2023 New Listing is showing a new trend

[Carlos Ptriawan]

The 2023 new listing trend is showing newer trend that's counterintuitive againts the previous 6 year trend, if you guys notice the pattern between 2017-2022 pattern is always having ~175-~200k difference between Q1 and Q2 followed by drastic faling between Q2 and Q4 ; but in 2023 the trend changes ! the slope is flattening, the spread between low and high is only about 100k now !! The black line represent 2023 below is almost "flat" which indicate the previous trend of seasonality is not as strong as before.

Where does it correlates to pricing ? I think if this becomes new trend, it just simply means much less supply continue to be available in market, more owner is keeping their house, shorter DOM and obviously it would create condition where volatility of price is reduced aka comps (either up or down) would be more flat or slightly higher. Of course, if this trend continue.  

This correlate to the price in Zillow home index which is also showing sort of "price stability" compare to 2022 level.
Any Statistician here ? what do you think ?
