I'm not an expert but from the pictures the garage addition looks sketchy. Plus the roof, to me, looks iffy. IT looks fine but there is a line that bothers me.
Go to the town hall and review the building permits. That garage might not be legal.
The kitchen looks ok, looks like they did their best with little money.
From the reflection of the house it looks like the owners don't have much money but might have tried to make the house some what decent. The living room is their saving grace though the floor might be laminate.
Get it inspected with great attention the foundation, mold, and water drainage around the house. Also stucco can hide some huge problems.
I just get the feeling that the house might be damp with creates a mold problem.
Just my thoughts.
