If we are making a commercial loan to purchase an office building that also has a residence attached that our customer indents to occupy, is this HMDA reportable as a home purchase?

OSC to 203.2(h):
2. Mixed-use property. A dwelling-secured loan to purchase property used primarily for residential purposes (for example, an apartment building containing a convenience store) is a home purchase loan. An institution may use any reasonable standard to determine the primary use of the property, such as by square footage or by the income generated. An institution may select the standard to apply on a case-by-case basis.

thanks for the reference, much appreciated.
