The specific answer needs to be provided by an "elder care" attorney in your local area.

I would also explore a resident manager to take care of the property if you can't find a qualified company.These smaller properties are difficult to manage due to their size and the inability to retain full time payroll.

Don't care what they think about you - your goal is to get a deal.Be ready to walk away (or hang up) at any moment.

It simply states in their lease that they are responsible for snow/lawn care. 

I don't care if a business is drugs or not...there is a skill to running a successful business.

I've been in contact with my tenant's parents and they are taking care of everything. 

My husband was taking care of that part of the business.  

HOWEVER, I’d be careful to represent the seller, check your local laws or talk to people doing this in YOUR market.And here comes @John Thedford

Well if you go to my website you can see I am a super sexy dude with a brain 3 times the size of your dogs, kind and awesome eager to make a deal with you.

OC is large, so in "gentryfied" OC, you're right around SFR range at $340k, but in other parts, (& safe) you'll be fine.I would suggest, if you care, to consider a fixer.
