It is my opinion that in Blink Gladwell's theory and thesis is flawed in attributing superior results to having less information to work with.

Take sometime to search around the site and see what great information you can uncover.

I personally am not a fan of the turnkey model (here or anywhere else) as I think it has some serious flaws (not to be rehashed here).  

IF you did not occupy subject you may not have known whatever they uncovered. 

There are many guys on here with more experience than me so they can point out the flaw in my suggestion, but I would get your 30-day notice in writing ready, then personally deliver it right after she pays her September rent if you really think she will pay it, but then suggest that if she moves out more quickly, like in 2 weeks, you'll meet her, make sure the house is in proper order, and give her a check for her security deposit right then, minus any rent she still owes for October.

Now if you had a workers comp policy, then you would end up covering any worker you hire; a year end audit would uncover that you had employed workers who did not carry their own coverage and so you would be paying additional premiums for the time (and tasks) that they worked for you!  

It wouldn't be the first time a short sale participant had a flawed view of what they think should happen in a short sale transaction.just my two cents...

@Max TanenbaumI think that is an interesting idea but has some flaws. 

Doing proper due diligence will definitely help find some issues that may have been unforeseen, but I don't think there is a way to uncover every little thing and do a full transfer of knowledge from the seller to the buyer (especially if it's been with the seller for a while).

If they are injured and claim Workers Compensation (yes it happened), you could end up with an uncovered loss.
