Two homes for the price of one

[Reco Gray]

There is a property for sale for 65k but in the property description it says that in order to buy that house you must buy another property for 45k, which is right next to each other. I'm sure I can talk them down. Are those type of deals worth getting into? Or does it just depend on the condition  of the homes? Essentially I'm looking at It for two homes for 50k each. The outside looks rough, I have not looked at the inside. What should I be concerned about.
