Its way too much trouble to count out every potential unethical job under the sun because we are all sinners and scumbags come from all walks of life, shapes, sizes, careers, colors and religions.

I have a one page cover sheet I add to each application with check boxes to show that they have the "deal breaker criteria", a section to score the "nice to have" criteria, and a section to briefly explain my acceptance or rejection.Our Criteria: Complete applicationVerifiable rental historySufficient income/resources to pay rent and liveCredit report showing prior addresses consistent with application We do not deny housing for race, color, religion, sex, national origin, handicap, sexual orientation, marital status, or familial status.We do deny housing to individuals:convicted of manufacturing or selling drugsconvicted of a crime the poses a threat to the property or neighborhood, including repeated disturbances, gambling, prostitution, violence, threats of violence, or rapewhere there is poor prior tenancy: evictions, violations, damage to rental property, poorly handled move outs, amounts are still owing to landlords or utilities.who misrepresent information on the rental application

It was pretty dark by the time they finished so I didn't see it until the next day.

My HOA authorized an homeowner to paint his home totally deviating from the color scheme of the neighborhood.

I would have more sympathy for the guy who sat there in the dark because he couldn't afford rent and utilities, than to someone who just decides to steal what they won't pay for (starving people in third-world countries without money stealing food excepted). 

What I mean is, does the sloping lot create a dark interior?  

But, due to the nature of my work I'm very aware of the dark side of human nature and I never allow it in.  

congrats on your journey. in my experience i have refinished hw floors and installed thousands and thousands of square feet of laminate floors. the issue i have found with laminate floors is if they ever require a repair down the road it is unlikely you will be able to get an exact match for the floor you installed  X years ago. hardwood floors can be refinished several times and look great when done right. you assumption on carpet is pretty accurate. we tend to install a mid-grade carpet (not the cheapest carpet available)  and as long as tenant did not totally trash it we have been able to get it cleaned and in some cases even dyed it a different color if we could not get the stains out but yes we replace a lot of carpet after tenants leave. 

My favorite color is GREEN which is also the color I am when it comes to real estate investing.

From some articles I have read though it sounds like exterior upgrades tend to have pretty good ROI, replacing the front door with a nice new steel one in a color that works well with the house, and new siding (or stucco or brick treatment) can be quite a good improvement in the look, that usually has pretty good ROI.
