If you've got a slob in one unit and an inside smoker in the other, then you'll have a hard time attracting good tenants when one or the other moves out.If you don't want to fix the problems, then you should expect them to get worse.  

Would this type of property be attractive for a Turn Key Buyer?

(which would be really a stretch)  Or a down payment on a house and another income producing asset.  

Yes, we would absolutely have to sell to an investorI am concerned though,  because I have read that it would be hard to get a loan on a non producing property, so basically we would need a cash buyer...That definitely narrows down our pool of potential buyers..

An investor I know said that my best bet would be to attract a good set of trustworthy investors and require a fee whenever I make a real estate connection.

I personally like income producing assets.  

The idea of eventually owning multiple properties that produce a steady cash flow is extremely appealing, however, I understand that I have A LOT to learn. 

I think if you run the numbers on the deal above with financing you will see that the return is actually pretty attractive.

Vacant homes are frequently broken in to and attract squatters and unsavory characters.

It is a decent income producer.
