<human>: Hi all, 

I was approved for a mortgage, found a house, made an offer, offer was accepted, yadayadayada. My mortgage company is doing their paperwork & asked me for some additional documents. One of these included a "consumer explanation report" which they forgot to attach to the email they sent. 

While I'm waiting on them to send me that, I'm wondering what it is? He said I have to provide a brief explanation for each line item and then sign/date the last page. I let him know that he mistakenly didn't attach it, but I've noticed he's very slow to get back to me. 

Google did not provide me any information in their search results :/

Give me the gist of the text in a nutshell
