Welcome to the ‘nepo’ housing market: 40% of homebuyers under 30 get family money to cover their down payment

There’s this consensus that people who come from money are at an advantage, Redfin’s chief economist, Daryl Fairweather, explained—but it made her think: how does family money play out in the housing market, she told Fortune.

Redfin conducted a survey of recent movers earlier this year, and found that 38% of more than 500 buyers under the age of 30 either used a cash gift from a family member or an inheritance to afford their down payment, making them what Fairweather calls, “nepo-homebuyers” (clearly a play on nepotism—giving power/favors to relatives), which she’d recently written about as a Forbes contributor.

“I think the reason that matters so much in this housing market is because of how expensive housing has become,” Fairweather told Fortune. “It seems like the only way to kind of get your foot in the door to the housing market is to have some help,” or have an exceptionally high-income, particularly at a younger age, she added.

Housing affordability is deteriorating, and it’s worse now than at the height of the housing bubble, following an over 40% increase in home prices coupled with mortgage rates that have more than doubled. For many, homeownership is becoming out of reach. If you were looking to buy in California, where the average home value is $741,789, to put 20% down you’d need $148,358. Let’s say you were looking to buy in Texas, which is much more affordable than California, with an average home value of $301,763, you’d still need $60,353 for a 20% down payment. For some, that’s not feasible, and it doesn’t take into account what would be a substantially larger monthly mortgage payment now that mortgage rates are back up.

“If you’re trying to get into the housing market, and because of how high interest rates are, because of how high home prices are, you have to be like the exception to the rule in terms of your earnings to get into the housing market if you don’t come with cash,” Fairweather said, and that cash typically comes from parents or other family members.

At the same time, the income needed to buy a starter home as a first-time homebuyer is higher than it used to be, given that it jumped 13% in the last year alone, Fairweather explained, citing a recent Redfin analysis. So it’s clear, family money can make the difference. And, the earlier you can buy a home, the more equity you can build—which let’s say in the case of a starter home, can help you buy your next, maybe forever home.

“It really kind of turns into a snowball effect, where the people who are getting help, the earliest, end up accumulating even more wealth, and it further solidifies that divide between the haves and the have-nots and perpetuates intergenerational wealth inequality,” Fairweather said.
