"For home improvement loans you report the property and its occupancy status being improved. If multiple properties you have the same options to report all or one, but if only one it must be the property being improved." - from Weekly Banker Briefing

My question is, If the home being improved does not secure the loan but another dwelling does, then the property type, occupancy, and property location will be for the property being improved and never the property securing the loan. Right?

correct.
