The boom and bust in housing over the past nine years is still casting a shadow over the housing market, according to the formal 2015 forecast from Trulia (TRLA), and while five major measures of housing’s health are not back to normal, three are getting close.

“The rebound effect drove the recovery after the bust, but is now fading. Prices are no longer significantly undervalued and investor demand is falling,” says Jed Kolko, chief economist for Trulia and author of the forecast. “Ideally, strong economic and demographic fundamentals like job growth and household formation would take up the slack. But the virtuous cycle of gains in jobs and housing is relatively weak, and that will slow the recovery in 2015. All the same, consumers are optimistic.”

Trulia’s forecast predicts that in 2015, more markets will settle back into their long-term housing patterns. They note that even the markets that have been slowest to recover and have struggled longest are seeing foreclosure inventories decline and the sales mix moving back toward normal.

“At the same time, first-time homeownership, single-family starts, and new home sales won’t come close to fully recovering in 2015,” Kolko predicts. “But if 2015 brings strong job growth, big income gains, and the long-awaited jump in household formation, then 2016 could be the year when we see a major turnaround in homeownership and single-family construction.”

Trulia notes that the housing market increasingly depends on fundamentals such as job growth, rising incomes, and more household formation.

“But here’s the hitch: These fundamental drivers of supply and demand haven’t returned to full strength. They aren’t able to fully take the reins from the rebound effect,” Kolko says. “Importantly, the share of young adults with jobs is still less than halfway back to normal, many young adults are still living with their parents, and income growth is sluggish. This points to a tricky handoff, and means housing activity in 2015 might disappoint by some measures, though the rental market will remain vigorous.”

Here are Trulia’s three takeaways for 2015:

1. Price gains slow, but affordability worsens.

Price gains slowed in 2014 and we’ll see more of the same in 2015. In October 2014, prices increased 6.4% year-over-year, down from 10.6% in October 2013. The slowdown has been especially sharp in metros that had a severe housing bust followed by a big rebound. Now, prices nationwide are just 3% undervalued relative to fundamentals. That leaves fewer bargains and scant room for prices to rise without becoming overvalued. What’s more, with consumers expecting 2015 to be a better year to sell than 2014, more homes should come onto the market, cooling prices further. Nevertheless, despite slowing price gains, home-buying affordability will worsen in 2015 for two reasons. First, even these smaller price increases will almost surely outpace income growth. In 2013, incomes rose just 1.8% year-over-year in nominal terms, and a negligible 0.3% after adjusting for inflation. Second, the strengthening economy and the Fed’s response should push up mortgage rates.

2. The rental market will keep burning bright.

Next year will see strong rental demand and lots of new supply. The demand will come from young people leaving homes belonging to parents or roommates and renting their own places. Until now, they’ve been slow to leave the nest. But the 2014 job gains for 25-34 year-olds should lead to the rise in household formation we’ve been waiting years for. At the same time, the 2014 apartment construction boom will mean more supply in 2015 since multi-unit buildings take about a year to build. Will rent gains slow? Probably – provided that this new supply keeps up with formation of renter households. This surge of renters will probably cause the homeownership rate to fall. To be sure, the ranks of homeowners will probably rise. But an even larger number of young adults will enter the housing market as renters.

3. Single-family starts and new home sales could disappoint.

While apartment construction is breaking records, single-family housing starts and new home sales are still not much better than half of normal levels. They’ll improve in 2015, but not as much as we’d like. Our consumer survey suggests more people will try to sell existing homes. That would add to the supply on the market and possibly reduce demand for new homes. Also, the strongest source of housing demand will be young people getting jobs and forming households. But they’ll be moving into rentals and saving for a down payment rather than buying homes right away. Finally, the vacancy rate for single-family homes is still near its recession high, which discourages new construction. The apartment construction boom shows that where there’s demand, builders will build. But buyer demand for single-family homes simply hasn’t recovered enough to support near-normal levels of single-family starts or new home sales.

“If these predictions for 2015 sound similar to our predictions for 2014, you’re right. As the rebound effect fades and fundamentals take over, the recovery gets slower and the market starts to look more similar from one year to the next,” Kolko says. “But there’s good news here. Even though the recovery remains unfinished, the housing market is becoming more stable and more certain for buyers, sellers, and renters.”
