From internet search/Turbo Tenant:  'In certain instances, breaking a lease in California due to a medical condition might be possible.

This is something their screening probably would have caught, or their system would have a legal procedure to deal with it.

@Kasey Hardt very interesting,  didn't realize this was a pattern but even I've got friends that are getting recruited to the area for medical device startups etc, so could be a very interesting trend to watch.

Learn the eviction procedure for your area, perhaps contact a lawyer in the field to help you with this one, and get the fraudster you're currently housing out on the sidewalk to sleep in a cardboard box where they belong.You're going to lose plenty of money here, but this will never happen to you again, and you can minimize your losses if you move as quickly as possible.

Quote from @Brandon Larson: It's important to have established policies and procedures, but I wouldn't put a lot of effort into that with only a duplex under management.

You should never use a debit card or pay for medical expenses from your HSA, ever!

The standard legal procedure, as far as I understand in NC is the landlord must make reasonable effort to re-rent the property (which I will), and any vacant time till new tenants are found must be paid by previous tenants.

Quote from @Jared Haxton: Hi BP Community,I own a 2-bed/2-bath condo in Prescott, AZ (near Embry-Riddle Aeronautical University, hospitals, and medical facilities), and I’m exploring selling it via seller financing.

As someone who did something very similar to this for the last 2 years - rented out my 2nd private bedroom and bathroom in my apartment (rental) furnished to traveling professionals and medical students - I think it's a great idea! 

The hospital is going to ask for it over and over again during medical checkups.
