Or do we need to fly up there and get a hotel and have to supervise this in person as far as interviewing contractors, etc.?  

I would advise against doing this for a multitude of reasons and if the seller runs this by their lawyer there is no way is will fly.

You will have to fly to another state at least three times, you will have to pay attorney three times, you will have three roofs to fix, the list goes on.

Having a warm place to fly off to at a moment's notice as long as it's not rented at the time, as well as a great place to hang out and travel FROM.

Don't bother with an LLC for that property, it won't fly.  

It may or may not be necessary to meet up in person but I find getting involved and flying out to join the local real estate investor meetings has worked well also.

It wont fly , the city wants its tax revenue .  

Then their is the gigantic apartment for sale on Carroll but that is a no fly zone for me.Combine this with my post from the other thread on too much A-Class inventory coming on line right now and I think it would be wise to really sit down and figure out real exposure to risk before buying any multifamily around downtown or Notre Dame right now.Edit: The above was super negative!

It also allows me to change assumptions on the fly. 

Maybe you can try some of those sticky fly traps and a strong insect fogger.
