The StreetEasy Manhattan Condo Market Index

Our index gives you a feel for how the Manhattan Condo Real Estate market performed over the past 15 years. For each month since January 1995, we were able to estimate a rate of return for the Manhattan market as a whole, and used January 2000 as the base period with a value of 1,000.

Read our Methodology Paper (PDF) for a detailed explanation of how we created this index. Essentially, we used a variation of the repeated sales regression analysis technique, with assorted filtering and our trademarked magical unicorn dust.
