It might be worth offering to take care of any remaining items in the house after they've cleared out the items of value they want from the house.  

You will have extra expenses on things like taxes and other items you did not expect but as you add properties those costs will drop per property as they tend to be static.

2) Is it possible to structure this deal different so i don't have to get traditional financing?

At that point you would have three items 1) your adjusted basis 2) your depreciation recapture (25% tax IIRC) 3) your gain (taxed at 15-20% IIRC).Your basis throughout the years will change as you decrease it by taking depreciation, and increase it when you perform improvements which will then be depreciated.

@Colleen F.has posted some items to consider with respect to consideration for the occupants. 

Each year, after I purchase a property, I have to re-look up how to treat the various items from the HUD-1 (closing statement) when preparing my Schedule E.

QuickBooks Pro has a Fixed Asset Items List, which allows you to enter in everything you want to know about your rental property.QuickBooks has been around a long time, is in the stores just about everywhere, and is sold at reasonable price, plus it grows with you.Nancy Neville

These items are what keeping me from using it exclusively on my iPhone.

For fix and flips, I would assume you would need to be around the same rate as a traditional HML, unless you are willing to adjust your risk outside of what they offer. 

I've lost 2 great investment opportunities because the traditional financing process has been so slow
