Multiple Parcels Requirements
Each parcel must be conveyed in its entirety.
Parcels must be adjoined to the other, unless they comply with the following exception. Parcels that
otherwise would be adjoined, but are divided by a road, are acceptable if the parcel without a
residence is a non-buildable lot (for example, waterfront properties where the parcel without the
residence provides access to the water). Evidence that the lot is non-buildable must be included in
the loan file.
Each parcel must have the same basic zoning (for example, residential, agricultural).
The entire property may contain only one dwelling unit. Limited additional non-residential
improvements, such as a garage, are acceptable. For example, the adjoining parcel may not have an
additional dwelling unit. An improvement that has been built across lot lines is acceptable. For
example, a home built across both parcels where the lot line runs under the home is acceptable.
The mortgage must be a valid first lien that covers each parcel.
