With the increase in supplies came a return of all-cash investors, who had been moving out of the market, causing sales of homes on the low end to plummet. Investors made up 22% of home buyers in February, according to the Realtors, up from 19% in January. All-cash sales hit 32%, up from 28%, and distressed home sales also increased to 25% of all sales, from 23%.
Low inventory has kept first-time home buyers, who largely seek lower-priced homes, out of the market. Newlyweds Brian and Ali Earle have been looking for a home in Northern Virginia for almost a year.
"There's not a lot out there," Brian said. "It's actually amazing. We see houses go under contract in a day or two, and so we really have to be on top of the game and be willing to drop everything and run and go check out a house, or it'll be gone."
Brian and Ali are qualified for a mortgage, but many sellers today still favor the all-cash deal. That puts them at even more of a disadvantage.
"Everywhere we've looked there are at least five or six offers going in within a 48 hour period," Ali said. "It's a little stressful."
Faced with competition from cash-heavy investors for, first-timers represented just 30% of buyers in February, compared to a more normal 40% historically.
