It varies based on so many factors.  

It varies by community - for September it ranged from 26 days to 4.9 months for the communities I service and do market reports for. DOM ranged from 6 to 53 days but it shifts each month. Real estate is local!

Days on the market up to 60 and now 6 months of inventory at the rate they are selling.  Nothing like 6 months ago.

In my hometown, we have a 0.5 months of inventory; average DOM 28; median is 5

1.4 Months of inventory for the largest county. 21 DOM.

Homes Sold in past 30 Day = 248

Homes Active at this time = 476

Obsorbtion Rate in for us  = 5.2 Months

I'm seeing 1.5 months of inventory and 43 DOM for average. 

Location and product are key factors for the set of numbers which I follow. Good response within days of listing, closings within 30-45 days and in demand properties still rule & speak for themselves regardless of inventory

Charlotte region's months of inventory remains in "seller territory" through September at just 1.6 month. Our average days on market are 22.

Depends on the property and how it is marketed.

Homes generally sell very quickly, land and commercial takes a little more work.

Depends on the town in, but average in Los Angeles County August was 16 days. So, yes, depending on the price range but we still have bidding wars.

I have a lot of markets I Work in, but nationwide I'm seeing ~2 months and 35-45 DOM as as a pretty common theme.  Inventory varies more drastically market to market than DOM has so far.

IN the Denver area for September it is 27 days in August it was 20 days

Average days on market is 49-60 days and inventory is at 4-5 months.  Quite a change from just two months ago.  And four months ago? If you listed a house it was under contract within the first 24-48 hours.  Not so today.

We are at a 1.1 month supply of homes here in Charlotte with an average of 18 days on the market but, regardless of that data, WE ARE IN A BUYERS MARKET!  

Buyers have the upper hand in negotiations as well as sellers are taking less for their homes - list-to-sales-price ratios are definitely falling. Talking to mastermind agents in our area, their challenge is setting seller expectations.
