Normal wear or potential risk? 1960s apartment

During inspection today I notice the outer brick wall has cracks on it and some of the inside walls have small lines on it. I note the vendor (owner builder) freshly paint the apartment thus I want to know if he is covering some problems or not. Please see attached photos for the small lines and cracks.

This is a 1967 apartment block, apartment is on the second floor in the corner.

Reason I ask is that cracks on outside brick wall can mean foundation problem and these would need underpinning to resolve the problem which is expensive.

Thanks in advance.

 

From your description and accurate aging of the building, I would hazard a guess and say that the building is at the end of its useful life (50 years), has no further depreciation left in it and should be demolished as it is probably quite ugly.

The external crack is likely to have been caused by brick growth and a lack of articulation joints at the corners of the building.

 

Many people say depreciation is great benefit to the investor but reality is depreciation is the gradual decline of both the physical and economic life of building
Scott No Mate is correct this building is at the end of its life!
