In my experience, true change only occurs when people get to a point where their level of discomfort tips the scales, i.e.

Never did I receive a phone call about the seller going to a hospital, nor did I receive a phone call about discomfort.

Base it on your risk level discomfort level.  

It took getting over the initial discomfort of enforcing our rental agreement. 

The purpose of this post was not to bash any aspect of the industry but rather to help me as I figure out if my discouragement lately is out of temporary discomfort with a new field or if this niche is just NOT for me.

I don't see that good of a return on 120K houses when I run the numbers most of the time, but I have less experience than John and would not argue with him about what good price points are around here.As far as your discomfort with loans, it will take you, in all reality, at least 3 years to get 5 loans unless you have an extremely high income and do not need to count rental income for your DTI ratios.

It would just lead to discomfort if you acted on your own using the dog as an excuse, in reality, look for another valid reason if you don't want to do business with them.BTW, Pits aren't bad dogs, the owners are bad owners.

@Victor Sprague risk future discomfort and possibly giving the two other tenants a reason to leave is not the worth the risk.

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."

,I'm of the opinion that you are experiencing some level of discomfort in making a decision about your tenant situation.
