In my experience, section 8 tenants can be a real pain and should be vetted more from a holistic perspective than from a traditional quantitative perspective.

If we determine that your dwelling should not be occupied because of damage or risk to property, health, or safety, we may, at our option, terminate this lease.

What are the biggest pain points you've encountered when trying to find distressed or off-market properties?

Some states require an established relationship with the health professional, not just one evaluation, but many others, it’s just a letter from a professional if disability and/or reason for animal is not readily apparent.

But sheesh that's just so sad and it does nothing but cause more pain and suffering for everyone else who isn't even involved and has to pay for the wrong doing of others, ie increased insurance etc.

Switching software can be painful.

I priced it only about 14% higher than the long term rental which matches traveling health professionals' budget on Furnished Finder.So I'm leaning toward longer term rental because even if I secure midterm tenant, that 14% more isn't really worth the potential vacancy.

You can always request Medical Documentation: Request documentation of her medical situation and a letter from her doctor to make sure her condition will improve and ask if she is up for taking care of the property while she is recovering.Check Her References: Contact previous landlords for references to get a sense of her reliability as a tenant.Lease Terms: You can always start with a 6 month or a 1-year lease option if you have a good idea of her overall health condition.
