My adult handicapped daughter decided to move to TN since I was. 

Its hard for me to physically meet up now as Ive become handicapped..but I have 30+ years experience as a realtor and Id love to chat sometime :)

We PHYSICALLY helped him move all of his stuff out (he's handicapped).

Because of our location and amenities plus the fact that these are ground level garden-style homes across from a rapid transit station we are exploring the idea of converting to full ADA spec handicapped accessible.

We're replaced a few toilets with the chair height ones and, in one case with a senior couple with health issues, I've added a handicap seat available from Lowes.  

My car was broken into and a witness saw my neighbors daughter and a teenage boy still my mother's handicap placard.

I would disclose to my buyers the issue and let them handicap the risk reward.

However, you will not be able to afford the rates.So, there is the undue burden on you as the landlord. that allows you to say you can not make accommodations for such an animal.It is the same as if a person applied for an apartment on the second floor and after being accepted stated they were in a wheel chair and since the apartment is on the second floor you as the landlord must install a ramp or lift that makes the second floor handicapped accessible.

The last really good German Sheppard destroyed all the carpets and a door, went after and growled at everyone, and jumped into the lap of my handicapped tenant!

To which extent, you need to thoroughly understand, and know the facts, concerning the potential out comes and handicap or give a probability to each, based on your own logic and beliefs.
