Does she have documentation from a licensed physician claiming this animal to be of such.   

Potential tenant with felony prescription medication conviction, not violent, wasn't incarcerated, sounds like previous landlord said he pays on time.

Medical space is tricky with 85% of physician offices now owned by hospitals.  

If it had anything involving heroin or prescription opiates I would also say HELL NO.  

I simply told my tenant that if she can provide a legal prescription from a licensed physician, she can have the dog but must provide proof of all vaccinations as they become due from a licensed veterinarian.

Sure if you are a physician or a general contractor there are reasons to have a complicated asset scheme to reduce exposure to a significant judgment in a personal injury case.   

I haven't seen physician loans in a while.

Link to an Philadelphia Bar Association opinion on whether a physician/attorney can receive referral fees for referring a patient to a personal injury firm.

The first year of residency is tough (can say from personal experience - wife is a physician).

@Richard Tavetian if you want clear title the property taxes have to be paid prior to close. 2) More than likely there exists a prescriptive easement or a recorded easement on the property. 3) Follow you states landlord tenant law and give notice of rent increase or termination of rent.
