I've found that when I get to a point in research on one aspect where the info starts piling up, I just move on to the next item on my list.

I will start going through the different items you listed.

She told me she is not aware of any law that requires contractors to list an itemized audit of material labor costs.

Line item bid, non-binding, different columns for materials and labor.

If you can show me you have both an itemized list of repairs (with costs) and 3 recent APPLICABLE comps, you will gain a ton of credibility.

Try not to lose sight of the fact that with a few exceptions (e.g. baby in the car) it is the total picture not any one item that should give you pause in renting to someone.

All the items purchased there run through the LAR account which requires project name and signature as well.

Items such as hardware, outlet covers, light fixtures, caulking, window blinds, painting supplies, etc.

I don't want this to continue happening and set the precedence that we don't enforce what is written in the lease and then have her think this is the way it is and she can do that in the future too with rent or other items.

It appears there are still many items in the home, yet we truly can not tell if she has been home.We think she may have just left and left most of her furniture as the items are really not much to speak of as far as quality or value.Do we go to court to evict someone that is not there?
