How did the 2015 housing market take shape in Boston?

The Greater Boston Association of Realtors (GBAR) released its final stats on the 2015 housing market, and unsurprisingly, the association’s numbers hold many insights on where the market is heading.

Here were the four big takeaways from the report:

1. A Single-Family Market – Although home sales in Greater Boston were positive in 2015, rising 4.55 percent from 2014 to 2015, those gains were unequally distributed. So while the single-family market posted 14,313 sales – a strong 7.7 percent increase – condo sales were up a barely positive 0.6 percent.

2. Prices Never Fall… – Unsurprisingly, median sales price closed out the year with strong increases, but unlike in sales, condos led the way. While the single-family median price rose 3.7 percent to $475,000, the condo price rose 8.4 to $450,000. In the last two years, single-family prices have risen 9.2 percent, and condo price have jumped 14.94 percent.

3. …and Inventory Never Rises – Running hand in hand with the market’s rising prices has been inventory, which only continues to fall. At the close of the year, there were 2,362 single-family homes on the market, down 17 percent from a year ago to a 1.8-month supply; condo inventory is in even worse shape, down 7.7 percent to just 1,206 (or a 1.4-month supply). According to GBAR, single-family inventory has fallen in 50 of the last 51 months, while condo inventory has fallen an astounding 53 consecutive months.

4. Pointing to a Bright Future – One undeniable bright spot in GBAR’s report came in pending sales, which rose for the ninth consecutive month in the single-family market and are up 20 percent over where they were a year ago; Dec. 2015 was the most active month of contract signings since 2003.
