These days, we use the Southwest Visa -- we get points (which can be used towards free travel) and with $110,000 in spend per year, we get a companion pass so my wife (or whomever) can fly free with me.

@Jeff Greenberg just because someone accepts a service or companion animal it doesn't sound right that you can't give a no cause notice.

I do not leave the house without them & my constant companion laptop.

Make sure you get the companion books also THE BOOK ON FLIPPING HOUSES & THE BOOK ON ESTIMATING REHAB COSTS (copied from @Brandon Turner best books to read pdf)

Your blow-hard companion may not fit the bill but I've noticed that more mature investors are just naturally more skeptical of future growth outside the metro.  

I understand the comfort of a companion animal, but if you're making the claim, you should have to have something to back it up!! 

Common terms for these animals: Emotional Support Animal (ESA), Comfort Animal, Companion Animal, Therapy Animal.

Don't get "service animals" confused with "companion animals".

@Dustin DuFault et alAres Companion is a nice alternative to a working flashlight:)Another suggestion: SWD .38 cane gun or Tromix Super Shorty (fits nicely under a trench coat).

so, considering that even if the tenant is neither blind nor deaf nor mobility impaired, there may now be a plethora of other instances in which suddenly turning away 'pets' can easily develop into a lawsuit for 'discrimination' and suddenly the pet is a 'therapy aide' or whatever, so what sort of documentation would be adequate enough to distinguish a bona-fide service/alert/therapy dog, from a dog that grandma simply wants have around as a.. companion that comforts her and makes her feel better just having around (which is what a pet is, aint it?)
