"In the case of a taxpayer using more than one property as a residence, whether property is used by the taxpayer as the taxpayer’s principal residence depends upon all the facts and circumstances. If a taxpayer alternates between 2 properties, the property that the taxpayer uses a majority of the time during the year ordinarily will be considered the taxpayer’s principal residence. In addition to the taxpayer's use of the property, relevant factors in determining a taxpayer's principal residence, include, but are not limited to - (i) The taxpayer's place of employment; (ii) The principal place of abode of the taxpayer's family members; (iii) The address listed on the taxpayer's federal and state tax returns, driver's license, automobile registration, and voter registration card; (iv) The taxpayer's mailing address for bills and correspondence; (v) The location of the taxpayer's banks; and (vi) The location of religious organizations and recreational clubs with which the taxpayer is affiliated."
