According to my annual salary's assessment that has been made, I was told that I would not be able to live here.
ご質問ありがとうございます。
"The assessment has been made that"を少しrearrangeした文章になりました。
"According to my annual salary's assessment"=「私の年収に関する調査によると」
"that has been made"=「その行われた(調査によると)」
"I was told that"=「私は~だと伝えられました」
"I would not be able to live here."=「私はここには住めないと。」
または、"The assessment has been made regarding my annual salary, and the result was that I will not be able to live here."という文章も使えます。
ご参考になると良いです!
