The Greater Boston Association of Realtors released the latest housing data for the Boston area earlier today, and as usual, the association provided a detailed (if gobsmacking) view of the region’s housing market.

Below, we have spotlighted the four most notable aspects of the report:

1. Home Sale Slide – In October, home sales in both the single-family and condo markets declined, falling 15 and 1.3 percent, respectively. Although the two market segments remain ahead of where they were last year – year to date, single-family sales are still up 1.5 percent, while condo sales are up 4.8 percent – another two months of declines could threaten those YTD gains, especially if the single-family market keeps falling by double digits.

And given that pending sales were down 4.7 percent for single family and flat for condos, that may very well be the case.

2. Inventory Apocalypse – One undeniable cause of the market’s weak sales is low inventory, and in October, supply continued to fall like the autumn leaves. On the single-family side, inventory fell 27.3 percent, and is now at a 2.4-month supply. For condos, the situation is even worse – inventory dropped 25 percent to a 1.8-month supply.

Moreover, October offered little relief in the form of new listings. For single family, new listings were down 16.4 percent, and for condos, they were down 7.8 percent.

3. A Seller’s Market – There are fringe benefits to a low-inventory market, and Greater Boston’s home sellers are enjoying those perks with very strong price growth. At $526,300, the median sales price for single-family homes was up 10.8 percent year-over-year, while for condos, sales price is up 5.3 percent to $479,238. Year-to-date prices are even higher – $541,000 for single family (up 4.4 percent) and $487,455 for condos (up 8.3 percent).

4. Times a Wastin’ – Finally, the low inventory market has also greatly increased the demand for the listings that remain on the market, and no measurement is more indicative of that demand than the ‘days on market’ stat. According to GBAR, it took an average of 56 days for single-family homes to sell, a 12.5 percent decline from a year ago; for condo listings, it only took 40 days, which is down 20 percent from last year.
