I think you are confusing some numbers here. The mean number of income collections before a building breaks down is not 7.236, but it is 100%/7.236%=13.82.

So for your example this would mean 13.82*2,400=33,178, which means a profit of (33,178-15,000)/13.82=1,314 per income collection on lvl0. For lvl5 this is ((13.82*4,827)-37,327)/13.82=2,126 per income collection.

Is this explanation satisfactory? Please let me know if it isn't and I'll try to improve it.
