Structural issues possible cost evaluation

[Jessica Kirby]

Goodmorning, we just received our inspection report back on a home we thought only needed upgrades. There appears to be a substantial amount of issues. Most I'm comfortable with however the structural issues do scare me. I read through many other posts but stil do not feel confident. I am wondering if anyone experienced would be able to provide feedback on how deep this repair could go. The joist have been cut and are cracked as well as substantial mold. I do have photos I  as well as a more detailed description. There are multiple places with cracked brick on exterior as well. I was given a 10k-12k repair unofficial estimate and want to see if others feel this may be reasonable and what else could this lead to cost wise that may not be realized at this point. Thank you in advance .
