With a requirement that all this documentation be reviewed by a third party, adding to the costs of the project.

Every one of these transactions you generate through marketing should eventually lead to one or two more through referrals and just general exposure to your market, and that part is largely free of charge. 

No gimmick, no needing to pay a 3rd party to manage this, no trickery involving the notion that there are 4 weeks in a month (there aren't) and some mystical magic about biweekly payments. 

I don't plan on having any further contact with the tenant personally.I may give him an offer through a third party that if his stuff is removed I will let him out of his lease, but I don't really want him back on the property to retrieve his belongings.

There is a monthly meet up in Lake Forest on the third Wednesday (Tomorrow) of each month at 7:00.

Sorry to kind of ramble but what I'm getting at is, does the cost of this mess get eaten by myself or am i able to go after one of the other 2 parties for neglecting to inform me of an issue.

I save a third of its cost, so my return is over 15% a year at worst, and 33% at best. 

It has a lot of vacancies, about a third, which affects the numbers of income/expenses.I'm mostly learning how to analyze this since it's over my budget, so don't stress out over me buying this.

The hard part is factoring in the time to acquire 100 doors on your own.
