According to Trulia’s last Rent vs. Buy report, buying remains cheaper than renting nationally. Indeed, for Millennials, buying is an average of 23% cheaper than renting. And buying continues to be cheaper in 98 of the 100 largest U.S. metro areas, according to Trulia.

But that’s not the perception, according to Freddie’s study. And even renters who said they planned to buy in the next three years said they faced significant hurdles, most notably affording a down payment, credit history, insufficient income and carrying too much debt.
