Thanks again! There is no easy way to tell specifically what the loan was used for. According to the owner, the loan was used to "run" the company. Bookkeeping prior to 2020 was sketchy. Because of the amount of the loan compared to total expenses, and the existence of other debt, the loan was probably used for all of the above, except payroll. There is no payroll. 

The business property is a separate location from home.

I think 1098 was issued because the property securing the loan is individually owned and the loan was also in the name of the individual.
