She will not qualify as a tenant due to the terms and conditions of my screening and application criteria, primarily because she is unemployed. 

Is your screening process as vigorous as a single unit2.)

At one, when I opened the screen door, I could already smell the stench of garbage!

If an HOA wanted to implement policies with regards to screening tenants, how long is their leash?

They cannot "screen" the offers.

Not cracked.

Have you removed the shower head and checked for leaks, a cracked shower elbow and made sure that the threads in the neck where it threads into pipe connection in the wall was property wrapped with Teflon taped and tightened?

Without photos of he cracks, both ceiling and driveway, I couldn't give you an opinion.

Often employed by professional tenants to mislead mom and pop landlords.For me it is a obvious red flag when screening.

She will owe rent until a new tennat moves in and will be responsible for all your costs associated with finding a new tennat....advertising, screening etc.There is absolutely no reason for you to do her any favours.
