Of course there are unique challenges that arise, but over time the marketplace will work out the kinks and develop best practices.

Creative financing, being able to see a neighborhood before it arrives, unique approaches to structuring deals etc.    

I could use any help I can get.It's a unique property, as it is in a older, established neighborhood.

Our most recent lease up (a unit in a 1976 duplex) was attractive to the tenant because she said "I like it because it's not modern and it has unique character!"

I know what you mean having a unique property when time to sell.  

And let them deal with you very specifically on your unique situation.  

I have become so numb to DC and MD's narrow structures; It blends in as  NOT so unique anymore! 

. :-)But just wanted to point out the assessment thing being more unique to Cali.

I'd be looking for an ugly corner lot or high visibility lot where you can make an exterior  visual impact to the neighborhood, a block where you can target getting multiple properties to have more influence on a black rather than a neighborhood, and/or a property with something unique to set it apart (garage, extra bathroom, bedroom, etc) and attract a better tenant who will improve the neighborhood.  

The options for financing will depend on your unique situation so you'd want to connect with a lender to understand those options.
