We did a loan using two rental properties for collateral. How do I determine which property location information to use on the LAR?

Assuming it is HMDA reportable, you would follow the instructions in the HMDA Getting it Right Guide. Search the guide on "multiple properties" and you will find the instructions below.

For a purchase:

"Property location—multiple properties
(home purchase/refinance
of home purchase). For a home
purchase loan, an institution reports
the property taken as security. If an
institution takes more than one property
as security, the institution reports
the location of the property being purchased
if there is just one. If the loan
is to purchase multiple properties and
is secured by multiple properties, the
institution reports the location of one
of the properties or reports the loan
using multiple entries on its HMDA/
LAR (with unique identifiers) and allocating
the loan amount among the
properties."

"Property location—multiple
properties (home improvement/
refinance of home improvement).
For a home improvement loan, an
institution reports the property being
improved. If more than one property is
being improved, the institution reports
the location of one of the properties or
reports the loan using multiple entries
on its HMDA/LAR (with unique identfiers)
and allocating the loan amount
among the properties.
