Fannie Mae's guidelines verbatim are as follows:Must be occupied by the borrower for some portion of the yearMust be suitable for year round occupancyBorrower must have exclusive control over the propertyMust not be rental property or a timeshare arrangement (this has the following disclaimer in the guidelines:  If the lender identifies rental income from the property, the loan is eligible for delivery as a second home as long as the income is not used for qualifying purposes, and all other requirements for second homes are met (including the occupancy requirement above).Cannot be subject to any agreements that give a management firm control over the OCCUPANCY of the propertyThis means that as long as you intend to occupy the property some portion of the year, you could absolutely rent it while you are not using it.
