Although home price gains rival those of the last decade’s bubble, home prices today look undervalued by 7%. Prices are overvalued only in a few California and Texas metros.
Home prices today are rising nearly as fast as they did during the peak bubble years of 2005-2006. Since that bubble helped push us into the Great Recession, we should all be on high alert for the next housing bubble. To track whether home prices are in or nearing bubble territory, today we introduce Trulia’s Bubble Watch, which is based on the most recent price data from the Trulia Price Monitor and other data sources.
So are we in bubble territory? No. Bubble-phobes can rest easy. Even with recent sharp home price increases, prices are still low relative to fundamentals and are far below bubble levels.
Back to Basics: How to Spot a Bubble
To see a bubble, you first need to know what you’re looking for. A bubble in home prices (or in the price of any asset – like stocks or even tulips) is when prices soar above their fundamental value. Fundamental value is based on supply, demand, and realistic expectations about the future. We all learned in Economics 101 that prices move back toward an equilibrium determined by fundamentals of supply and demand. In a bubble, however, rising prices encourage speculation and fuel further demand – up until when the bubble suddenly bursts and people rush to sell, which causes prices to accelerate downward, sometimes well below their fundamental value. Bubbles are notoriously difficult to predict and hard to confirm until after they’ve burst: it’s impossible to be sure whether price gains are justified by fundamentals until, if and when, a bubble bursts. San Francisco home prices, for instance, are the highest in the country; is that “irrational exuberance” by speculative homebuyers, or are those prices justified by strong job growth, high incomes, great weather, and constraints on the local housing supply?
To answer that question, we assess whether home prices are overvalued or undervalued relative to their fundamental value by comparing prices today with historical prices, incomes, and rents. Incomes determine how much people can pay for housing, and price increases aren’t sustainable if they push prices too high relative to incomes. Rents reflect how much people value housing even if they won’t benefit from price appreciation (as renters don’t, but owners do); the price-to-rent ratio is like the price-earnings (P/E) ratio for stocks. Using data from multiple sources (see footnote), we create several measures of fundamental value and combine them in order to calculate how overvalued or undervalued home prices are relative to fundamentals.
Home Prices are Undervalued 7% Nationally and Regionally in 91 of the 100 Largest Metros
We estimate that national home prices are 7% undervalued in the second quarter of 2013 (2013 Q2). During last decade’s bubble, prices were as high as 39% overvalued in 2006 Q1, then during the bust, fell to 15% undervalued in 2011 Q4. Therefore, even with the recent price increases, home prices nationally remain undervalued relative to fundamentals and much lower than in the last bubble. That’s why today’s price gains are actually still a rebound, not a bubble. This chart shows how far prices are from bubble territory:
Asking home prices rose nationally 8.3% year-over-year. Nine of the 10 markets with the biggest price gains also had job growth above the national average.
The Trulia Price Monitor and the Trulia Rent Monitor are the earliest leading indicators of how asking prices and rents are trending nationally and locally. They adjust for the changing mix of listed homes and therefore show what’s really happening to asking prices and rents. Because asking prices lead sales prices by approximately two or more months, the Monitors reveal trends before other price indexes do. With that, here’s the scoop on where prices and rents are headed.
Prices Up 8.3% Year-over-Year, Rising in 95 of 100 Largest Metros
In April, asking home prices rose 1.3% month-over-month, seasonally adjusted. Quarter-over-quarter, prices are up 4.3%, seasonally adjusted. Year-over-year, prices are up 8.3% nationally and are higher than one year ago in 95 of the 100 largest metros.

New homes dominate the market across the Sunbelt and typically cost more – and have more space -- than older homes. But in most markets, you can also find older homes with historical features and distinct architectural styles. In a few metros, like Charleston, SC, and Washington D.C., the oldest homes cost the most.
Would you rather have a newly-built home or a piece of local history? Across America today, you can find homes for sale that were built as long ago as the 19th century or as recently as yesterday. There’s no mistaking a 1920s Dutch colonial, a 1970s A-frame, or a 2000s home tricked out with the latest spa features. To guide you through the decades, we looked at listings on Trulia from the past two years and found descriptive phrases that are most characteristic of homes built in each decade. But just because you want a 19th century Victorian or a 1950s brick rambler doesn’t mean you can find one: each region of the country had its own construction heyday, and the age of homes for sale today in a local market reflect when in history that location had population growth and new home construction. So buckle up … it’s time to take a trip back in the time machine.
The Way Homes Used to Be: Homes Before 1940
San Francisco Victorians, New York pre-war buildings: old homes are part of local history in much of the country. But across the Sunbelt, population growth has been more recent, so truly old homes are rare. This interactive map shows the percent of on-market homes (as of the last week in March 2013) built in each decade in the largest major metros.
The oldest homes for sale – those built before 1900 – are concentrated in New England and upstate New York. More than 5% of homes currently listed in the Massachusetts metros of Peabody, Boston, Middlesex County, Springfield, and Worcester were built before 1900, along with the upstate New York metros of Syracuse, Albany, and Rochester. Allentown, PA, and Providence, RI, round out the 10 metros with the largest share of old homes for sale.

You’ll find a large share of homes built in the 1900s in San Francisco (6.4%) – especially just after the 1906 earthquake – while homes from the 1920s are easiest to find in New York (12.3% of on-market homes there were built in the 1920s), Los Angeles (9.7%), and several Ohio markets including Toledo, Akron, Dayton, and Cleveland. At the other extreme, there are essentially no homes from the 19th century across much of the South and the West. In fact, fewer than 1% of on-market homes were built before 1940 in Las Vegas, Fort Lauderdale, Phoenix, and other Sunbelt metros.
What’s special about old homes? Listings for homes built before 1900 are far more likely to mention exposed brick, pocket doors (which open by sliding into a “pocket” in the nearby wall rather than swinging open), carriage houses, and grand staircases than homes built in more recent decades. Homes from the 1900s mention tin ceilings, fir floors, and chimneys, while homes from the 1910s often call out kitchen and bathroom features like built-in buffets, claw-foot tubs, and china cabinets. In the 1920s, wood features were popular: properties from that decade call out gumwood trim and herringbone floors. Also in the 1920s, European styles were in vogue: listings mention original French doors, French windows, and Spanish styles. Homes from the 1930s are more likely to mention slate roof and glass door knobs, and curves were in fashion too, with coved ceilings and arched doorways. These popular listing words reveal the evolution of American architecture and building materials – you can see the five phrases that capture the character of each decade in our interactive map based on Trulia’s analysis of for-sale listings.
