or the emotional costs?

I am mentally prepared to lose money as that is a risk of investment and it may all work out in the end but it has been a roller coaster of emotions!  

Here are a few links to help you out. https://www.ada.gov/service_animals_2010.htmhttps://adata.org/publication/service-animals-booklethttp://www.humanesociety.org/animals/resources/tips/assistance-animals-tenants-rights.htmlhttps://www.biggerpockets.com/renewsblog/2015/03/11/emotional-support-animals-waiver-no-petpolicieslaw-say/

Nothing was signed and there are no legal remedies involved this early in the process, so no harm done should things not work out.It's not fool-proof but it's less risky than most other aspects of REI  There is the rub...YOU may one that isn't hurt but, putting a homeowner through the emotional ringer with your assertions that you are going to save them from foreclosure, put money in their pocket, and increase their credit (Your quotes, not mine) as a selling point, only to back out if your interests wane somewhere in the process, will cause harm.I'm guessing the property must not be in New York or other areas of the state that require you to be a licensed foreclosure avoidance consultant or that, you have a written contract before any consulting services can be rendered (You did say you have nothing in writing if I read correctly).

Does this mean, for example, I can turn down anyone with a pet regardless of it being an "emotional support animal" if we do not outwardly advertise? 

I suggest you remember that maintaining a rental property is a business as well and your emotions should be separated is such transactions.

Even though it sounds like a few tough (assuming emotional) weeks of negotiations, I encourage you to stick to your investing criteria and if something during due diligence doesn't hit your marks, pass on it and start looking for the next one. 

I've also read on forums that the customer service is super limited with this method, by email only, so no personal touch at all, which obviously, is the cornerstone of a real estate agent's value, along with their knowledge and expertise of their local market.The day we can take emotions out of selling or buying real estate is the day realtors will cease to exist.

#Scottsdale Emotional and physical well being: (We have plenty of bars and that doesn't do it we have plenty of events with drinks)Income and employment: Depends on what you do, but Real Estate is not on par with the majority of the income earned hereCommunity and environment: (We have plenty of bars and that doesn't do it we have plenty of events with drinks)Like others have said take it with a grain of salt.....Like living in Scottsdale and the above is a joke if some of you don't get it :)

Well, there are a few different ways to do this, with each way being a better fit depending on multiple variables such as risk tolerance, available time to run a project, the interest in running the project, and emotional grit.
