I am at a point of almost cutting even (depending on the final value which I don't now yet, he only said it was under contract) or loosing money on a deal I've been in for about 9-10 months.Thank you all in advance!

The slab is in stock, just needs to be picked up, cut, and installed. 

And I do not know if this includes grass cutting or snow plowing, but that is the same thing.

No matter what floor you put down over concrete, it will expand and contract a lot. i had one project recently, i put down a floating floor and left 1/4" space all around, only for it to swell up enough that it buckled and i had to pull the shoe molding off and re cut  the floor even more so it could sit back down, that's how much it expanded. if the floor is in a basement make sure it is rated for below grade and can be used on top of concrete.

It would be much more cut and dry if I had a home on a lot, but really limits my market.

If they do, you can cut them a check and dismiss the case before it ever gets to court, until that time they can pound sand!

Instead of sharing cash flow proceeds I would recommend offering a guaranteed IRR (for which you are personally responsible) and potentially a cut of the equity in the property. 

In the past, I have employed them through recommendation from my acquaintance or neighbors or just through yelp but the current tenant is a little bit "sensitive" (paying rent timely and not trashing the place so no big deal so far) and has repelled many of the repairmen that I have used in the past as "unprofessional" (they can definitely get the job done/fix the problem but the tenant will dispute with them for e.g. being late, not good at communication, or "cutting corners").

We had wired the whole house, that night it got all cut out.

There are new pre-fab firms doing exciting stuff with innovative designs:http://methodhomes.net/http://www.projectfrog.com/There seem to be a lot of benefits such as building in a controlled environment, cutting down construction time (which mean getting to market faster, lower construction loan interest, etc.), faster permitting.
