They estimate 3+ weeks until electricity is restored, so generators are making the trip. 

But despite those numbers, it sounds like you're just trying to force this one to work by massaging it a bit - which is usually an indication that you should move on.

You need a signed lease and security deposit, and the lease starts when they take possession (which is the day you give them keys, whether to move in, prepare for him, or just store a box.More important to the lease, you need to make sure that you clarify terms about altering the property, and having it restored upon him move out. 

Early on I started out with a 20 unit multiple property C-class seller financed deal and it almost bankrupt me as I didn't do my analysis correctly.It's great that the seller is willing to hold paper but be sure you aren't massaging the numbers to create a better deal than what's really there and be especially certain you have sufficient cash reserves to tackle a project of that size even if it's 100% financed.  

Most restoration companies are able to do that, I believe ServPro is nationwide and likely in your area.

I was surprised by this interpretation and politley explained that she would be billed in full for all costs to restore apartment to previous condition and the security deposit was different.

As a bit of background I am a developer AND a builder specializing in historic restoration and new construction urban infill.

Historic homes are different and the right renovation/restoration will get much more money from the right buyer.

If there are no problems with your roof deck and no signs of other issues with your roof’s structure other than worn or damaged roofing materials, a roof restoration or overlay may be recommended.

NEVER AGAIN, but I have learned a lot & massaging them is akin to poking a sleeping dragon.
