The astonishing worth of home listings Americans are sitting on as market grinds to a halt

There are so many homes listed for sale in the US that the combined worth is a jaw-dropping number that has hit an all-time high.

A total of $698 billion worth of homes are currently for sale across the country, Redfin reports.

That number is up 20.3 percent from a year ago.

It's the highest dollar amount ever sitting on the market at once, with many sellers offering concessions like slashing prices in order to move their home. 

The report is based on an analysis of listings going back through 2012.
