@Kenneth Jenkins you forgot to mention owners that expect a PMC to use contractors off Craigslist that are unlicensed, NOT insured and rarely have acceptable experience/skill - but, they quote the "best" price.These same owners will sue a PMC if using these types of contractors results in a tenant lawsuit.

I find it disturbing how many "business models" are all about suckering people into buying and even use skillful wording to deceive people into signing up.

Poor personal finance skills.
