For their upcoming renewal, I would like to draw up a brand-new lease and add an updated pet policy so they will know my rules if I give written permission (they have asked us to consider a dog- which current lease says no pets, but considered case-by-case). 

It's pretty easy set-up and then the guest can scan a QR code that is in the home, with a shopping list/links of all the items. 

What things from the buyers side are they considering when making an offer? 

That's the reason I'd consider holding on to them. 

I have set myself up with an agent automotive and I use the properties' prices to get familiar with the BP calculators.

Considering purchase in Georgia market that is currently rented as Section 8. 

Would you consider this a deal?

And, persons with "cash" income are not even considered by me.

Should I consider lowering the rent price further, renting to these concerning candidates, or pivoting to a short-term or mid-term rental strategy (considering I live out of state)?

STRs are not the only option we are considering, and she may be able to reduce most of her expenses.
