I have a tenant whose therapist is recommending she buy a therapy dog to help her and that even though our lease agreement says no pets, that laws protect her right to have a therapy per.

The only way to change his behavior is for you to hold him accountable for not paying on time.

Some places have dog walks, gyms, etc....Now for the real logic behind what I'm saying.Jack rented a low priced place, and it has problems, that is why the rent is so low.If that applies to you, you may find that to get something better you have to pay a little more (OR MAYBE NOT).Here's a link that may help you out: https://www.apartments.com/whittier-ca/?

My dog is in dog training with her. 

For example, this yogi dog owning millennial is rehabbing a home in Wheeling, WV. 

I will have to look into that method, already currently own a home with my fiancé and 3 dogs, so I don't know if the renting a room option would work for me.

I buy all kinds of crap (one had dog hoarding and was a total biohazard situation, had to be stripped to the studs and all the subfloor wood sealed) and the worse the situation, the better the spread -- USUALLY.

Habits and changing, and so too will long term behavior and norms related to working from home. 

So just like real estate agents you won't always get paid, even after doing a ton of research, driving, and deal making.It is common to pay "bird dogs" based on a sliding scale, at closing.
