From what I understand, the most common are related to automobile accidents (boy my neck hurts...).

I done it all by accident.

It is best that you have a system where the contractor signs a daily logbook, that will help a lot of compliance requirements or litigations, particularly with payments too.If they bring somebody and accidents happen, its their cargo (hence, if you are the GC, you are the boss, same goes for sub), be sure to put your caution tapes, or its going to be a grey area.

You hired a contractor who doesn't know what he's doing, or forgot to include something important and will come to you with a change order/increase request when he realizes.3.Your signed contract needs to include a complete scope of work, and a predetermined rate for unexpected but needed extra work. i.e.

SDIRA investors will commonly plan and strategize for all expected and unexpected events to determine their cash balance requirements.

Not saying your mother would do that but when money is involved unexpected things can happen.

There are expenses and unexpected happenings in any business.

Looks like it was a great success even with the unexpected issues to overcome.  

This is what makes investing such a fund time ::sarcasm:: but truly these same issues are what keeps people out of this investing arena.But i think this is why you have to plan as much as you can for the unexpected, repairs, maintenance and unforseen expenses have to be part of your analysis.  

Overpaying is definitely not a concern, the only way it would bite me was if it condemned because of something unexpected.
