Attachment of other real estate in event of foreclosure?

[N/A N/A]

If an owner were to go through the foreclosure process on some real estate that he were upside-down on (had no or negative equity), could the lender attach or lien other real estate or liquid assets he owns, especially if those assets were in other states? If so, how often does a lender attempt to recoup their losses in the case where the owner does have real estate in another state and liquid assets? Thanks!
