Lending

Hi. I do a little PML.
Let's say I lend someone 50,000 on some terms, could be interest only payments for 12 months, or also principal and interest payments, or just a lump sum payment at the end.

1: How would I create a loan in Zoho Books? Someone suggested that I could create it as an "Fixed Asset"

2: In the case of interest only payments I would think I can record those as "Interest Income"
And when the borrower then pays of the balance - how do I record that.

3: If the payments are principal and interest, how do I record that? As the amount that is principal and interest is different from month to month (Amortization Schedule)

Thanks :)
