It looks like that only applies if the loan was issued in the course of business. The person I borrowed from is not in a related business, nor are lender.
"Not in the lending business.
If you receive mortgage interest of $600 or more in the course of your trade or business, you are subject to the requirement to file Form 1098, even if you are not in the business of lending money. For example, if you are a real estate developer and you provide financing to an individual to buy a home in your subdivision, and that home is security for the financing, you are subject to this reporting requirement. However, if you are a physician not engaged in any other business and you lend money to an individual to buy your home, you are not subject to this reporting requirement because you did not receive the interest in the course of your trade or business as a physician."
