So what's causing the delay? It seems that a mix of generational preferences and economic circumstances is responsible. Across the nation renting is actually about 38 percent more expensive than purchasing a home, according to Trulia, a real-estate search-and-analysis site. Right now rates on mortgages are low. Very low. And though home values are rising, properties in many places across the country have yet to return to their pre-recession prices. That means that the cost of buying in many areas is relatively affordable, which is especially important for first time buyers who won’t have the proceeds from property sales to finance their purchase.

Even in New York and California where homes in major metropolitan areas can be particularly pricey, the spread between renting and buying is small thanks to few rental vacancies and skyrocketing rental prices. “What I'm paying for my mortgage is less than what I was paying in rent,” says Yasmine Parrish, a 28-year-old PR-and-marketing professional who recently purchased a home in Los Angeles. Parrish's mortgage broker helped her find a program for first-time buyers that allowed her to put down 5 percent instead of the standard 20 percent. Without a low down-payment option Parrish says she would have eventually reached her goal of owning a home, but saving up for it would’ve taken at least another year or two and by then, it’s likely that prices would have risen.

So why aren’t all young would-be homebuyers just taking advantage of the low down-payment options offered by these plans to get into the market before prices rise further? Not everyone has access to the programs that can shrink a down payment, and even for those who do, such help may not be enough. “Typically the down payment is the biggest hurdle for a homebuyer” says Ken Fears, director of regional economics and housing finance at the National Association of Realtors. “Programs that have a lower down payment are going to provide a bigger boost for the consumer.” Some programs, like Fannie Mae’s Community Home Buyer’s, require a 5 percent down payment, a sum that still makes saving a difficult proposition for many young people, particularly those in areas with quickly climbing home prices, such as San Francisco and San Diego. States like North Carolina and New Hampshire, have particularly well-regarded programs that allow for down payments of about 3 percent. Some private lenders also offer assistance to new homebuyers, but fees and additional factors, such as debt-to-income ratios, can prove more restrictive.

But programs aimed at reducing down payments for first-time homebuyers can feel like a double-edged sword. In competitive areas, where homes are scarce and multiple bids are common, an affordably low down payment can be limiting. “You're not very competitive. If you're going into a house with multiple offers and they see 3 percent down versus 10 or 20 percent down, they're not going to go with your offer,” says Anne Simpson, a 27-year-old teacher and prospective homebuyer in Washington D.C.
