NAR analysis says sales of existing-homes will hit highest levels since 2006, Wall Street Journal reporter Laura Kusisto writes.
Additionally, the NAHB's Robert Dietz expects that 2015 will be the first time during the recovery that the growth of single-family home starts will exceed apartment starts.
The volume of sales can be hurt if interest rates and prices rise, which slows the need for more new-home construction.
Driving sales are strong job growth, low interest rates, and a gradual loosening of lending standards. Chief Economist of the NAR Lawrence Yun said the association expects home sales to end up around 5.3 million in 2015, compared to 4.9 million sales in 2014.
