Major foundation problems in a 43k home (buffalo ny)

[Diana K.]

I was just informed by my newly hired property management company that I have major foundation issues at one of my properties (walls starting to cave in and bow inwards, according to their report).  The price I was quoted to fix this issue was 11k. This is my entire down payment for the home which was bought 2 years ago.  

So here are my concerns... Why was this not found during the inspection? Could this really happen in 2 years in a  100 year old home? Is it worth it to do this repair and if not what's the alternative? Welcoming all input especially from property owners in Buffalo Ny.
