It's hard to tell without knowing which website you're talking about, and there can be many reasons.
- They could want too much for it. There's an expression in the note space that there are no bad notes, just bad prices.
- The collateral might not be complete.
- The seller may be unresponsive. (is it a company's website or an exchange like FCI?)
- Going back to them wanting too much for it, they may be using an AVM number that is way off and anyone doing basic due diligence knows it. (ie they claim the house is worth 200k and has equity, but it's obviously worth 150k and underwater)
- CT isn't in most people's top 5 for a few reasons. First you don't see that many notes from there as opposed to midwest and south east states, and second, north eastern states usually scare people because of taxes and liberal courts.
- They could have found a buyer and then he backed out, which happens.
You would have to be more detailed but these are a handful of basic reasons why some notes sit.
