A doctor’s letter does not turn an animal into a service animal.While Emotional Support Animals or Comfort Animals are often used as part of a medical treatment plan as therapy animals, they are not considered service animals under the ADA.

Hey @Joshua Dorkin can we block or ignore certain users?  

We currently live in the east side and it is really block by block.

I would also hand them our "Rent Past Due" letter which outlines what they need to do and the timeframe for doing so. 

I recently sent out 4 letters to the owners of 4 to 20 unit apartment complex owners.

Try creating a letter introducing yourself and explaining that you are ready and able to buy quickly if they would consider selling and leave it at the door. 

My original plan was to send letters to each of these people using yellow letters, but when I  went to purchase the post cards it seemed like I had to input the property information manually.

I wouldn't waste my time until they have a letter of qualification from their lender. 

Then ended up having to pour a 12" concrete wall against the original block, adding and additional $7000 to my rehab. 

I would say within the last 15 years this has been the trend, on a block there are typically 2 or 3 homes being rebuilt.
