I believe the behavior will continue to decline.  

I would like a touch screen display and high RAM is necessary for speed. 

Perhaps displaying it in a format like a TD Ameritrade or other investing site.

Inasmuch as Zillow has a checkbox to hide the phone number for the listing, I've checked the box three times in the last month only to have it continue to display.  

His behavior is not shmarmy or unethical at all.

Tenants are supposed to be on their "best behavior" during the application process, putting themselves in the most positive light possible.  

He stated he already has property rented out under that exact system getting $1,500 per bedroom by HASA where tenants use the bedrooms as private living spaces and share the common living space like kitchen bathroom and living room area.The reason I am looking into because I was going to purchase a property very similar to the one displayed above and rent it through this system, and try to snow ball profits into another one and another one, to generate current cash flow and build long term wealth by having HASA pay off mortgage over long term.Do you have any advice on where I could go to do more research or due diligence to see if there is a system out there like this, or to educate my self on the actual HASA program 

If they were a good employee (renter) you would expect them to stop the behavior in question (pet using your property as a toilet) and you would warn them that any damage would come out of their paycheck (security deposit). 

They still may try to deny it, but if I've got dates and times and specific examples, they know that I'm already starting to document a case against them.I have successfully remedied this situation for me with a simple conversation with the tenant, warning them that if the behavior continues it would escalate into written documentation of a violation of their lease, which can potentially lead to eviction.

If they need to change from one service animal to another, then we fill out a new Service Animal Agreement.We also include name and contact information regarding the service animal's veterinarian and emergency care taker.Here is an excerpt from our Service Animal Agreement regarding other terms:"Tenant agrees to:1.Provide proper care for the animal in accordance with veterinary recommendations or ASPCA (American Society for the Prevention of Cruelty to Animals) guidelines.See www.aspca.org.2.Not to leave the animal unattended for any unreasonable periods of time.3.Adhere to local ordinances, including leash, vaccination, and tag/licensing, requirements.4.Clean up after the animal and dispose of animal waste properly and quickly.5.Not to leave animal food or water outside the dwelling, as it could attract other animals.6.Keep the animal from being noisy, aggressive, or from causing any annoyance or discomfort to others.7.Immediately remedy any complaints that arise from animal behavior.8.Immediately pay for any damage, loss, or expense caused to others by the animal.9.Provide animal with regular health care, to include vaccinations as recommended by a veterinarian.10.Arrange for an emergency caretaker for the animal.Tenant agrees to indemnify, hold harmless and defend Landlord against all liability, judgments, expenses (including attorney fees), or claims by third parties for any injury to any person or damage to property caused by Tenant’s animal.Landlord reserves the right to revoke permission to keep the animal should Tenant break this agreement or provide false or misleading information."
