@Harry Case -- to find non-owner occupied properties, you can either team up with a real estate agent who can pull that sort of information for you, or you can use a service like Property Radar to pull this kind of information yourself.

I usually connect my investors with my contractor or inspector to walk through the property so that everything can be sorted out in one go, or I have my clients make an offer subject to a walkthrough, allowing us to get the ball rolling.

He used this experience to motivate him in his work and be grateful for the opportunity he had. 

Most of our rental properties have a dining room or some sort of dining area.

I have researched, bought, and used all sorts of products to test effectiveness.

Not sure how Las Vegas operates but when I get a code violation of any sort I get certified mail delivered to my personal house and multiple other regular mail attempts. 

Neither buyers nor sellers are that motivated. 

However, I could see that changing in the next 18-36 months, and as someone else mentioned, maybe you are able to get some sort of a discount today and in 3-4 years you look like a genius. 

Refusing to rent due to source of income I am sort of OK with and understand.

Since you are taking on additional liability having tenants in place, you're probably going to want to update your insurance policy and put some sort of asset protection in place - most people use an LLC for a small portfolio.
