That's according to a recent survey of 2,000 current non-homeowners, only 53 percent of whom are confident in any way that they'll be able to own their own home someday.

In addition to the 40 percent who think hitting a jackpot is their best chance at home ownership, one in four (26%) believe they'd need to inherit money from someone in order to ever own a home. One in five (19%) even believe they'd have to marry someone rich.

Overall, the average American thinks it would take them between three and four years to afford a home – and a third believe it would take them five years or more. Another 20 percent expect that they'll never be able to afford one.

Conducted by OnePoll on behalf of Divvy Homes, the survey also revealed that almost six in 10 (57%) non-homeowners would find it difficult to afford a house in their current neighborhood. Despite that, 67 percent are still hopeful about the possibility of one day owning a home – more than five times as many as the number of people who actively described themselves as hopeless (12%). Another 19 percent describe themselves as frustrated and 11 percent feel desperate.
