There’s a home in Telluride that would make Flo from Progressive proud. Potential buyers can name their price on this 5,400-square-foot house at 220 Cortina Drive, which hit the market Aug. 12. But don’t expect to toss a “Price is Right” bid — the window for offers is $3.75 to $4.195 million. “220 Cortina Drive was originally listed for $4.995 million and wasn’t receiving any offers, so we decided to take a different approach,” said Mike Russo, founder and developer of SparkOffer, a transaction platform that aims at a more transparent way to connect sellers with buyers.
