1098 vs 1099-INT - Which one should I use

[Dave S.]

The setup is as follows: I loaned someone money. He used this money for flipping a house. He paid me 1% a month until a balloon payment +3%. At the end of the year, his CPA issued me a 1099-MISC form. Obviously this was not correct. Im being told that I should of sent him a 1098 form. Should I of done the 1098 form or should his CPA resolve this by sending me a 1099-INT??? Looking for what others think
