@Derek Buehner many banks/CUs have overlays requiring 2 years tax return history for STRs, but if you work with a direct lender like Academy Mortgage, we can use just 1 year on tax returns for income qualification.

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

This does two things, 1. screens out tenants that don't meet your qualification criteria and 2. allows you to see how truly interested a prospect really is. 

What type of qualifications would be there to be in such a group.

One of the advantages is that you're not required to provide tax returns or a debt-to-income ratio; instead, the lender will assess the property's income for qualification.

As far as qualification they still look at debt to income, credit score/worthiness, and again depends on the county you are purchasing in and the AMI. 

They're making sure that it fits into their "box" and you meet all qualifications for the loan for them to agree to lend you the funds. 2.

@AJ Watkins They have extended these tax credits so you should still be eligible and have changed the qualifications. 

Consult a qualifed professional.  

Similarly, you can only use 75% of the income derived from rent to meet the debt-to-income qualification.
