How true are "Average days on the market" claims? .?

Question

I just read, that the average day on the market for single resident homes increased in the last 12 month from 108 to 128 days. Does that take in account, that the same house can be listed over and over "New" in the MLS?

Do you know about a true statistic?

I am really curious, because I know a lot of houses being on the market for more then 2 years, some 3.

Answer 1

Perhaps a National Statistic. In Miami / So Fla, Days on Market Could be 2 to 3 years or until foreclosure.

Answer 2

averages don't apply to specifics

if a home is listed on the MLS and taken off and put back on. . . unless there is a 3 month absence, it is counted as the same house, same listing

But if the house has been absent from MLS 3 months, it starts a new count. . . doesn't matter if homeowners change realtors, take it off and on, etc,
