Find properties with characteristics that predict they should be selling for 2 standard deviations above what their actual price/value is (or basically just properties that are selling for way below what the model predicts they should sell for).The challenge here is of course step 3.

What does the law say about emotional support animals?

I even noticed the tenants had affixed some kind of bird cage to the outside of the home to allow an animal to go in and out of the home.

Identify areas with characteristics that will drive demand....accessibility, good schools, neighborhood amenities that improve quality of life (parks & recreation), quality retail/commercial etc. 

The location defines all long-term income characteristics, including whether your rents keep pace with inflation, the total capital required to acquire sufficient properties to maintain your standard of living, and how long your income will last.There is a straightforward location selection process.

STR and MTR investing is a different animal all together taking you from housing to hospitality and requires more of a time suck than many initially realize. i personally only do long term rentals and students. i do have a property in mind and making the connections to transition it into a sober living home. excited to see how that shakes out. 

Call animal control and report an agressive dog 

Humans cats and dogs, goldfish, tweety birds, not horses or other farm animals of any type.

Animal control was called, and I decided to issue a 10-day notice for the tenant to remove the dog.The tenant with the dog is now upset because they want to make things right with the injured tenant, who is refusing to have any contact with them.

The hold harmless agreement is another animal in itself.
