I am not sure, it seems to be a combination. The FHA requires the homeowner to be 62 or older for an FHA reverse mortgage. I have never seen a private reverse mortgage advertised, but apparently they exist and from what I have read online, are offereed to those as young as 55- but apparently are marketed to those with fairly expensive homes.
(However, it might still be a vote winner. Voters aren't exactly the brightest.)
