When you’re selling something, it helps if what you’re selling is in demand, but is also in low supply. Why? That makes it even more desirable since there’s not enough to go around. That’s exactly what’s happening in the housing market today. There are more buyers looking to buy than there are homes for sale.

To tell the story of just how low inventory is, here’s the latest information on active listings, or homes available for sale. The graph below uses data from Realtor.com to show how many active listings there were in September of this year compared to what’s more typical in the market.

As you can see in the graph, if you look at the last normal years for the market (shown in the blue bars) versus the latest numbers for this year (shown in the red bar), it’s clear inventory is still far lower than the norm.
