qualifications with some adults as occupants, it isn't appropriate to deny them.

And I tell them make sure the rent money is in the bank on the first.Another tenant, slightly better qualifications, missed one electronic payment recently, but tells me he had to help a relative out, and spend $29K.
