Hello Cerwin, from my experience you are going to have a tough time finding a 2-4 unit property in Syracuse in that price range that doesn't need some serious TLC, and the taxes are going to be in the $3-$4k per year neighborhood regardless of what area of town you are in.
You might try making your purchase offer on a place contingent on having the roof be properly repaired prior to purchase. That would satisfy your mortgage guy, unfortunately the type of owner who would let their property get so run down is the same type of owner who you probably wouldn't want in charge of a roof repair.
You could try talking to the Landbank folks directly, they might have ideas on how to navigate their property lists. They might even be convinced to go through with a foreclosure if they had a buyer lined up. Again I fear you will have a hard time finding a place from the land bank that needs less than $15k in work.
If you plan to actually screen your tenants and manage your property well you are welcome to buy in my neighborhood.
