Investors can purchase a whole note or a partial note from a note seller. A whole note purchase is when the investor purchases all of the remaining payments on the note. A partial note purchase is when the investor purchases only a portion of the remaining note payments. For example, if a note has 20 years worth of payments left, a partial purchase may include only the next ten years of payments. The number of payments purchased affects the resulting yield on the investment. After the partial term ends, the payments revert to the original note seller.
