Inventory Update: Why The Jump?
A: Because the good folks at Streeteasy.com are doing their job to solve the problem of transparency for Manhattan real estate! Here is the update.
You may have noticed that inventory for Manhattan jumped today by just under 700 new listings, bringing total active inventory (co-ops, condos, townhouses in Manhattan excluding duplicates, FSBO's and open listings) to about 7,659. The reason for the jump is that Streeteasy has expanded their listings database to include "a bunch of new sources in Manhattan". According to one of the tech guys over at Streeteasy, "...this should be the last big change, at this point we have pretty good coverage".
In a housing market without a standardized MLS system, new sites such as Streeteasy have emerged to solve the lack of transparency that is so troubling for many buyers and sellers. Transparency is a good thing, and knowing that the focus is on quality and accurate coverage makes me very proud to have partnered with such a great startup!
Here is the current inventory trend for Manhattan for the last two weeks:

I have spent the past 3-4 weeks working with developers on the new charting system for you guys, and let me say, it is looking sweeeeeeet! Very soon, the landscape will change and you will have a real-time analytical tool to monitor Manhattan total listings inventory, price reductions, new listings, and contracts signed.
The data will never be perfect without a regulated standardized MLS system, but I am extremely pleased with the accuracy of our efforts thus far. Data may not be 100% real-time, but it is accurate and in-line with respected published quarterly reports by Jonathan Miller.
For all those that can't wait, here is another glimpse into what is to come and one reason why I have been discussing the rising trend of inventory since the low in mid-December:

I hope it's worth it guys!!

A question... in other blog posts, you've written, if I remember correctly, that when Manhattan inventory reaches the 7750-8250 range, fierce seller competition might ensue. Does Streeteasy's new method of counting mean that the range for fierce seller competition should be revised upwards (say, 8350-8850)?
I ask because it's not as though 600 new listings have come on the market; it's more like Streeteasy has only just begun to count listings that were presumably there all along.

Louis - true, these listings did not just pile on yesterday, rather, streeteasy is getting more accurate in its coverage.
Maybe there is 8,250 listings right now we dont know about. Maybe 7,300 because contracts signed have not been caught up yet. Its not perfect.
However, use much caution with my statements about fierce seller competition at the 8,250+ level. I am using the top inventory point hit in past 5 years as the level that would tell me there should be some form of competition amongst sellers due to sluggish demand.
What the exact # is, we'll never know. To be safe, lets up it to 9,000+ or so. In that scenario, it would be clear that buyer demand has slowed considerably. We still dont know how this will unwind, so lets just interpret as we go and Ill tell you what I see in field.

How has the rising inventory in Manhattan affected rental rates? Are rental rates on the rise because less people are inclined to buy? Have you seen the 65,000 Wall Street lay offs have an impact on rental rates? With a hiring freeze on Wall Street and more lay offs to come, will rental rates decline?

I've been glued to the total inventory numbers ever since you revamped the website. Personally, I am waiting to see the numbers go to 10,000 (if that ever happens this summer.) I am sure it will have a psychological effect with the sellers & buyers. The press would just eat it up. If not, then I guess real estate as usual.

Great job Noah ... you really have something unique with the inventory tool.
It's very impressive.
You should be very proud of your accomplishments.

Good work keeping track of the inventory! Maybe in the future, you can break down the inventory based on # of bedrooms and price ranges? Just a suggestion.

I've already had hats made that say "Inventory 10,000!!!"

Can the expanded database provide for retroactive postings of more accurate inventory trend lines?
Taking away the small number of extreme high-end sales at a few trophy properties and assuming (correct?) the number of closed sales didn't change, the depiction of Manhattan as an island of calm in the midst of a national crisis may have been unintentionally misleading.
