I am considering investing in a multi which is actually one large house split into two identical three bed apartments. 

Now, go buy the identical one for sale next door for $600k.

This isn't standard for the neighborhood - most duplexes are almost identical on each side.  

LOTS of these frauds would be sued for that.

Hello all!I like the idea of keeping my personal name out of the mix as much as possible.  This is not because I plan on being a bad landlord.  It is because I know there are crazies in the world, and I do not want to...

"Rarely seen such blazen fraud..." ouch...thanks for the head's up Michaela

Although you don't mean to do it, you will be committing fraud.  

You can pull out of the deal , but they will keep it unless you have proof they deliberately hid information about the property from you with the intention of fraud.

Since index funds are designed to mimic, as closely as possible, the index they track, it would seem obvious that they should all have very low expenses and fees, if not identical costs for identical returns.

There's obviously been a lot of mortgage fraud in the past 10 years where people took advantage of this sort of stuff and didn't actually move in to the property so I don't want you to be thrown in such a bind.
