– About the ILHM Luxury Market Report –

How do we do it?

We start at the zip code level. We look at all the zip codes in 31 metro areas around the country. For each metro area, we rank the zip codes by median price, take the market data from the top ten zips with median prices above $500k, and create a local composite that is representative of the top of the market.

Individually, we get a view of what’s happening in the luxury markets of each of these cities. We can slice and dice and look at data and trends in price, inventory, time-on-market, and more. When we aggregate them, we get a snapshot of the overall trends in the luxury market nationwide.

About the Data

The report relies on the proprietary Altos Research national data set. It is important to note that this is ACTIVE LISTING data, not historical MLS or closed transaction data. This is forward looking "what's happening now" data, not backward-looking "what happened a couple months ago" data. For more information: http://altosresearch.com/altos/website/Faqs.page

Tips on Reading the Report

Real Estate Price Trends

The price chart shows the current median single family home price in the area you are researching. Real estate market research begins with price trends. Watch this report each week to discern luxury market trends before you can read about them anywhere else.

Home Sales and Demand Trends

How long does it take to sell a home in your area? Pay close attention to the Days on Market. Not only does it tell you about the health of the market, but also how long you might expect it to take to sell a home. Or how quickly you should make an offer on the place you saw this weekend. Take advantage of this knowledge to optimize your home buying and selling experience. Note the trends! Housing

Market Conditions

Altos Research developed the Market Action Index™ for an at-a-glance measurement of market conditions. The Index is a barometer of real estate supply and demand. A value above 30 indicates demand is relatively robust, we call that a Seller's Market. Below 30 is a Buyer's Market. Also use the Market Action Index trends as a leading indicator for prices. When markets fall persistently into Buyer's territory prices will likely follow.

Homes for Sale

Inventory measures the number of properties for sale in a given real estate market and will fluctuate seasonally. Make sure you keep an eye on the Market Action Index (above) to gauge demand levels relative to inventory levels. If inventory increases as demand falls, you'll see the Market Action Index drop quickly.
